Abstract

|
|
Purpose：The purpose of this study was to compare the effectiveness of passive stretching, active stretching, and proprioceptive neuromuscular facilitation(PNF) for hamstring flexibility.
Methods：Fifty-two college students volunteered for this study. Subjects were randomly devided into three groups : passive stretching, active stretching, PNF. Range of knee extension was measured with the subjects in the 90-90 straight leg raising at before and 1, 2, 3, 4 weeks after intervention.
Result : In ROM changes 1st week, 3 groups were significant difference(p<.05). In ROM changes 3rd week, PNF group was significant difference(p<.05). ROM changes 1st week were significantly decreased from ROM changes 2nd week and 3rd week in all 3 groups(p<.05).
Conclusions：The results of this study suggest that PNF is more effective method on hamstring flexibility than passive stretching or active stretching.
