| Abstract |
The aim of this study was to analyse the possible influences of body composition above tests of speed, acceleration and changes of direction in university students, as well as differences between genders. One hundred fifty-five university students (men= 121; women= 34; age= 20.56 +/- 1.23 years) participated in the study. Body composition and performance were evaluated in tests of 10 meters, 50 meters and 5x10 meters. The differences between gender and the correlations between the parameters of body composition and the times in the different tests were analysed. The results show better times in the speed tests in men, as well as a greater waist circumference, muscle percentage, muscle weight, body mass index (BMI) and waist hip ratio (WHI) (p <0.05). Positive correlations were observed between the times of the tests evaluated in the total of subjects and in men (p <0.05), but not in women. In the male group, the total weight, fat weight and fat percentage were directly related to time in all test. Contrarily, muscle weight and muscle percentage were inversely related (p <0.05). In the female gender, there was a direct correlation in the 50-meter test with fat weight, fat percentage, sum of folds and hip perimeter (p <0.05). In conclusion, a greater muscle mass and muscle percentage results in a better performance in the tests of 10 meters, 50 meters and 5x10 meters. However, a higher fat percentage and fat weight negatively influences the performance of the mentioned trials. Body composition could be an important control parameter for performance in speed tests and changes of direction. |
