| Abstract | ||||
| The aim of the present study is to identify the effect of 8 weeks plyometric training on step kinematics and lower limb stiffness during maximum velocity phase in young sprinters, the research subjects was divided into 2 groups plyometric group and control group the training program was applied for 8 weeks with pre and post testing .For plyometric group, there was a significant differences between pre and post test for step length ,frequency and contact time.Also,sprint times and both vertical and leg stiffness improved significantly. However, when comparing PG and CG in post test there was no significant differences between both groups in the post test except for ΔL for PG and that may be due to the short period of the training program. So the researcher suggests that plyometric training is an effective method to improve sprint kinematics and lower limb stiffness considering that neural adaptation may take long time to occur | ||||
