Effects of Weight Training on Body Composition of University Badminton Class Students

並列摘要


The purpose of this study was to investigate the effect of weight training on body composition in the university badminton class students. Sixty-five students with mean age of 20.14 ± 1.46 yrs; height 169.8 ± 7.41 cm; body mass 63.31 ± 10.73 kg (44 males, 21 females) attended weight training courses, once a week, 30 minutes per class for 12 consecutive weeks. They were tested before and after the training in body composition by the body composition analyzer (Inbody 3.0). The body composition tests were including: body mass, muscle mass, body fat mass, percent body fat, waist-hip ratio (WHR), arm strength, leg strength, trunk strength. The data was processed by SPSS for windows 12.0 software system and the t-test was used to analyze the comparison of before and after training in all tested subjects. The significant level was set at α = .05. The results were as follows : (1) After the 12-week continuous training, body composition items including body mass, muscle mass, body fat mass, body fat percentage and waist-hip ratio of overall students, all reached level of significance (p < .05), except muscle mass (p > .05). (2) The body composition including average weight, body fat mass, body fat percentage, and waist-hip ratio of male and female students were decreased. The muscle mass of male was decreased while female was increased. (3) The arm strength, trunk strength, and leg strength of all students were increased. The increase of trunk strength was most significant. The arm strength of female was below the average value. This shows that the arm strength of female university students was insufficient. The leg strength of male and female students was increased significantly after the training. (4) The arm strength, trunk strength, and leg strength of male students were increased and reached the level of significance (p < .05). The muscular strength of different parts of female students was increased. However, only the leg strength reached the level of significance (p < .05). We concluded that the 12 weeks weight training courses actually improve the body composition of students.
