Background : The purpose of this study was to investigate the effects of stati cs stretching and fascia stretching on hip joint range of motion, muscle strength, and pelvic alignment. This study was conducted on 31 subjects without back pain. Methods : Subjects were divided into two groups; static stretching(group Ⅰ, n =11), fascia stretching(group Ⅱ, n=13). Both groups executed the exercise thre e times a week for 4 weeks. The ranges of hip motion were assessed by gonio meter, the muscle strenth was conducted by Microfet2, and the pelvic alignment was assessed by Posturemeter before and after in both groups. The data was analyzed by the paired t-test to compare differences before and after on each group and the independent t-test to compare between the two gro ups. Results : In groupⅠ, showed significant increases in bilateral flexion, extensio n, and lateral rotation, while in groupⅡ, left abduciton and right lateral rotation i ncreased significantly. In groupⅠ, the difference of stretch of hip muscles was n o significant before and after, however, in groupⅡ, the strength of right lateral r otation significantly increased. There was no statistically difference in range of motion, strength, and pelvic alignment in between groups. Conclusion : According to the results, stretching exercises are effective for en hancing range of motion and pelvic alignment; however, they do not significatly i mprove muscle strength. To increase muscle strength, it is necessary to perform both stretching and strengthening exercises concurrently.
