Effects of Three Weeks Plyometrics on Sprint Velocity

In Plyometrics the muscles store energy during the landing (stretching phase) which is released in the immediate rebound. The stretching during the lowering stimulates the nervous tissue within the muscles. This result in a greater number of muscle fibers called into action and stimulates closely the situations like sprinting. The study analyzed the effect of plyometrics on sprint velocity in male sprinters of 20-25 years with minimum of one year athletic background. Out of 30 male subjects aged between 20-25 years, 15 were selected conveniently for experimental group (GROUP B) and 15 randomly for control group (GROUP A). For both the groups 3 week research was done. The training session was held once a week. On each training day both the control group and experimental group started their warm up exercises for 40 minutes. After the warm up the experimental group were subjected to Plyometrics. The assessment of running time through 60 meter was assessed after every week. On comparing the both groups it was found that both groups show statistically insignificant improvement after week 1 but experimental group show statistically significant improvement after week 2 and week 3 as compared to control group.
