초록

This study aimed to find out the effect of isometric muscle contraction by body parts(musculus pectoralis major, deltoid muscle, biceps brachii muscle, triceps brachii muscle, and latissimus dorsi muscle of open-chain(Bench-press) and closed-chain exercise(Sling). The study was conducted with healthy 24 college men, who were divided into three groups(Control, Bench-press, Sling groups) by sampling up to 8 a group randomly. And it was conducted 3times a week for 12 weeks. As for statistical methods, Paired-samples t-test analysis and two-way ANOVA were implemented with SPSS Windows 14.0 program. The significance level was α=.05.
As for the results of this study, First, there was effect in the order of musculus pectoralis major > deltoid muscle > triceps brachii muscle > latissimus dorsi muscle > biceps brachii muscle in isometric muscle contraction by body part before and after exercise with Bench-press exercise, and there was a very significant difference in the statistical significance level(p<.05). Second, there was effect in the order of deltoid muscle > musculus pectoralis major > triceps brachii muscle > latissimus dorsi muscle > biceps brachii muscle in isometric muscle contraction by body part before and after exercise with Sling exercise, and there was a very significant difference in the statistical significance level(p<.05). Third, compared with the control group, there was a big effect between a Bench-press group and a Sling group in isometric muscle contraction by body part before and after exercise according to the types of exercise, and there was a very significant difference in the statistical significance level(p<.001). However, although there was a bigger effect in Sling exercise than Bench-press exercise, there was no significant difference.
After considering the results above, as it appeared that Sling exercise had an effect on the muscular enhancement(Isometric muscle contraction) to the common people, it is hoped that exercise load index for 1-RM estimate of Sling exercise may be helpful to the injury prevention and the improvement of performance of every person and elite athletics who use Sling exercise by being applied to them.
