Purpose：This study aimed to examine the Influence of muscle strengthening exercise and stretching exercise of trunk extensor muscles on muscular strength and flexibility in adolescent of the twenties.
Methods：Muscle strengthening exercise group(n=10), stretching exercise group(n=10) and strengthening and stretching exercise group(n=10) were measured muscular strength by digital back and leg dynamometer and flexibility by sit and reach test and trunk extension test at pre-intervention and post-intervention in 4weeks.
Results：The flexibility 1, flexibility 2 and muscular strength of muscle strengthening exercise group were significantly increased within the intervention period(p＜.05). The flexibility 2 and muscular strength of stretching exercise group were significantly increased within the intervention period(p＜.05). but flexibility 1 was not significantly different at in 4 weeks(p>.05). The flexibility 1, flexibility 2 and muscular strength of muscle strengthening and stretching exercise group were significantly increased within the intervention period(p＜.05).
Conclusion：We were found that muscle strengthening exercise and stretching exercise of trunk extensor muscles could improve muscular strength and flexibility for adolescent of the twenties.
