The comparative study of three stretching methods of static, ballistic and PNF in hamstring length changes in female and male students of Semnan University of Medical Sciences.
The aim of this study is the comparison between three stretching methods on hamstring length. 80 volunteers with short hamstring muscles in 90-90 test will divide randomly in 4 groups of static stretch, ballistic stretch, PNF and control group .10 male and 10 female will be placed in each groups. The hamstring interventional groups will be stretched 3 times a week during 4 weeks. Each stretching technique will last 30 second each session and 360 second totally. The participants in static stretching group will take a 30 second stretching each session and participants in ballistic stretching group will take three stretching techniques that last 2 seconds with 8 seconds rest between each trial. The participants in PNF group will be stretched 10 seconds during 2 trials with 10 seconds rest between them. The control group will receive no stretching techniques. The range of motion will be measured before, immediately after and 4 weeks after intervention.
