운동생리학 : 서킷 웨이트 트레이닝이 등속성근력과 신체조성에 미치는 영향 = The Effect of Circuit Weight Training on Isokinetic Muscle Strength and Body Composition

다국어 초록 (Multilingual Abstract)

The purpose of this study was to investigate the effect of Circit Weight Training on Isokinetic muscle strengh and body composition in college female student.
The subjects who engaged in this experiment exercised at 40% of 1-RM, 12 repetitions, followed by 15 sec as the subject moved to the each break training program which was consist of the Circuit of 10 stations performed on 3 a day, circuits 3 days a week during 8 weeks.
The assessment of isokinetic factor was in concentric flexors and extensors of right and left knee joint. Tests were performed on the Cybex 770 isokinetic dynamometor and Body Composition were estimated the two parts of Triceps and Subscapular by using skinfold caliper, calculated the average and followed by Keys and Brozˇek way.
Statistical analysis were performed using analysis of variance paired t-test, accepting level for all significant was above α =.05 and α=.01.
Following is as a result of 8 weeks circuit weight training.
1. At the 60°/sec the right and left knee Isokinetic concentric flexors and extensors peak torque increased significantly(p<.01) At the 180°/sec the right knee concentric flexors and extensors peak torque increased significantly(p<.01)
2. As a result of 8 weeks Circuit Weight Training, at the 60°/sec, the right and left Isokenetic knee concentric flexors and extensors average power increased significantly(p<.05, p<.01) and at the 180°/sec the right extensors didn`t show any statistical significant.
3. As a result of 8 weeks Circuit Weight Training at the 60°/sec, the right and left Isokinetic knee concentric flexors and extensors total work increased significantly(p<.05, p<.01) but at the 180°/sec right concentric flexors didn`t show any statistical significant.
4. As a result of 8 weeks, the body composition changed significantly(p<.01) These results suggest that 8 weeks Circuit Weight Training increases the peak torque, average power, total work significantly and decreases the %body fat significantly.
