The Effect of PNF stretching in the hamstring muscles on the young speed sprinters

Abstract

Introduction. The aim of this study is the effect of PNF stretching in the hamstring muscles on the speed sprinter young.
Material and Method. Sixteen healthy young male volunteers were tested between the ages of 14-19, training (TRN, n=8) and control (CTL, n=8). Two separate speed testing days were scheduled 5 days apart. All 16 subjects were timed individually during two, 20-yard dash sprints on day 1 and on day 5. A confidence interval of (P≤05) was established a prior for the independent Student t-test in order to determine significant statistical difference.
Results and conclusion. Results showed that experimental group improved speed after PNF stretching. PNF stretching training program may improve the speed and can be used with other training programs.
