RESULTS In LBM and Body fat percentage, there was no significant difference after exercise. In other words, there was significant difference in body fat (p<.001). Physical fitness has some significant difference in muscular strength, muscular endurance, power, balance and flexibility (p<.001; p<.001; p<.05; p<.05; p<.001). But there was no significant difference in VO2max. There was no significant difference in BDNF and Irisin for groups after exercise.
