Physical activities practicing among scholar professors: focus on their quality of life

Objective: To investigate the practice of physical activity among scholar professors focusing on their quality of life. Methods: A cross-sectional study was carried out with 121 professors at one of the campuses of a state university in the State of Paraná, using a questionnaire created by Baecke and adapted for the study. Results: The analyzed group presented a level of inadequate physical activity of 54.4%, with mean body mass of 26.20, considered overweight. Conclusion: The study indicated that professors do not practice physical activity at the level recommended by the World Health Organization; therefore, they are, for the most part, sedentary and have complaints of anxiety. It is advisable to carry out actions aimed at the health of the professors, directed to the modification in the lifestyle, with regular practice of physical activities and balanced diet, for the improvement of the quality of life.


INTRODUCTION
Physical activity, understood as any body movement produced by the skeletal muscles resulting in energy expenditure higher than rest, 1 encompasses activities in various contexts, such as leisure, transportation, domestic tasks and work. 2 Physical inactivity is one of the main determinants of chronic non-communicable diseases, causing one in ten deaths worldwide. 3In the context of disease prevention, physical activity plays a major role in the prevention of Metabolic Syndrome (MS), which is characterized by the presence of at least three of the following risk factors: abdominal adipose, hypertriglyceridemia and low concentration of high density lipoprotein (HDL-C), elevated triglycerides, high blood pressure and elevated glucose. 4,5he World Health Organization (WHO) establishes as ideal for adults the practice of at least 150 minutes per week of moderate physical activity (PA) or 75 minutes per week of vigorous PA, in sessions of at least 10 minutes duration, without determination of weekly frequency. 6In a study carried out in Minas Gerais, physical activity was classified as follows: ideal, if practiced, at least 150 minutes/week; between 1 and 149 minutes per week; and poor if there is no moderate or vigorous physical activity. 6,7ata reveal that 17% of the world population is considered physically inactive and 60% do not correspond to the minimum of advisable physical activity. 8,9Sedentary life affects approximately 70% of the world population, being considered by WHO the main responsible for 2,000,000 deaths per year worldwide and for 75% of deaths in the Americas. 8t is worth noting that the high levels of physical inactivity are associated with the contemporary style of life of the people, having as determinants the obligations and needs related to work, use of motorized transportation and preference for leisure activities related to electrical and electronic equipment such as television, computers and video games. 10It is also observed that the work areas related to safety and education, in which professors are inserted, are the most affected and most present behaviors that can be detrimental to health. 5,10he influence of working conditions on workers' health occurs due to inadequate behaviors that can be caused by the labor universe, with sedentarism being one of the recurring problems among several professionals, and among them the professors, due to their long stressful daily activities, associated with lack of regular physical activity during leisure time. 11tudies show that lack of physical activity is also directly associated with high rates of overweight in higher education professors, and is accentuated by inadequate eating habits, alcohol use and high levels of stress. 12,13Work and study commitments are among the main barriers to the practice of physical activities among professors. 13erloading and inadequate working conditions, coupled with pressure to achieve productivity goals, result in high levels of stress and lack of regular physical activity. 14,15onsidering the relevance of the practice of physical activity for the welfare and quality of life of teaching professionals, the present study was delineated through the following research question: "Do you practice physical activity with the objective of improving your quality of life?" Finding the key in question may provide significant data for the construction of intervention programs with the teaching staff of the higher education institution.Therefore, the objective of the present study was to investigate the practice of physical activities of university professors focusing on quality of life.

METHODS
This is a transversal research using quantitative approach, developed in one of the seven campuses of a public university in the state of Paraná.The institution has a total of 68 undergraduate courses, of which 38 are bachelor's degrees and 30 are bachelor's degrees.The general teaching staff consists of 686 professionals, distributed in the various campuses.The campus that will be the focus of this research covers 11 courses, distributed in the morning, afternoon and evening shifts that are served by 177 professors.
The sample consisted of 121 professors, who make up the centers of human sciences and education, applied social sciences and health sciences, which, for the most part, have an exclusive work regime.The inclusion criterion used was to be a full-time professor during the period of data collection, and the exclusion criterion was to be on leave of any type or absent due to qualification processes.The sample was determined by means of a sample calculation, which considered the number of the total population (n = 177), the unknown prevalence of physical inactivity of the population (50%), confidence level equal to 95% and sample error of 5%.10% of this value was added to the sample, providing for eventual losses and refusals, totaling 133 professors.
The instrument selected for data collection was the 'Brief Questionnaire for Measuring Standard Physical Activity in Epidemiological Studies', created by Baecke Burema and Frijters, adapted for the present study. 16he Baecke questionnaire is composed of 16 questions that cover three scores of Habitual Physical Activity (HPA) of the last 12 months: 1) occupational physical activity score, with eight questions; 2) physical exercise in leisure time score (PEL), with four questions; 3) leisure and locomotion physical activity score (LLA), with four questions.
In the present study, the questions of the occupational physical activity scores and the questions of physical activities of leisure and locomotion were used, as well as the records of the anthropometric indices of height and weight of the professors, which were used to calculate the Body Mass Index (BMI).

Quality of life of scholar professors
Dias J, Dusmann Junior M, Costa MAR, Francisqueti V, Higarashi IH Data collection was performed between May and July of 2016, at the institution's premises.The researcher was present at the institution for three days a week, alternating between the morning, afternoon and evening shifts, to fill out the questionnaire by the professors.The approach of the professors was done in the nursing laboratory, in the corridors of the institution and also in the collegiate classrooms.
The questionnaire was given to the professors after being accepted to collaborate with the research, demonstrated from the signing of the Informed Consent Term.The time required to complete the questionnaire ranged from 10 to 15 minutes for each professor, making the researcher available until the completion of the questionnaire, to resolve doubts, when necessary.
The data collected were stored in an Excel 2010 worksheet and the analysis was performed by means of descriptive statistics with mean values and standard deviation for the continuous variables and by absolute and relative frequencies for the categorical variables.

RESULTS AND DISCUSSION
The sample was composed of 121 faculty members at the university.Of the participants, 55 (45.5%) were male and 66 (54.5%) were female, ranging in age from 20 to 67 years, with a mean age of 44.4 years (Table 1).
It is noticed that the increase in the number of women in the labor market portrays a fact considered irreversible, and women professors sometimes accumulate more than one working shift: as health and/or educational professionals and as housewives.
This unfavorable situation reflects on their health, which can trigger a stress process, in addition to other health problems. 17egarding the anthropometric data, the average weight of the professors was 72.57kg and the average height was 168.28 cm.In relation to the number of days per week in which they practice physical activity, an average of 2.37 was presented (Table 2).The standard deviation of the group considered adequate for the body mass index has a mass of (14.60), height (9.68), BMI (3.99) and days of the week of Physical Activity (60).When compared to the inadequate, the mean of the inadequate group was (74.83), height (167.86),BMI (26.20) and days of the week of Physical Activity (2.81).The standard deviation of the inadequate group for the mass was (15.36), the stature of (8.74), the BMI (4.29) and days of the week of Physical Activity (2.01).
In this study, the BMI result showed certain equivalence between professors classified as eutrophic (46.8%) and overweight (36.9%), and the minority (16.2%) presented obesity (Table 2).It should be noted that the average number of days of the week that professors practiced physical activity did not exceed 3 (minimum of 2.37 and maximum 2.81 days).
Thus, insufficient levels of physical activity have been related to the excessive accumulation of body fat, negative modifications in the profile of blood lipids and high blood pressure levels. 18t is noteworthy that most of the professors surveyed (53.1%) presented overweight and obesity, which may represent a predominance of a risk profile for metabolic and cardiovascular diseases (Table 3).It is known that the practice of regular physical activity is a fundamental part for the precaution of several health problems, for its biopsychosocial benefits and besides being indispensable for full motor development. 19verweight is related to inadequate eating habits and lack of physical activity, which can lead to an increase in blood pressure levels and lead to high levels of stress.It is believed that the risk of stroke is doubled in stressed workers and that 32.5% of myocardial infarctions are influenced by psychosocial aspects, including stress and anxiety. 18,19uality of life at work (QWL) is related to stress concerns and ways of avoiding it, seeking work satisfaction and fulfillment, as well as preserving mental health in the work environment. 20hus, it is observed that the maintenance of healthy habits, such as the practice of physical activity, constitutes one of the attitudes that can contribute to an improvement in the quality of life of individuals, as well as in the prevention of diseases such as obesity and stress, promoting individuals' health. 20orporal practices, physical activity, physical exercises and sport practice are linked to the improvement of the quality of life.However, there is no conceptual clarity or even an exact pathway to such practices and their relationship to quality of life. 21hen assessing the level of physical activity based on the weekly frequency with which this activity is performed, the results showed that 45.6% were classified with an adequate level and 54.4% inadequate (Table 4).physical activity predisposes these professionals to muscular weakness, possibility of muscular fatigue and difficulty to endure the long hours of weekly work, with predisposition to work away from work due to occupational diseases.Among the causes of absenteeism are the psychobiological disorders, for they negatively influence professors' working capacity and, consequently, students' learning.This situation is in contrast to an intense work pace, which requires high levels of attention and concentration, necessary for the good performance of teaching activities. 22,23n a study with professors, physical inactivity was prevalent in 79.7% of the professors, who were linked to the variables: female individuals, older and with lower socioeconomic status. 23he level of physical activity in professors of upper public state education oscillates according to the age of each professor.The predominance of insufficient levels of physical activity was 46.3% in professors, with a predisposition to decrease physical activity with increasing age. 23hysical inactivity is a major public health problem, and 70% of the adult population does not reach the minimum levels of physical activity recommended by the WHO, which contributes to the increase of morbidity and mortality associated with cardiovascular diseases. 24 contemporary report on the global burden of disease has shown that factors such as inadequate diet, hypertension, high BMI, smoking, high fasting glucose and inactivity, in this order of importance, are of the highest magnitude for the cause of death and for the years of life adjusted due to disability in the Brazilian population. 25hese results may help in the recognition that healthy habits remain precarious among the population, even among the most enlightened individuals.Thus, public health policies should prioritize actions for health promotion and disease prevention.
The present study presents as a limitation the fact that it was developed only with the professors of one of the campuses of The practice of physical activity is considered one of the main factors for a healthy life, and its absence is consequently seen as a risk factor for the health of the population, accounting for 6% of global mortality. 21The incorporation of an active lifestyle is a very important condition for the preservation/maintenance of health status.
A study carried out in Santa Catarina with physical education professors showed that, in the overall lifestyle, professors had positive values ranging from 41.6% to 84.8% in the investigated dimensions, highlighting the active lifestyle, with 57.6%, which was evaluated in the study as a positive behavior in terms of quality of life. 19,20he research conducted in southern Brazil, where 46.5% of professors did not perform programmed physical activity, justified by lack of time, double working hours and socioeconomic issues corroborates these findings. 21,22It is worth noting that lack of Quality of life of scholar professors Dias J, Dusmann Junior M, Costa MAR, Francisqueti V, Higarashi IH the institution, as well as the lack of policies aimed at physical activities and their respective applicability in the daily life of the educational institution.
The result of this research provides information that can trigger a planning and direction of actions to the university professors, guaranteeing the possibility of greater adhesion and incentive to practice physical activities as a way of improving the health and quality of life of the teaching staff.Therefore, it is necessary to carry out the research in the other campuses of the university, in order to detect the quality of life of professors and develop strategies throughout the university.

CONCLUSIONS
The study showed that the large number of professors presented physical activity at levels inadequate to have a good quality of life, and more than half of the professors are at risk, such as overweight and/or obesity.In this way, intervention mechanisms must be thought early, aiming at the continuous health of professors.The first attitude to be taken concerns strategies that seek a lifestyle change centered on regular physical activity and a balanced diet.
In this perspective, the incentive of the practice of physical activity for professors should be stimulated through programs that offer a routine of physical activities and a balanced diet in the work place, besides the awareness in terms of the reduction of the time spent in hypokinetic activities, such as watching television and using computer for long periods of time.
Analyzes were carried out by means of the Statistical Package for Social Science (SPSS), version 20.0.The research complied with the requirements of Resolution No. 466/2012 of the National Health Council, and was approved by the Committee of Ethics in Research with Human Beings of the State University of Maringá, under the opinion nº 1,625,229.This research is part of the Worker's Health Program, which is being developed at the institution of higher education.
