EFEITOS DO TREINAMENTO DE BASQUETEBOL E FUTEBOL SOBRE A RIGIDEZ ARTERIAL

EFECTOS DEL ENTRENAMIENTO DE BÁSQUETBOL Y FÚTBOL SOBRE LA RIGIDEZ ARTERIAL

ABSTRACT

Objective

The purpose of this study was to examine arterial stiffness in elite basketball and soccer athletes by pulse wave velocity.

Methods

The cohort comprised 35 healthy male volunteers aged 17 to 26 years. All the subjects were either basketball players (n=9), soccer players (n=12) or sedentary controls (n=14). Arterial stiffness was measured by the Pulse Trace System (Micro Medical Ltd., Rochester, UK) and echocardiographic images were taken using a commercially available machine (Vivid 7 GE-Vingmed, Horten, Norway) with a 2.5 MHz transducer.

Results

The basketball players had significantly higher heights and body weights as compared to both the soccer players and the controls. The aortic elastic properties derived from the echocardiographic measurements did not differ between the groups. The peripheral pulse wave velocity measurements showed significantly lower values both in the basketball and soccer players compared to the controls, whereas the central pulse wave velocity measurement was significantly lower only in the basketball players as compared to the controls. No significant difference was seen between the basketball and soccer players.

Conclusions

The results of this study show that football and basketball exercises comprised of aerobic, anaerobic, endurance balance-coordination and sport-specific training play a role in reducing arterial stiffness. Level of evidence I; type of study: prognostic study.

INTRODUCTION

Diseases of the cardiovascular system (CVS) are one of the top causes of mortality everywhere in the world. Formation of atherosclerosis in the vessels can be genetic, environmental, nutrition/diet and exercise-related and it is known that atherosclerotic process in the vessels results in stiffness in the arterial vessels.11.Green DJ, Maiorana A, O’Driscoll G, Taylor R. Effect of exercise training on endothelium-derived nitric oxide function in humans. J Physiol. 2004;561(Pt 1):1–25. Arterial stiffness measurements are used as an early indicator for asymptomatic atherosclerosis and CVS risk.22.Safar ME, London GM. Therapeutic studies and arterial stiffness in hypertension: recommendations of the European Society of Hypertension. The Clinical Committee of Arterial Structure and Function. J Hypertens. 2000;18(11):1527-35. Arterial pulse wave velocity (PWV) is widely used as a gold standard for the non-invasive assessment of arterial stiffness. Studies report that regular physical activity reduces stiffness, whereas a sedentary lifestyle increases stiffness.33.Horta BL, Schaan BD, Bielemann RM, Vianna CA, Gigante DP, Barros FC, et al. Objectively measured physical activity and sedentary-time are associated with arterial stiffness in Brazilian young adults. Atherosclerosis. 2015;243(1):148-54. Several studies also provide evidence of reductions in central arterial stiffness with endurance training in both young and older populations and in competitive endurance athletes.44.Cameron J, Dart A.

The purpose of this study was to examine the arterial stiffness of elite ball sports’ athletes by pulse wave velocity.

MATERIALS AND METHODS

The cohort comprised 35 healthy male volunteers, ages 17 to 26 years ( Table 1 ). All subjects were basketball players (n = 9), soccer players (n = 12) or sedentary controls (n = 14). All of them were non-obese (BMI < 30 kg/m2), non-smoking, normotensive (< 140 / 80 mmHg), normolipidemic, and free of cardiovascular and other chronic diseases such as diabetes mellitus, chronic renal disease, peripheral arterial disease, alcohol addiction, history of vascular surgery, arrhythmia, cardiac valvulopathy or myocardial ischemia according to medical history, and clinical and electrocardiographic evaluation. None of the subjects was taking anti-diabetic or cardiovascular-acting medications and antioxidants or lipid-lowering supplements. Physical activity and nutrition habit was documented by questionnaire.

Table 1
Physical characteristics of athletes and controls. (Data are mean ± SD).

Subjects in group 1 (basketball players, n = 9) were athletes undergoing training 15 hours per week for the last 12 months. The training was comprised of 6 hours of specific basketball training, 5 hours of aerobic / endurance activities, 2 hour of strength training, 1 hour of anaerobic dynamic training, and 1 hour of balance and coordination exercises. They have been playing for 6 years in average. Subjects in group 2 (soccer players, n = 12) were athletes undergoing training 19 hours per week for the last 12 months. The training was comprised of 7 hours of specific soccer training, 7 hours of aerobic/endurance activities, 2 hours of strength training, 2 hours of anaerobic dynamic training, and 1 hour of balance and coordination exercises. They have been playing for 7 years in average. Subjects in group 3 were sedentary (less than 1 hour physical activity per week, n = 14) and were matched with the other groups for age.

After being informed about the study and test procedures, and any possible risks and discomfort that might ensue, all subjects read and signed an informed-consent form approved by the University’s Institutional Ethical Board for Protection of Human Subjects (number: 382), which also approved the study.

Upon arrival at the laboratory, measurements for body mass and body fat were taken from each subject. Body fat was calculated by measuring sub-dermal fat content from 5 body areas (abdomen, sub-scapulae, triceps, lateral side of the thigh and lateral side of the abdomen) using a skin-fold caliper and body mass was recorded using standard laboratory scales. 20 m shuttle test was used to obtain VO2 max values.

The Pulse Trace System (Micro Medical Ltd., Rochester, UK) was employed to record central and peripheral arterial stiffness. Pulse Trace PWV uses the standard Doppler method to detect the onset of flow in the artery. This equipment has a 4 MHz Doppler probe for identifying the arrival of the arterial pulse. The transit time (ΔT) was computed from the foot-to-foot time difference in milliseconds between the two sequentially measured Doppler waveforms from the above mentioned locations using the ‘R’ wave of the ECG as a timing reference. The Pulse Trace PWV automatically detects the foot-to-foot of the waveform. The average of ten waveforms from each location is used and the SD is calculated and displayed. At each time point, the measurements were made three times for each individual subject and the mean value was recorded. For the measurements of central and peripheral arterial stiffness, the distance (D) between the carotid artery and brachial artery, and the distance between the carotid artery and femoral artery was measured using a measuring tape, respectively. PWV in m/sec is automatically calculated by dividing the time delay by the externally measured distance between locations (PWV = D / ΔT). All waveforms are displayed and the detected onset of the pulse is marked.

Images were obtained by a commercially available machine (Vivid 7 GE-Vingmed, Horten, Norway) with a 2.5 MHz transducer. All patients were examined at rest while in the left lateral recumbent position following the recommendations of the American Society of Echocardiography images were obtained in the parasternal long and short axis and in the apical four and five chamber views using two dimension and M-Mode Doppler.1717.Lang RM, Bierig M, Devereux RB, Flachskampf FA, Foster E, Pellikka PA, et al. Recommendations for Chamber Quantification: A report from the American Society of Echocardiography’s Guidelines and Standards Committee and the Chamber Quantification Writing Group, Developed in Conjunction with the European Association of Echocardiography, a Branch of the European Society of Cardiology. J Am Soc Echocardiogr. 2005;18(12):1440-63. All of the measurements were digitized at the peak of the R wave by the average of 3 cardiac cycles. The ascending aorta was recorded in the two-dimensional guided M-Mode tracings. Aortic diameters were recorded 3 cm above the aortic valve. Aortic systolic diameter was determined at the time of the full opening of the aortic valve, and aortic diastolic diameter was determined at the peak of QRS. Blood pressure was measured simultaneously from the right brachial artery with an aneroid sphygmomanometer. Korotkoff phases I and V of the measurements were used to determine the systolic and diastolic blood pressure.

1. Aortic strain (AS) was calculated as follows:1818.Stefanadis C, Stratos C, Boudoulas H, Kourouklis C, Toutouzas P. Distensibility of the ascending aorta: comparison of invasive and non-invasive techniques in healthy men and in men with coronary artery disease. Eur Heart J. 1990;11(11):990-6.

A S = ( A O S A O D ) / A O D ( A O S =  systolic aortic diameter and  A O D =  diastolic aortic diameter) 

2. Aortic distensibility (AD) was calculated as follows:1818.Stefanadis C, Stratos C, Boudoulas H, Kourouklis C, Toutouzas P. Distensibility of the ascending aorta: comparison of invasive and non-invasive techniques in healthy men and in men with coronary artery disease. Eur Heart J. 1990;11(11):990-6.

A D = 2 X ( A O S A O D ) / [ A O D X ( S B P D B P ) ] . ( S B P =  systolic blood 

3. Aortic stiffness index (beta stiffness index, BSI) was calculated as follows:1818.Stefanadis C, Stratos C, Boudoulas H, Kourouklis C, Toutouzas P. Distensibility of the ascending aorta: comparison of invasive and non-invasive techniques in healthy men and in men with coronary artery disease. Eur Heart J. 1990;11(11):990-6.

B S ∣= ln ( S B P / D B P ) / [ ( A O S A O D ) / A o D ] . ( S B P =  systolic blood   pressure and DBP=diastolic blood pressure) 

Statistical analysis was performed using SPSS version 16.0 (SPSS, SPSS Inc, Chicago, Illinois, USA) software. For comparison among the groups, one-way analysis of variance (ANOVA) was used. Scheffe’ post hoc test was performed to evaluate a significant F-value. All measurements are expressed as mean ± SD. All tests were two-tailed and the level of significance was set at p < 0.05.

RESULTS

Demographic and physical characteristics of the study groups are shown in Table 1 . Basketball players had significantly higher height and body weight as compared to both soccer players and controls (p < 0.001 - 0.05). Heart rate was significantly reduced in basketball players than only in the control group (p < 0.05). As indicated in Table 2 , aortic elastic properties derived from echocardiographic measurements did not differ between the groups (p < 0.05). On the other hand peripheral pulse wave velocity measurements reflected significantly lower values both in the basketball (p < 0.001) and soccer players (p < 0.05) compared to controls, whereas central pulse wave velocity measurement was significantly lower only in basketball players (p < 0.05) as compared to controls ( Table 3 ). No significant difference was seen between basketball and soccer players (p > 0.05).

DISCUSSION

In our study aortic elasticity measured by echocardiography did not differ between the groups and were similar to many studies in literature. A study found an inverse relationship between increased aerobic performance capacity (VO2 max) and central arterial stiffness even in sedentary individuals.1919.Otsuki T, Maeda S, Iemitsu M, Saito Y, Tanimura Y, Ajisaka R, et al. Relationship between arterial stiffness and athletic training programs in young adult men. Am J Hypertens. 2007;20(9):967-73. The same study found that elderly individuals who performed endurance exercise had lower central arterial stiffness compared to more sedentary young individuals.99.Vaitkevicius PV, Fleg JL, Engel JH, O’Connor FC, Wright JG, Lakatta LE, et al. Effects of age and aerobic capacity on arterial stiffness in healthy adults. Circulation. 1993;88(4 Pt 1):1456-62. Otsuki et al. showed that central pulse wave velocity was lower in individuals with longer athletic/sports history (average 8 years) compared to those with shorter athletic history (average 5 years) in their study investigating the effect of short and long term sports activities on central arterial stiffness in short and long distance runners.1919.Otsuki T, Maeda S, Iemitsu M, Saito Y, Tanimura Y, Ajisaka R, et al. Relationship between arterial stiffness and athletic training programs in young adult men. Am J Hypertens. 2007;20(9):967-73. Kakiyama et al. stated that aerobic exercise performed at 70% VO2 max level for at least 60 minutes 3 - 4 days and 8 weeks duration cycling ergometry significantly reduced central PWV in young sedentary male subjects.55.Kakiyama T, Sugawara J, Murakami H, Maeda S, Kuno S, Matsuda M. Effects of short-term endurance training on aortic distensibility in young males. Med Sci Sports Exerc. 2005;37(2):267–71. In week 4 after the end of training (detraining effects) all these improvements were reversed which was why the authors underlined the need for continued exercise training.55.Kakiyama T, Sugawara J, Murakami H, Maeda S, Kuno S, Matsuda M. Effects of short-term endurance training on aortic distensibility in young males. Med Sci Sports Exerc. 2005;37(2):267–71. Currie et al. reported a 9% significant decrease in central pwv with an intensive endurance exercise composed of upper arm ergometer performed for as short as 6 days but at 65% VO2 max for 2 hours throughout 6 days (from 5.9 m / sec down to 5.4 m / sec).2020.Currie KD, Thomas SG, Goodman JM. Effects of short-term endurance exercise training on vascular function in young males. Eur J Appl Physiol. 2009;107(2):211-8. Hayashi at al. also showed that walking and jogging exercises performed at medium intensity (75% of heart rate reserve) for 16 weeks 2-3 days a week 45 minutes each day might significantly reduce central PWV in middle-aged sedentary individuals.2121.Koichiro Hayashi K, Sugawara J, Komine H, Maeda S, Yokoi T. Effects of Aerobic Exercise Training on the Stiffness of Central and Peripheral Arteries in Middle-Aged Sedentary Men. Jpn J Physiol. 2005;55(4):235–9. A recent meta-analysis summarizing the effect of regular aerobic or endurance exercise and a combination of both on central arterial stiffness proved the positive effects of aerobic exercise.2222.Li Y, Hanssen H, Cordes M, Rossmeissl A, Endes S, Schmidt-Trucksaess A. Aerobic, resistance and combined exercise training on arterial stiffness in normotensive and hypertensive adults: A review. Eur J Sport Sci. 2015;15(5):443-57. , 2323.Huang C, Wang J, Deng S, She Q, Wu L. The effects of aerobic endurance exercise on pulse wave velocity and intima media thickness in adults: A systematic review and meta-analysis. Scand J Med Sci Sports. 2016;26(5):478-87.

Both meta-analyses included studies that had investigated the effects of exercise on sedentary subjects. Huang et al. detected in a meta-analysis a 0.47 m / sec lower central PWV compared to controls following physical activity of medium intensity comprising walking and cycling exercises performed for 40 - 60 min/day, 3 - 5 days/week for 2 - 12 months by sedentary healthy or chronically diseased individuals.2323.Huang C, Wang J, Deng S, She Q, Wu L. The effects of aerobic endurance exercise on pulse wave velocity and intima media thickness in adults: A systematic review and meta-analysis. Scand J Med Sci Sports. 2016;26(5):478-87. Investigators underlined that aerobic exercise of longer duration would increase the effect according to the analysis results. In a meta-analysis Li at al. showed that a medium to high intensity walking and cycling exercise performed for 12 - 16 weeks, 3 days/week and 30 - 40 minutes/day significantly decreased central pwv (6.7 - 7.5%) in healthy sedentary individuals.2222.Li Y, Hanssen H, Cordes M, Rossmeissl A, Endes S, Schmidt-Trucksaess A. Aerobic, resistance and combined exercise training on arterial stiffness in normotensive and hypertensive adults: A review. Eur J Sport Sci. 2015;15(5):443-57. The analysis found a reduced pwv in both young (7.0%) and middle-advanced aged (6.7%) groups. Higher exercise intensity was associated with better pwv. In studies with athlete populations Nualmin et al. showed that arterial stiffness was lower in athletes who had been swimming and running 4 - 5 days/week for 9 years in average compared to sedentary individuals.1313.Nualnim N, Barnes JN, Tarumi T, Renzi CP, Tanaka H. Comparison of Central Artery Elasticity in Swimmers, Runners, and the Sedentary. Am J Cardiol. 2011;107(5):783-7. Knez et al. reported a lower central wave reflection in athletes that performed ultra endurance training 16 hours a week in average compared to less active athletes (who exercised 1 hour a week in average).1414.Knez WL, Sharman JE, Jenkins DG, Coombes JS. Central hemodynamics in Ultra-endurance athletes. J Sci Med Sport. 2008;11(4):390-5. In one of the very few studies with football players in literature Cioni et al. found a lower central pwv in soccer players with a play history of 4 years in average (5.87 m / sec) compared to the sedentary control group (6.62 m / sec).2424.Cioni G, Berni A, Gensini GF, Abbate R, Boddi M. Impaired Femoral Vascular Compliance and Endothelial Dysfunction in 30 Healthy Male Soccer Players: Competitive Sports and Local Detrimental Effects. Sports Health. 2015;7(4):335-40. They stated that elite soccer players had better central arterial stiffness. Again in one of the very few studies with basketball players in literature Ratgeber et al. did not find any difference in central pwv between 11 and 16 years young basketball players (5.82 m / sec) and age adjusted sedentary controls (5.83 m / sec).2525.Ratgeber L, Lenkey Z, Nemeth A, Hidvegi E, Husznai R, Verzar Z, et al. The effect of physical exercise on arterial stiffness parameters in young sportsmen. Acta Cardiol. 2015;70(1):59-65. The authors discussed that the young aortic wall was very elastic and increased blood pressure would not cause any stiffness of the aortic wall. Similarly, in our study basketball players who exercised regularly 15 hours in average per week for one year had lower central arterial stiffness values compared to sedentary controls. Soccer players who exercised 18 hours in average per week for one year had even lower arterial stiffness values although the difference was not significant. Long-term basketball training affects the carotid artery hemodynamically and stiffness drops during both rest and basketball training compared to sedentary controls.2626.Liu HB, Yuan WX, Qin KR, Hou J. Acute effect of cycling intervention on carotid arterial hemodynamics: basketball athletes versus sedentary controls. Biomed Eng Online. 2015;14(Suppl 1):S17.

Contrary to many studies showing a positive effect of aerobic exercise on central PWV the effect of the latter on peripheral PWV has been controversial.2121.Koichiro Hayashi K, Sugawara J, Komine H, Maeda S, Yokoi T. Effects of Aerobic Exercise Training on the Stiffness of Central and Peripheral Arteries in Middle-Aged Sedentary Men. Jpn J Physiol. 2005;55(4):235–9. Hayashi et al. did not observe any significant difference in peripheral PWV with medium intensity (75% of heart rate reserve) walking and jogging exercises of 45 minutes for 2-3 days per week in middle aged sedentary individuals.2121.Koichiro Hayashi K, Sugawara J, Komine H, Maeda S, Yokoi T. Effects of Aerobic Exercise Training on the Stiffness of Central and Peripheral Arteries in Middle-Aged Sedentary Men. Jpn J Physiol. 2005;55(4):235–9. According to these results investigators suggested that it would be difficult to bring about a significant change of peripheral arterial stiffness with aerobic exercise. Notwithstanding Schmidt-Trucksaess et al. indicated that femoral arterial diameter and compliance in endurance trained males such as cyclists, short-distance runners and triathletes who had trained for 30 hours per week in average for at least 14 years were significantly larger than those in age-matched sedentary counterparts.2727.Schmidt-Trucksaess A, Schmid A, Brunner C, Scherer N, Zaech G, Keul J, et al. Arterial proper- ties of the carotid and femoral artery in endurance- trained and paraplegic subjects. J Appl Physiol. 2000;89(5):1956-63. In a recent meta-analysis on the effect of combined aerobic and resistance training versus regular aerobic training on peripheral arterial stiffness the benefit of aerobic exercise was proven.2828.Montero D, Vinet A, Roberts CK. Effect of combined aerobic and resistance training versus aerobic training on arterial stiffness. Int J Cardiol. 2015;178:69-76. Montero et al. examined the carotid femoral PWV in a meta-analysis about the effect of aerobic exercise which we took as peripheral arterial stiffness in our study.2828.Montero D, Vinet A, Roberts CK. Effect of combined aerobic and resistance training versus aerobic training on arterial stiffness. Int J Cardiol. 2015;178:69-76. The subjects of the studies included in the meta-analysis were generally sedentary healthy or chronically ill who performed medium intensity walking and cycling exercises of 30-40 minutes per day 2-3 days per week for 8-26 weeks. Aerobic exercised reduced their pwv 0.52 m/sec more than the control counterparts. The same meta-analysis did not show any additional benefit of combined endurance and aerobic training versus only aerobic exercise. In a study with marathon runners who trained 15 hours per week for 12 years in average (6.89 m/sec) carotid femoral PWV was interestingly found to be higher compared to their sedentary counterparts (6.33 m/sec).1515.Vlachopoulos C, Kardara D, Anastasakis A, Baou K, Terentes-Printzios D, Tousoulis D, et al. Arterial Stiffness and Wave Reflections in Marathon Runners. Am J Hypertens. 2010;23(9):974-9. Investigators stated that aerobic exercise had a U-shaped effect on arterial stiffness and might be harmful after a certain level although exercise was generally beneficial. In our study peripheral arterial stiffness measured as PWV was found to be significantly lower in soccer (6.73 m / sec) and basketball players (5.76 m / sn) compared to their sedentary controls (7.89 m / sec).1515.Vlachopoulos C, Kardara D, Anastasakis A, Baou K, Terentes-Printzios D, Tousoulis D, et al. Arterial Stiffness and Wave Reflections in Marathon Runners. Am J Hypertens. 2010;23(9):974-9. These results indicate that ball sports might benefit peripheral arterial stiffness.

How regular aerobic exercise affects arterial compliance is not known for certain. It would not be accurate to single out a mechanism of action. Most probably the two responsible mechanisms of action are sympathetic tonus reduction through aerobic exercise and increased endothelium-dependent vasodilation associated with improved endothelial function.2929.Hautala AJ, Maekikallio TH, Kiviniemi A, Laukkanen RT, Nissilae S, Huikuri HV, et al.

Endurance exercise reduces the plasma concentration of ET-1 which is a potent vasoconstrictor peptide and increases the concentration of nitric oxide which is an endothelium derived relaxation factor.3434.Maeda S, Miyauchi T, Kakiyama T, Sugawara J, Iemitsu M, Irukayama-Tomobe Y, et al.

Thus the smooth muscles of the veins relax. Nitric oxide is reported to play an important role in buffering the arterial system by increased arterial stiffness caused by inhibition of nitric oxide synthase.4040.Wilkinson IB, Qasem A, McEniery CM, Webb DJ, Avolio AP, Cockcroft JR. Nitric oxide regulates local arterial distensibility in vivo. Circulation. 2002;105(2):213-7.
