ABSTRACT The present study related to boxing athletes' mental toughness and physical fitness performances with Big Five Factors. For this, the sample was composed of eleven recreational boxers who competed at the state level and were regularly training (technical and tactical) 4 times a week during the evaluation period. The 44-item Big Five Inventory (BFI) measures the Big Five dimensions of Conscientiousness, Agreeableness, Neuroticism, Openness, and Extraversion and the 14-item Sports Mental Toughness Questionnaire (SMTQ) were applied with Strength, Power, and Endurance Tests, Pearson and Spearman's correlations were used to verify the association between BFI, physical and mental tests, respectively, p≤.05. Our results demonstrated that significant and strong correlation between agreeableness factor and sit-ups test, with 40.85±12.36 freq./min (r=.72, p=.02) and, in SMTQ, a strong correlation between Neuroticism and Control [10(9;12) score, r=.76, p≤0.01], Constancy [10(9;12) score, r=.84, p≤0.01] and Total SMQT [37(34;37) score, r=.84, p≤0.01]. In conclusion, these results suggest that Neuroticism factors are associated with mental toughness, while the agreeableness factor is related to muscular endurance capability. Mental toughness and endurance results are associated with boxers' personalities whose drive motivates them relentlessly towards success and promotes thriving in boxing training environments or during championships.Effects of resistance training on consecutive and non-consecutive days on hormonal, neuromuscular and morphological responses in recreationally trained men10.1590/1980-0037.2023v25e858482023-01-13T19:36:02.794000Z2020-08-09T06:49:00.307000ZLopes, Charles RicardoBrigatto, Felipe AlvesCamargo, Júlio Benvenutti Bueno deGermano, Moisés DiegoMarchetti, Paulo HenriqueAoki, Marcelo SaldanhaPolitano, Hugo

abstract The purpose of the present study was to investigate the effect of two recovery periods between consecutive and non-consecutive days in strength training sessions on hormonal, neuromuscular and morphological variables in recreationally trained men. Nineteen young men completed the study and were randomly divided into two groups: 24R, 24-hour recovery group (n = nine) and 72R, 72-hour recovery group (n = ten). The strength training program (RT) lasted six weeks with two serial routines, with a weekly frequency of four times. The saliva sample was collected once a week in the morning to determine salivary testosterone. The 1RM, jump against movement and body composition tests were performed in the pre- and post-training periods. As for salivary testosterone, there was no significant effect with respect to time and between groups. Both groups improved maximal strength in terms of intervention time in the barbell bench press and in the leg press 45º, not differing between groups and body composition showed significant interaction in time to body fat percentage ∆% = -14.6 ± 10.0 (24R) and -17.2 ± 10.9 (72R); p = 0.00, fat mass ∆% = -13, 7 ± 9.2 (24R) and -18.2 ± 13.0 (72R); p = 0.00 and fat-free mass ∆% = 3.5 ± 2.7 (24R) and 2.5 ± 2 .8 (72R), p = 0.00. The recovery periods 24 and 72 hours between sessions induced similar responses in the parameters investigated in recreationally strength-trained men.Estimation of fat mass in Southern Brazilian female adolescents: development and validation of mathematical models10.1590/1980-0037.2023v25e787112023-01-13T19:36:02.794000Z2020-08-09T06:49:00.307000ZCintra-Andrade, Joaquim HuainaRipka, Wagner LuisLeite, NeivaUlbricht, Leandra

abstract This study aimed to develop and validate the first mathematical models, based on anthropometric properties, to estimate fat mass (FM) in a heterogeneous sample of female adolescents. A cross-sectional and quantitative study conducted with 196 individuals aged 12 to 17 years from the metropolitan region of Curitiba, Paraná, Brazil. The participants were randomly divided into two groups: regression sample (n = 169) and validation sample (n = 27). Dual-energy X-ray absorptiometry (DXA) was used as the reference method to determine body fat in relative and absolute values. Stature, body mass, waist girth and triceps, subscapular, biceps, iliac crest, abdominal, front thigh and medial calf skinfold thickness were defined as independent variables and measured according to an international technical protocol. Statistical analyzes used the Ordinary Least Square (OLS) regression model, paired t test and Pearson correlation. Four multivariate mathematical models with high determination coefficients (R2 ≥90%) and low estimated standard errors (SEE = ≤2.02 kg) were developed. Model 4 stands out for its low number of independent variables and significant statistical performance (R2 = 90%; SEE = 1.92 kg). It is concluded that the four mathematical models developed are valid for estimating FM in female adolescents in southern Brazil.Relationships of field-normalized and non-normalized scientometrics with the Physical Education Web-Qualis grades10.1590/1980-0037.2023v25e897432023-01-13T19:36:02.794000Z2020-08-09T06:49:00.307000ZKons, Rafael LimaLopes, Marcus Vinicius VeberMilan, Fabrício JoãoMilistetd, MichelSilva, Kelly Samara daDetanico, DanieleNascimento, Juarez Vieira

abstract This study aimed (1) to verify the relationship between the JIF, Eigenfactor, Citescore and SJR metrics of Physical Education journals throughout Qualis 2013-2016; and (2) to analyze their associations with the field-concerned Web-Qualis grades (based on the 2013-2016 quadrennium criteria). WebQualis grades, which refers to 2015-2018 data, were acquired by accessing officially available data. The scientometrics Journal Impact Factor (JIF), Citescore, Eigenfactor, and Scimago Journal Rank (SJR) for the years 2013 to 2016 and 2018 were extracted from official Clarivate Analytics and Elsevier sources. Approximately half of Physical Education journals included in the 2018 WebQualis database were indexed in Web of Science Collection and Scopus databases. The main results demonstrated high and stable appeared bivariate correlations between all scientometrics from 2013 to 2016. Both JIF, Eigenfactor, Citescore and SJR were associated with WebQualis grades. However, better adjustment of parameters was observed in the model that included SJR as the WebQualis predictor. The field normalized SJR appeared to better predict the WebQualis defined by the 2013-2016 Qualis criteria, which includes the adherence indicator. If researchers consider that distinct research areas are not equally weighted and require specific evaluation, as the authors suggest, use the normalized metrics to classify journals in Brazilian scenarium.Relative age in Brazilian swimmers and para swimmers10.1590/1980-0037.2023v25e909902023-01-13T19:36:02.794000Z2020-08-09T06:49:00.307000ZJesus, Karla deSilva, Geovani Messias daSantos, Vitória Miranda dosJesus, Kelly deMedeiros, Alexandre Igor Araripe

abstract This study aimed to analyze the relationships between swimming competitive events, functional classification and relative age and to detect if the relative age affects performance in Brazilian swimmers and para swimmers. Data were retrieved from public databases and birth dates were classified in four quartiles (Q1 = January-March; Q2 = April-June; Q3 = July-September; Q4 = October-December). Descriptive statistics, Chi-square tests and ANOVA were used. The 50 m freestyle is the competitive event with 2349 swimmers, followed by 100 m (n = 1817) and 200 m freestyle (n = 905), and 200 m butterfly with 42 swimmers. Para swimmers are mainly distributed to S14, S6 and S5 functional classes (n = 140, 87 and 45), and individual medley events were less represented at SM3, SM9 and SM11 (n = 1 swimmer). Most of swimming events (86.36%) and para swimming functional classes (51.43%) are represented by swimmers and para swimmers born in the first and second quartiles. Moderate associations between functional classification and relative age were observed (p < 0.0001, Cramer’s V = 0.277). No effects of relative age on swimmers and para swimmers’ performance were noticed (p > 0.05). The great functional class seems to be related to great para swimmers’ relative age. Quartiles distribution shows the advantage of being born in the first months of the year to be registered among the most talented Brazilian swimmers and para swimmers.The influence of gender and age on foot structure and plantar pressure in asymptomatic adults10.1590/1980-0037.2023v25e866932023-01-13T19:36:02.794000Z2020-08-09T06:49:00.307000ZRogerio, Fernando Raphael Pinto GuedesGuedes, Dartagnan Pinto

Abstract The aim of the study was identify the influence of gender and age of healthy adults on the foot structure and the plantar pressure during gait. Sample comprising 608 women and men participants. To identify the structure of the foot, anthropometric measurements of both the total and the truncated length of the foot, the width of the forefoot, and the heights of the back and navicular were taken. Peak pressure and plantar contact area in three foot-masks (forefoot, middle foot, and hindfoot) were considered markers of plantar pressure. The data were analyzed by two-way variance analysis. No significant influence of age on the foot structure dimensions was identified; however, women presented measures equivalent to the five significantly smaller anthropometric markers. As for the peak plantar pressure, both males and females showed statistically similar values, but significant differences were observed for age. As to the plantar contact area, while age did not have significant influence, men showed significantly higher values in the three foot-masks. The findings suggest that gender influences the foot structure and the plantar contact area, while age influences the peak of plantar pressure.Comparison of the indicative of muscle dysmorphia among recreational and competitive Crossfit athletes10.1590/1980-0037.2023v25e849482023-01-13T19:36:02.794000Z2020-08-09T06:49:00.307000ZOliveira, Daniel Vicentini deFreire, Gabriel Lucas MoraisSouza, Mariana Ferreira deXavier, Sherdson Emanoel da SilvaMoraes, José Fernando Vila Nova deNascimento Júnior, José Roberto Andrade do

Abstract This cross-sectional study compared the indicative of Muscle dysmorphia in CrossFit athletes. Participants were 276 male and female CrossFit athletes with an average age of 28.56 ± 8.08 years. A questionnaire was used with questions about age, practice time and frequency of Crossfit practice, as well as the questionnaire of the Adonis complex. Data analysis was conducted through Kolmogorov-Smirnov and Mann-Whitney tests, and Spearman correlation (p<0.05). The adopted significance was p<0.05. The results showed that men obtained higher indicative of muscle dysmorphia in comparison to women as well as competitive athletes showed higher score than recreational athletes (p<0.05). It was found significant (p<0.05) and negative correlation of the indicative of muscle dysmorphia with training frequency (Rho=-0.51) among recreational athletes, and positive correlation (Rho=0.19) among competitors. It is concluded that being male and having a competitive profile are actors in the presence of Muscle dysmorphia in CrossFit athletes.Relationship of speed and unilateral vertical jump performance of basketball athletes10.1590/1980-0037.2023v25e897322023-01-13T19:36:02.794000Z2020-08-09T06:49:00.307000ZNascimento, Ygor Gabriel Almeida doFaria, Cristiano Souza deLima, Leonardo Emmanuel de MedeirosRica, Roberta LukseviciusBocalini, Danilo SalesFigueira Junior, AyltonLauria, Vinicius TononGuedes Júnior, Dilmar PintoSilva, Rodrigo Pereira da

Abstract Basketball is a sport practiced around the world in this way, performances tests especially with low-cost and accessible are suggested to adjust the training. The 00aim of present study was to evaluate and correlate the speed and jump performance of lower limbs of basketball athletes from the Praia Grande, city of São Paulo, Brazil. Twelve male athletes (6.92 ± 2.57 years of pratice) from the Basketball team of Praia Grande City, aged 18.7 ± 0.6 years, height 1.85 ± 0.06, body mass 83.66 ± 10.16 kg were evaluated. The athletes were submitted to test sessions using the protocol for evaluating the maximum speed of 20 meters and the unilateral vertical jump. The speed on 20 meter test was 3.53 ± 0.20 seconds. Although an asymmetry of 17.81 ± 14.64% was found, no statistical difference (p = 0.817) was found between the dominant (36.50 ± 7.36 cm) and non-dominant (35.92 ± 5.63 cm) of vertical jump performance. Additionally, correlation between 20-meter test and values jump was found to dominant leg (p = 0.042) but not to non-dominant leg (p = 0.704). In conclusion, although asymmetry was found between members of the dominant and non-dominant side of the pitch, did not show any difference in the vertical jump.Validity evidences of two Sports-Pedagogy-related scales: socio-educational and autonomy development in youth sports10.1590/1980-0037.2023v25e902322023-01-13T19:36:02.794000Z2020-08-09T06:49:00.307000ZGonçalves, Gabriel Henrique TreterBalbinotti, Marcos Alencar AbaideGinciene, GuyBrasil, Vinicius ZeilmannKlering, Roberto TierlingBalbinotti, Carlos Adelar Abaide

Abstract Competition is the essence of sports and, when conceived having participants as references, it can contributes to the development of different pedagogical contents, among them, socio-educative aspects and autonomy. The purpose of this research was to demonstrate the first validity evidences of two scales for supporting socio-educational and autonomy development in youth sports; both are part of the Battery of Tests Gonçalves-Balbinotti of Pedagogical Contents’ Development Support in Youth Sports. We aim to estimate their internal structures, test their stabilities and estimate their internal consistency. A sample of 210 coaches answered the scales related to socio-educational and autonomy development, which presented second order two-factor structures with significant factor loadings (> 0.40) and explaining 80.6% and 73.2% of the constructs’ total variance, respectively. The results related to the model fit were satisfactory (X2/df < 2.00; AGFI > 0.95; RMSEA < 0.05; CFI > 0.95; TLI > 0.95). The results regarding the internal consistency (0.786 < α < 0.913 for the factors; αSE = 0.889; αAu = 0.870) assure the precision of the measures and the reliability of their uses according to their purposes. The results answer the main and specific purposes of this research and indicate the safe use of these two scales.Pinch size can affect the skinfold thickness measurement and interfere in the estimation and classification of body adiposity10.1590/1980-0037.2023v25e902822023-01-13T19:36:02.794000Z2020-08-09T06:49:00.307000ZCintra-Andrade, Joaquim HuainaBrito, Filipe Oliveira deFreire-Correia, Maria IzabelCosta, Roberto Fernandes daRipka, Wagner Luis

Abstract The aim of this study was to verify the effect of pinch size on skinfold thickness measurement and the consequent interference in the estimation and classification of body adiposity components. Cross-sectional and quantitative study carried out with a sample of 29 subjects recruited from a university in the city of Fortaleza, Ceará, Brazil. Four measurement steps were performed at each site of the eight chosen skinfolds. The first step was performed with a subjective-landmark and the three subsequent steps with fixed-landmarks defined with an expanding secondary line at 2 cm intervals. Body adiposity components were determined from the skinfold thickness measured at each landmark. Repeated measures ANOVA and Bland-Altman agreement analysis were applied. The subjective-landmark was chosen as the dependent variable. The 6 cm-landmark showed similarity and statistical agreement with the subjective-landmark for all skinfolds except the thigh, and with the sums of five and eight skinfolds. All fixed-landmarks showed agreement below the cut-off point for the percentile classification of subcutaneous adiposity and normative relative body fat. Variation in pinch size is an important source of TEM that can affect the reproducibility of skinfold thickness measurements and interfere in the estimation and classification of the molecular and tissue component of body adiposity.Body composition indicators in the metabolic syndrome risk prediction in 6-10-year-old children10.1590/1980-0037.2023v25e852892023-01-13T19:36:02.794000Z2020-08-09T06:49:00.307000ZQuadros, Teresa Maria Bianchini deGordia, Alex PinheiroMendes, Edmar LacerdaAndaki, Alynne Christian Ribeiro

ABSTRACT The aim of this study was to develop percentiles of body composition indicators and determine cutoff points to predict metabolic syndrome (MS) risk in 6-10-year-old children. This is a cross-sectional, population-based epidemiological study with the participation of 1480 schoolchildren aged 6-10-year. Anthropometric assessment (body mass, height, and skinfolds) and blood pressure measurement were performed in schools. The body mass index (BMI), as well as the body fat percentage (%BF), lean body mass (LBM), fat body mass (FBM), were calculated according to standardized formulas for children. Blood collection to assess the lipid and glycemic profile was also performed at school, on pre-established days and times. The MS diagnosis was determined based on changes in triglycerides, HDL-c, blood glucose, waist circumference, and blood pressure. The LMS method was used to develop the percentiles, the area under the ROC curve (AUC) to identify the accuracy of the indicators, and the sensitivity and specificity to determine the cutoff points. FBM and %BF had significantly higher values in girls, who also had lower values for %LM compared to boys (p<0.05). The indicators of body composition, BMI, FBM, and %BF were accurate in predicting the MS risk for both sex at all ages. The main indicators of body composition to predict the MS risk, in both sex, were BMI, FBM, and %BF. These findings suggest that simple anthropometric measurements, which can be performed in clinical practice, have the potential to direct non-pharmacological actions.Linear and undulating resistance training programming induce similar outcomes on physical fitness in elderly women10.1590/1980-0037.2023v25e775282023-01-13T19:36:02.794000Z2020-08-09T06:49:00.307000ZSilva, Surama do Carmo Souza daPires, Flavio de OliveiraBatista Junior, Marifran ToméSerra, Larissa de Lourdes PadilhaReis, Carlos Brendo FerreiraAbreu, Leudyenne Pacheco dePereira, Paula Tâmara Vieira TeixeiraCabido, Christian Emmanuel TorresLeite, Richard Diego

Abstract The aim of the present study was to analyze the effect of two different types of resistance training programming (linear and daily undulating) on submaximal strength and functional capacity in elderly women. Twenty-two participants (64 ± 3 years) were randomly assigned to 2 training groups: linear programming (LP; n=12) and daily undulating programming (DUP; n =10). Functional capacity and submaximal strength (10RM) were analyzed before and after 12 weeks of resistance training. The results demonstrated improvement on strength and functional capacity after the resistance training period (p ≤ 0.05), except for the Bench Press (p = 0.30), for both groups DUP and LP. The Effect Size was, respectively, high for DUP (timed up and go test = -2.07, and timed sit test= 4.69), and high for LP (horizontal leg press = 2.35). For all other results, the effect size was trivial or small. No statistical difference was observed between programming models. The LP and DUP trainnings have similar results in increasing submaximal muscle strength in elderly women inexperienced in RT after 12 weeks of intervention (p ≤ 0,05). However, DUP appears to be more effective in increasing functional capacity. In practice, the professional can use both the LP and the DUP to improve the level of fitness in the early stages of training in this population. However, when the goal of programming is to increase functional capacity, DUP can be prioritized.Acute exercise modulates the mental stress-induced responses in healthy and obese young adults10.1590/1980-0037.2023v25e895262023-01-13T19:36:02.794000Z2020-08-09T06:49:00.307000ZCavalcante, AndréAraújo, Jaqueline AlvesNonato, Laura CristinaFerreira, Jacielle CarolinaCambri, Lucieli Teresa

Abstract The aim of this study was to verify whether obesity and acute physical exercise could influence the reactivity to mental stress. Twelve normal weight (NW) and ten obese (Ob) (31.82% women), normotensive individuals between 18 and 40 years old were evaluated. The Stroop color test was performed under two conditions: 1) Baseline and 2) 30 min after the end of aerobic physical exercise. Individuals performed 30 min of physical exercise (NW: 3.38 and Ob: 2.99 km·h-1; p< 0.05) between 50-60% of heart rate reserve (NW: 139±7 and Ob: 143±7 bpm). The reactivity to mental stress for systolic blood pressure - SBP (Δ2 min) and diastolic blood pressure - DBP (Δ2 and Δ4 min) was lower (p< 0.05) in Ob compared to NW group. The SBP reactivity to mental stress was less (p< 0.05) post-exercise in all moments (Δ2 and Δ4 min), regardless of obesity, while the DBP reactivity to mental stress was less post-exercise, only in NW. BP reactivity to stress correlated negatively with obesity indicators (r/Rho = - 0.42 to - 0.64), under the baseline condition, but not post-physical exercise. Obesity blunted BP reactivity to mental stress in normotensive young adults. Moderately-intensity acute aerobic exercise reduced SBP reactivity to mental stress, regardless of obesity, while it reduced DBP reactivity to mental stress, only in NW. In summary, acute physical exercise may be a one means to prevent cardiovascular changes.Association between the risk of chronification of musculoskeletal symptoms and sleep quality in Military Firefighters of the Federal District10.1590/1980-0037.2023v25e859132023-01-13T19:36:02.794000Z2020-08-09T06:49:00.307000ZOliveira, Daltro Izaias Pelozato deMota, Maria Augusta de AraújoConceição, Vanessa Barros daAgner, Guido FregapaniAndrade, Anderson Lúcio Souza deClael, SachaMartins, Wagner Rodrigues

Abstract Musculoskeletal symptoms (MS) can derive from injuries or dysfunctions that affect biological tissues such as muscles, bones, and nerves, among others. Military Firefighters (MF) exercise their activities exposed to varied and complex biological conditions, in which the physical demands are intense. Shift work is another remarkable characteristic of the career, which is associated with sleep disorders. Our objective was to estimate the association between the risk of chronification of MS and sleep quality in MF with MS. Our study is a Cross-Sectional Observational Study, whose sample was composed of 753 BM from the Federal District. The analysis was performed with a Sample Characterization Questionnaire, Örebro Musculoskeletal Symptoms Screening Questionnaire (OMPSQ) and the Pittsburgh Sleep Quality Index (PSQI), answered remotely. Statistical analysis used the Spearman Correlation test, p<0.05. The correlation between OMPSQ and PSQI was rated moderate, demonstrating that sleep quality has an influence on the chronification process. The average of the evaluation of Sleep Quality through the PSQI is 8.79, indicating that military personnel present a deficient quality of sleep. There was a correlation between the PSQI score and the OMPSQ of 0.542 (p<0.001), a moderate correlation between the variables. We conclude that MF show correlation between SM and sleep quality, indicating a moderate relationship between the variables, where sleep quality explains 25% of SM. We found that most MF were classified as Low Risk for chronification of SM.Physical and motor profile of children between 6 and 10 years old according to levels of cardiorespiratory fitness10.1590/1980-0037.2023v25e943962023-01-13T19:36:02.794000Z2020-08-09T06:49:00.307000ZNascimento, Érico Martins doChaves, Raquel Nichele deRodriguez-Añez, Ciro RomelioRibas, Michele Caroline de Souza

Abstract This study aimed to compare the physical profile and motor profile of children from 6 to 10 years old, according to their level of cardiorespiratory fitness (CRF). Participated 2036 children from 6 to 10 years old from São José dos Pinhais - PR. Assessed variables were stature, corporal mass, Body mass index (BMI), physical fitness (PF), and gross motor coordination (GMC). The CRF was assessed by the total distance during the 6 minutes walking test. A battery of tests KTK evaluated the GCM. The children were classified according to their levels of CRF (low-moderate-elevated). Differences between groups were tested using ANOVA one way. Data analysis was made in the SPSS software, with a meaningfulness of 5%. Children with low levels of CRF showed higher values of adiposity. On the PF tests, children with low levels of CRF showed higher values of prehension and worse performance in the other tests. Regarding GMC, children with low levels of CRF had lower coordinative performance. Meaningful differences were found in the comparisons between different groups (low-moderate, low-elevated) with an advantage in the results in moderate levels of CRF. Obtaining average levels of CRF can bring protective benefits in other variables in children's growth process and development during infancy. Evaluating the CRF doesn't only get a momentary evaluation. Still, it can also do the monitoring of an essential variable of health, as well as indicate a predisposition about other physical-motor variables.Talent identification and development in Olympic triathlon: a perspective from Brazilian coaches10.1590/1980-0037.2023v25e905622023-01-13T19:36:02.794000Z2020-08-09T06:49:00.307000ZVieira, Leandro AlbuquerqueWerneck, Francisco ZacaronCoelho, Emerson FilipinoMiranda, LucianoLima, Jorge Roberto Perrout de

Abstract The knowledge of coaches has been used in research on talent identification and development. The objective was to investigate how Brazilian triathlon coaches identify talents and what is the importance of different factors and indicators for the development of young triathletes. 37 coaches (89% male; 36.2 ± 8.3 years; 43% international competitive level) answered an online questionnaire about anthropometric, physical-motor, technical, tactical, psychological and environmental characteristics. On a scale of 1 (not very important) to 5 (extremely important), coaches indicated to what extent a factor/indicator of sporting potential was important for talent development in triathlon. 45.9% of the coaches perform talent identification, mainly by physical-motor tests and triathlon simulations. In talent development, the physical-motor factor was the most important, followed by the technical, psychological and anthropometric factor, and finally the tactical and environmental factor. Most coaches considered as extremely important the following indicators: determination (70%), aerobic endurance (65%), specific swimming skills (62%), ability to withstand pressure (59%), and efficiency of the cyclic gesture of swimming, cycling, and running (57%). We conclude that Brazilian triathlon coaches identify talents mainly through batteries of tests and triathlon simulations and consider the physical-motor factor the most important for the development of young talented triathletes, but not the only one.Influence of walking and running on patellofemoral pain10.1590/1980-0037.2023v25e784082023-01-13T19:36:02.794000Z2020-08-09T06:49:00.307000ZSilva, Samuel Cézar AlexandreCarvalho, Brenda Egito deSantos, Walmir Romário dosSantos, Wlaldemir Roberto dos

Abstract Due to the ease of its practice, walking / running can be performed in such a way that there is no adequate control or monitoring, resulting in the appearance of injuries, highlighting patellofemoral pain. Thus, the present study aimed to verify the levels of patellofemoral pain in walk / run practitioners. The sample consisted of 318 individuals, selected in a non-probabilistic manner, for convenience and adherence, including over 18 years old, both sexes, living in the state of Pernambuco, Brazil, who practiced walking / running. Data collection was performed using an online questionnaire on the google platform. Participants who agreed to participate answered a sociodemographic questionnaire, the International Physical Activity Questionnaire (IPAQ) and a subscale of patellofemoral pain and osteoarthritis of the KOOS questionnaire. Data were presented using descriptive statistics (mean and standard deviation), submitted to inferential statistics using Student's t test, ANOVA with Bonferroni's post hoc to show the effect of comparisons, considering a significance level of 5% (p <0.05). There were no significant differences between the variables analyzed (p = 0.599; ES = 0.06), suggesting that there is no difference in patellofemoral pain in practitioners of walking / running between the sexes and different levels of physical activity; research with larger samples and monitoring of more variables, in the search for more assertive results, should be carried out.Factors associated with the practice of physical activity among university students in social isolation during the covid-19 pandemic10.1590/1980-0037.2023v25e901912023-01-13T19:36:02.794000Z2020-08-09T06:49:00.307000ZRocha, Brenda Morgana SouzaSouto, Matheus Frota OliveiraMendes, Victor Carvalho NarcisoFerreira, João Vitor BragaAzevedo, Eduardo de OliveiraCunha, Ana Luiza Lafetá Prates EvangelistaRocha, Josiane Santos BrantPinho, Lucineia de

Abstract This study sought to analyze the practice of physical activity (PA) among university students, during the COVID-19 pandemic, and associated factors. This is a cross-sectional study with an analytical approach, carried out with 857 university students enrolled in higher education institutions in Montes Claros, in the state of Minas Gerais. Data collection was carried out using the Google forms, which was shared via social networks, containing questions regarding sociodemographic profile, physical activity, clinical factors, and behavioral and health habits. A descriptive exploratory analysis of the data was carried out, with frequency distribution of the study variables. Subsequently, bivariate analyses were performed and the associated variables with up to a level of 20% (p ≤ 0.20) were selected for multiple analysis using Poisson Regression. The prevalence non-practice of PA during the pandemic was of 56.8% among college students. Variables, such as being with a partner (PR=1.28), presence of respiratory diseases (PR=1.17), negative self-perception of health (PR=1.37), increased consumption of ultra-processed foods (PR=1.29), and presence of depression (PR=1.21), showed statistically significant associations with the practice of physical activity. We concluded that the non-practice of PA in university students during the social isolation caused by the COVID-19 pandemic is associated with marital status, presence of respiratory diseases, negative self-perception of health, increased consumption of ultra-processed foods, and presence of depression.Association of sex and training phase with physical activity and sedentary behavior in nursing students10.1590/1980-0037.2023v25e903702023-01-13T19:36:02.794000Z2020-08-09T06:49:00.307000ZMussi, Fernanda CarneiroSouza, Eliane Barbosa deSilva, Fernanda Michelle Santos ePitanga, Francisco José GondimPatrão, Ana LuísaCampos, Ana Clara Paixão

Abstract Physical Insufficient levels of physical activity and sedentary behavior are highly prevalent worldwide and associated with cardiometabolic diseases and may vary according to gender and academic training. The objective was to investigate the association of sex and academic training with the level of physical activity and time spent in sedentary behavior in nursing students. It is a cross-sectional study with 286 nursing students from a public university. A sociodemographic and academic characterization instrument and an extended version of the International Physical Activity Questionnaire were applied. Data were analyzed descriptively and by Pearson's Chi-Square/Fisher's Exact test. The significance level was 5%. 65.7% of university students were active. Men were more active in leisure (p=0.000) and commuting (p=0.03). There was no association between sex and semester and total physical activity level. The prevalence of time in sedentary behavior ≥ 8 h/day for seven, five days, and weekends were 39.3%, 57.1%, and 21.4% for men and 55.0%, 65.1%, and 43.0% for women. A more significant proportion of women showed time in sedentary behavior ≥ 8 h/day on weekends (p=0.015) than men. A higher proportion between the 1st and 5th semesters remained ≥ 8 h/day in sedentary behavior on seven (p=0.024) and five days (p=0.001) week compared to those between the 6th and 10th semesters. The prevalence of insufficient physical activity levels and a long time in sedentary behavior were high and influenced by gender and training phase. Men were more active in commuting and leisure than women. Sedentary behavior is associated with gender and a training phase.The influence of overweight on postural balance and mobility of candidates for bariatric surgery10.1590/1980-0037.2023v25e908052023-01-13T19:36:02.794000Z2020-08-09T06:49:00.307000ZSilva, Bárbara Amaral BrunoSantos, José Cristiano Faustino dosCavalcanti, Thaurus Vinicíus Oliveira deCosta, André dos SantosCarvalho, Paulo Roberto Cavalcanti

Abstract Obesity is considered a risk factor to health and besides generating metabolic and cardiovascular alterations, it is related to mechanical complications. Since stability may be altered due to anthropometric and biomechanical factors, studies investigating the relationship of excess weight on the mobility and balance of obese adults are still scarce. The research aimed to evaluate the postural balance and mobility of obese individuals who are waiting for bariatric surgery. This is a cross-sectional and descriptive study, conducted at the Hospital das Clínicas of the Universidade Federal de Pernambuco. The sample consisted of 97 individuals, 81 women, 16 men, age 38.39 ± 10.60 years and body mass index 47.5 ± 6.9 kg/m2. The Timed Up and Go test, which evaluates the mobility, resulted in 7.6 ± 1.7 seconds as the average of the longest times spent to perform the test. Regarding the evaluation of dynamic balance and mobility, it was found that the domains of anticipatory postural adjustments, necessary to prevent postural disturbances (median 5, 95%CI 5-6) and the domain of dynamic movement, which corresponds to the balance necessary to walk (median 8, 95%CI 7-9) are the most impaired in the subjects with obesity. Positive correlations were found between weight and dynamic balance. The findings indicate that excess body fat interferes with dynamic balance.Do gender and type of sport matter in the association between basic psychological needs satisfaction and life skills development?10.1590/1980-0037.2023v25e909802023-01-13T19:36:02.794000Z2020-08-09T06:49:00.307000ZFreire, Gabriel Lucas MoraisQuinaud, Ricardo TeixeiraSantos, FernandoOliveira, Daniel Vicentini deFiorese, LenamarXavier, Sherdson Emanoel da SilvaNascimento Junior, José Roberto Andrade do

Abstract This study examined how basic psychological needs satisfaction can predict youth participants’ life skills development according to gender and sport type. A sample of 461 Brazilian youth sport participants (325 boys and 136 girls) ranging between 10 and 17 years was included. Data collection was conducted through the Life Skills Scale for Sport and Basic Needs Satisfaction in Sport Scale. Overall, the three subscales of basic psychological needs satisfaction explained a significant amount of the variance in eight life skills (R2 range = .02 to .08 p < .05) and total life skills (R2 = .07; p < .001) in male athletes. Concerning female athletes, multiple regression analyses revealed significant variance only for teamwork (R2=.09; p<.01) and goal setting (R2= .06; p<.05). Regarding the type of sport, the model presented a significant amount of the variance in eight life skills (R2 range = .02 to .05 p < .05) and total life skills (R2 = .08; p < .001) in team sports. Lastly, in individual sports, multiple regression analyses revealed significant variance only on goal setting (R2= .04; p<.05). Findings showed that youth sport coaches could focus on youth participants’ basic psychological needs when trying to foster life skills development across sport contexts. Based on these findings, several suggestions for improving future research and practice in this area are presented.Agreement and reproducibility of a portable electrical impedance myography device for body fat percentage estimation in normal weight men and women10.1590/1980-0037.2023v25e924582023-01-13T19:36:02.794000Z2020-08-09T06:49:00.307000ZRibeiro, Josiel GomesRossato, MateusOrssatto, Lucas Bet da RosaPicanço, Luhan Ammy AndradeSilva, Diego Augusto SantosBezerra, Ewertton de Souza

Abstract The aim of this study was to investigate the agreement and reproducibility of a portable electrical impedance myography device (EIM - SKULPT®) for body fat percentage (BF%) estimation in young adults. Sixty young adults volunteered for the study (women, n=30, 25.0±7.7 years; 21.5±1.9 kg/m2; and men, n=30, 21.6±6.3 years; 22.5±1.8 kg/m2). Participants underwent air displacement plethysmography (ADP) and EIM measurements for agreement analysis. EIM was performed three times on the same day for the within-day reproducibility analysis. Seven days later, 37 participants repeated the EIM measurements for the between-days reproducibility analysis. Comparisons of EIM and ADP methods, and EIM repeated measurements were performed with the paired T-test or one-way ANOVA repeated measures, the Bland-Altman plot, and simple linear regressions. BF% was higher (p<0.05) when estimated by EIM (19.91 ± 5.70 for men, and 30.77 ± 5.89 for women) compared to ADP (15.28 ± 5.66 for men, and 27.31 ± 5.98 for women). The Bland-Altman analysis presented a bias of 4.4% (95%CI=-3.4–12.2) and linear regression presented an R2=0.78. For between-days reproducibility, EIM means did not differ (25.33±7.69 and 24.94±8.30, p=0.890). Thus, while the EIM device exhibited high reproducibility of BF% estimates, caution should be exercised when comparing the results with other techniques for measuring BF%. The EIM device overestimated BF% compared to ADP. However, the EIM measurements presented very good within-day and between-days reproducibility and, thus, the EIM device can be used for longitudinal monitoring of BF%.Different kinesio taping tensions present similar benefits for postural control, dynamic balance, agility and instability sensation in individuals with chronic ankle instability: randomized clinical trial10.1590/1980-0037.2023v25e948132023-01-13T19:36:02.794000Z2020-08-09T06:49:00.307000ZOliveira, Gustavo Felipe Marques deStocco, Marieli RamosMacedo, Christiane de Souza GuerinoMachado, Felipe Vilaça CavallariOliveira, Márcio Rogério deAndraus, Rodrigo Antonio Carvalho

Abstract Ankle sprain is the most common injury in the lower limbs of physically active individuals, and one of its complications is chronic ankle instability (CAI), for which Kinesio Taping (KT) can be an alternative treatment. The aim of this study was to compare two treatment protocols with KT at different tensions on postural control, dynamic balance, agility and instability in individuals with chronic ankle instability. This is a randomized clinical trial in which postural control was evaluated through the force platform, agility by the side Hop Test, dynamic balance by the modified Star Excursion balance Test, and application of the Cumberland Ankle Tool Instability and Foot and Ankle Outcome Score to assess self-reported instability and functional instability. An initial assessment was conducted, followed by 5 weeks of intervention with weekly applications of KT, and one week after the completion of the intervention, a reassessment was performed. 21 participants were distributed to the group KT with tension (KTT: n=11) and the group KT without tension (KTWT: n=10). KT improves postural control (anteroposterior velocity: p=0.006 and mediolateral: p<0.001; anteroposterior frequency: p<0.001 and mediolateral: p=0.043 of the area of the center of pressure), dynamic balance (p< 0.001), agility (p=0.001) and feeling of instability in individuals with ICT (p=0.001) for both groups. Only one variable, sports category of the FAOS-FOOT questionnaire showed significant change (p=0.008). KT, with or without tension, is able to improve postural control, balanced balance, postural control, and feelings of instability in young adults with ICT.Anthropometric characteristics and physical activity level of Orienteers: a pilot study10.1590/1980-0037.2023v25e951022023-01-13T19:36:02.794000Z2020-08-09T06:49:00.307000ZSilva, Vladimir Schuindt daSouza, IsraelRieger, Eraci DrehmerIbáñez, Héctor EsteveVieira, Filomena

Abstract The present study aimed to describe a study protocol for Orienteers’ anthropometric characteristics and physical activity level. This is an individualized, observation and cross-sectional pilot study, that has encompassed three Orienteers (2 Portuguese men and 1 Spanish woman) with mean age 22.6 ± 3.78 years and 8.0 ± 2.64 consecutive years of Orientation practice. In total, 26 anthropometric variables were assessed: four basic measurements, nine skinfolds, nine girths and four breadths; Body Mass Index was calculated, as well as body composition and somatotype (according to the Heath-Carter method). The International Physical Activity Questionnaire – Short Form was used to obtain the score expressed as metabolic equivalent and the energy expenditure in kilocalories, both during the reference week. Mean somatotype recorded for Orienteering athletes could be defined as balanced mesomorph. Scores recorded for different physical activity/ inactivity expressed domains have shown high-energy expenditure. Sports Science Professionals can use the herein proposed protocol to improve Orienteers’ training.Body posture and the state of mood in women10.1590/1980-0037.2023v25e958622023-01-13T19:36:02.794000Z2020-08-09T06:49:00.307000ZSilva, Mayara Miranda daSantos, Ana Maria Pujol Vieira dosArossi, Guilherme Anziliero

Abstract In the clinical practice of health professionals, it is observed that body posture can reveal the current emotional state. Emotional states can generate habitual gestures and postures that continue even after the emotion has ceased. The objective was to identify postural changes and variables found in the mood state in women. After project submission and approval to the CEP of the Lutheran University of Brazil (ULBRA), 15 women with a mean age of 39.6 years, regardless of color, race, or social class participated in the study. The sample was by convenience, being recruited through invitations on social networks. The research was carried out at the Walk Clinic of Exercise, in Charqueadas/RS. The instruments used were a sociodemographic and clinical questionnaire to characterize the sample, the Brunel Mood Scale (Brums), and the DIPA v13 (Digital Image based Postural Assessment) to assess posture. The results were presented in the form of descriptive statistics. It was found that increased tension and mental confusion for women with head changes in the sagittal plane and who also showed decreased vigor. In this study, it was verified that for women with low vigor, there is head alteration and that they present tension and mental confusion. More studies should be carried out with different methodologies in larger samples to enable the mapping and delineation of most postural changes related to emotional states and mood disorders, with due application in the clinical practice of health professionals.Physical load and heart rate behavior in workers in the slaughterhouse and meat packing industries10.1590/1980-0037.2023v25e935772023-01-13T19:36:02.794000Z2020-08-09T06:49:00.307000ZSantos, Lorena AltafinVanderlei, Luiz Carlos MarquesGarrigou, AlainPasquereau, PierrickMessias, Iracimara de Anchieta

Abstract High physical overload during the workday and some conditions present in the workplace can generate several losses in the worker’s health. The use of tools capable of identifying physical load (PL), such as heart rate (HR) analysis, is essential. The aim of the study was to evaluate the physical load and heart rate behavior of workers in the slaughterhouse. The cardiovascular load reached by two individuals was 12% and 24%. In relation to the PL rating, they fit as moderately heavy to heavy work. The HR, was higher at the end of the work when compared to the beginning. Furthermore, it was pointed out that the temperature, noise, and body mass index were above normality values. The physical workload was classified as moderately heavy to heavy. The limit HR was reached in some moments of the work by one of the workers and two of them reached higher HR values at the end of the work.Evaluation of the effect of physical exercise interventions in Primary Health Care in Brazil on cardiometabolic risk factors: a systematic review10.1590/1980-0037.2023v25e868762023-01-13T19:36:02.794000Z2020-08-09T06:49:00.307000ZBrunheroti, Karina de AlmeidaBrito, Bruna Thais Gomes deSilva, Ana Flávia Andalécio Couto daCastro, Gabriela Lima deViana, Rebeca Baptista FonsecaBarbosa, Luis FabianoPuga, Guilherme MoraisAndaki, Alynne Christian RibeiroPapini, Camila Bosquiero

Abstract The objective was to systematically search and synthesize the evidence available in the literature about the effect of physical exercise interventions Primary Health Care (PHC), carried out in Brazil, on cardiometabolic risk factors. The search was performed in the PubMed, Virtual Health Library and Web of Science databases. The inclusion criteria were: studies with physical activity (PA) interventions or exercise in PHC; carried out in Brazil; population aged >18 years; at least one cardiometabolic risk factor assessed pre and post-intervention. The “Health Sciences Descriptors” were used to define the search descriptors: “physical activity” OR “exercise” OR “motor activity” AND “primary health care” OR “health centers” OR “primary care” AND “Brazil”. The selection phases were performed by pairs of blinded researchers and the conflicts were decided by a third evaluator. Jadad scale was used to assess the methodological quality of the articles included. In total, 1,817 articles were found and 26 duplicates excluded, leaving 1,791 for reading of titles. The abstracts of 105 articles were read, and 53 articles were read in full. Finally, 06 articles were considered eligible and included in the review. The cardiometabolic risk factors evaluated in the included studies were body mass index (4 studies), waist-hip ratio (1 study), fat percentage (1 study), blood pressure (2 studies), lipid profile (1 study), inflammatory profile (1 study), and aerobic capacity (3 studies). It is concluded that there is insufficient evidence in the literature about the effect of exercise interventions in PHC with a focus on cardiometabolic risk factors.Physical activity on anxiety symptoms during the COVID-19 pandemic: a systematic review10.1590/1980-0037.2023v25e917152023-01-13T19:36:02.794000Z2020-08-09T06:49:00.307000ZDavid, Iaggo RaphaelBarbosa, Elizabete de OliveiraFelício, Laís Francielle FranciscaLeao, Luana LemosSouza, Eric Hudson Evangelista ePaula, Alfredo Maurício Batista deSilva, Felipe de OliveiraMachado, Frederico Sander MansurMonteiro-Junior, Renato Sobral

Abstract This systematic review aimed to investigate the effect of physical activity on anxiety symptoms during the COVID-19 pandemic. Three databases (PubMed; Scopus and Web of Science) were searched in the period from 2020 to 2022 the following base terms were used: “Physical Activity”, Exercise, Anxiety and COVID-19. Peer-reviewed, primary studies published in English, Portuguese and Spanish using valid and reliable measures were included. Eighteen studies met the eligibility criteria, of which 17 were cross-sectional, 2 were cohort studies. The number of participants ranged from 43 to 2,301, aged between 18 and 65 years or older. A decrease in PA practice or an increase in sitting time were associated with higher levels of anxiety symptoms. Additionally, participants who did not meet PA recommendations were more likely to experience moderate to severe anxiety symptoms. The results showed that physical activity is associated with the alleviation of anxiety symptoms during confinement in the COVID-19 pandemic.Biological, physical fitness and motor coordination profile and its associations with the performance of practitioners of rhythmic gymnastics at sports initiation: a systematic review10.1590/1980-0037.2023v25e923472023-01-13T19:36:02.794000Z2020-08-09T06:49:00.307000ZSampaio, Daisy FernandesBorges, Marcelo GulesRibas, Michele Caroline de Souza

ABSTRACT Describing the biological, physical fitness and motor coordination profile and its possible associations of these variables with the performance on rhythmic gymnastics (RG) of practitioners of sports initiation. Systematic search of articles carried out from the 20th to the 23rd of July, 2022, on three databases: 1) PubMed; 2) SportDiscus and 3) Google Scholar. The search was conducted through an advanced research tool, from the constructing of descriptors and keywords related to the theme. The selection of descriptors and keywords was performed through consensus of published sources (original and of systematic review articles) and inserted in English language in each database. 10 articles were included in the descriptive summary of data. The greatest part of these studies is of female practitioners, having the data collection in its majority in the European region. The profile of beginner gymnasts was characterized by low values for BMI, BF%, high values for stature, high indexes of flexibility, explosive strength, motor coordination and balance. Flexibility, explosive strength, muscular endurance and high levels of motor coordination were the variables which most presented positive associations with the performance on RG. The values of body mass and skin folds presented a predictive negative power on the success of RG movements. The impact of different variables on the beginner gymnasts’ performance evidences the necessity of working physical and motor components in a way that it supports the objects of development of each practitioner considering the biological, physical and motor aspects.Validity, reliability and measurement error of quadriceps femoris muscle thickness obtained by ultrasound in healthy adults: a systematic review10.1590/1980-0037.2023v25e939362023-01-13T19:36:02.794000Z2020-08-09T06:49:00.307000ZSoares, André Luiz ConvenienteCarvalho, Ramon FrancoMogami, RobertoMeirelles, Cláudia de MelloGomes, Paulo Sergio Chagas

Abstract Due to its low cost and operational simplicity, ultrasound has been used to monitor muscle thickness in laboratory environments, rehabilitation clinics, and sports clubs. However, it is necessary to determine the measurement's quality to infer whether the possible changes observed are derived from the treatment or the measurement error. Therefore, we performed a systematic review to determine the validity, reliability, and measurement error of quadriceps femoris muscle thickness obtained by ultrasound in healthy adults. A search was conducted in the Pubmed, Scopus, and Web of Science databases until April 2022. The study selection process was carried out by two independent researchers, with the presence of a third researcher in case of disagreements. Twenty-six studies were eligible for the review, being 4 of validity, 4 of reliability only, and 18 of reliability and measurement error. The intraclass correlation coefficient ranged from 0.60 to 0.99 in validity studies and from 0.44 to 0.99 in reliability studies. The typical error of measurement ranged from 0.01 to 0.47 cm, and the coefficient of variation was from 0.5 to 17.9%. Four studies received “very good” classification in all the risk of bias analysis criteria. Therefore, it is concluded that the quadriceps femoris muscle thickness obtained by ultrasound was shown to be valid, reliable, and to have low measurement errors in healthy adults. The weighted average of the relative error was 6.5%, less than typical increases in resistance training studies. The raters' experience and methodological care for repeated measurements were necessary to observe low measurement errors.Shedding light on tactical performance and tactical behavior concepts with a particular reference to soccer10.1590/1980-0037.2023v25e915502023-01-13T19:36:02.794000Z2020-08-09T06:49:00.307000ZPraça, Gibson Moreira

Abstract Tactical aspects play a significant role in soccer, as a team sport, considering the inherent unpredictability of the actions during a game. Therefore, measuring tactical variables is essential for training planning in soccer and other team sports. However, previous studies have interchangeably used the terms “tactical behavior” and “tactical performance” to refer to the collected variables, which has become a source of questioning in recent literature. In this point-of-view article, the tactical behavior and tactical performance concepts are defined, discussed, and exemplified based on previous studies. While tactical behavior measures are associated with descriptions of the actions, tactical performance variables are assumed to classify and interpret such behaviors considering reference values. Finally, examples of instruments for collecting each data are provided.
