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.
