Abstract

|
|
Purpose：The purpose of this study was to find out which method was efficient to enhance the flexibility of lower back between PNF(proprioceptive neuromuscular facilitation) and hamstring stretching.
Method：subject were 20 young people between the ages 20 and 25. subjects were randomly assigned to one of 2groups; PNF(n=10), static(n=10). respective group received the same stretching does of 3days per week for 4weeks. Trunk flexion forward a measuring instrument and tapeline were performed to measurement the flexibility of lower back at different times(before starting the exercise, 4weeks after starting).
Results：The results of the study were as follows: The lower back flexibility was increased significantly in PNF groups. PNF, static groups showed meaningful defference in trunk flexion forward. The finding indicate that PNF may be preferred technique for improving flexibility and that flexibility training results in on increased consistency of flexibility scores
