The objective of this randomized trial is to investigate the effect of plyometric exercise in static and dynamic balance indices in athletic and non-athletic subjects. In this study 100 subjects ( 50 athlete and 50 non-athlete) who meet the inclusion/exclusion criteria will be recruited and randomly assigned into intervention or control group. The subjects in the intervention group will receive plyometric exercise. The subjects in control group will receive no intervention. Intervention lasts for 6 weeks. Static and dynamic balance indices with eyes opened and closed, falling risk and limited stability of all participants will be measured before intervention, immediatelly after and 1 month after the intervention, and will be compared between groups.
