Physiological adaptation of anthropometric and cardiovascular parameters on physical activity of elite athletes

Introduction. Specific morphological and functional characteristics of athletes have a significant role in determining athletes’ sports results and can be also used to assess the athlete’s individual potential. Objective. The aim of the study was to compare anthropometric characteristics and cardiovascular parameters in trained subjects to those of untrained subjects. Methods. A total number of 25 trained (17.30±0.83 years) and 21 (18.52±1.52 years) untrained male subjects participated in this study. Body weight and height were measured and these values were used to compute body mass index (BMI). The bioelectrical impedance analysis (BIA) method was used to estimate body fat percentage (%BF). Cardiovascular parameters were monitored in rest (rest heart rate, systolic and diastolic blood pressure) during ergospirometric testing (maximal oxygen consumption, maximal heart rate) and in recovery (heart rate in the first and third minute of recovery). Results. Body mass, height and BMI (p<0.01) were significantly higher, although BF% was lower in trained group when compared to untrained, but the difference was not statistically significant. Heart rate in rest and recovery were significantly lower (p<0.05) in trained group when compared to untrained, although maximal oxygen consumption and maximal heart rate were significantly higher in trained group (p<0.01, p<0.05, respectevely). Conclusion. Our results show that in trained subjects, water polo players, regular intense physical activity lead to adaptive changes of anthropometric parameters and adaptive changes on the cardiovascular system.
