The purpose of this study was to investigate the effect of combined exercise training during
12weeks on physical fitness, body composition and bone mineral density in university students.
Nineteen male university students who were enrolled of 1st grade at department of physical
education in Korea National University of Education were participated in this experiment. Subjects
were performed combined exercise training - running, physical training using plyometrics and
resistance training - of 5days per week, 70min per 1 time, during 12weeks. The measurement items were health related fitness(muscle strength, muscular endurance, cardiovascular endurance, flexibility), motor skill fitness(power, balance), body composition(% body fat, muscle mass) and bone mineral density(T-score). On the basis of the results analyzed in this study and consideration of many pre studies related it, the result were as follows. First, data analysis of 12 week combined exercise training on health related fitness, post level was revealed more significant increase than pre level at muscle strength(p<.05), muscular endurance(p<.05), cardiovascular endurance(p<.001) and flexibility(p<.05). Second, data analysis of 12 week combined exercise training on motor skill fitness, It was not revealed significant differences between the pre and the post level of the power and balance). Third, data analysis of 12 week combined exercise training on body composition, post level revealed more significant improvement than pre level at muscle mass(p<.05), but It was not revealed significant differences between the pre and the post level of the % body fat. Fourth, data analysis of 12 week
combined exercise training on bone mineral density, post level revealed more significant improvement than pre level at T-score(p<.05). In conclusion, It was revealed that 12 week combined exercise training increased physical fitness, and improved body composition and bone mineral density. I hope that more studies will be followed on physical fitness, body composition and bone mineral density on various exercise types, exercise intensity, time and frequency in university students in the future.
