복합트레이닝이 고등학교 투척 선수의 유연성 및 요부 근력에 미치는 영향

Abstract

The purpose of this study is to provide the fundamental data regarding stable position, injury prevention, and effective training method for the weight thrower with estimate of flexibility (trunk-hip forward flexion) and lumbar strength (30°/sec, 120°/sec) to identify the effects of combined training on flexibility and lumbar strength of high school weight thrower. The target of this study was 10 weight throwers, randomly assigned by 5 for exercise group and 5 for control group, in K sport high school, located at G metropolitan city; for 8 weeks, the program was conducted 3 times per week. And the method and procedure of study are as follows: 1. Regarding the change of flexibility, there was found significant difference among the statics of group (<.05), period(<.03), group*period(<.01). 2. Regarding the change of peak torque in 30°/sec isokinetic lumbar strength, there was found significant difference among the statics of extensor muscle group (<.05), period(<.02), flexor muscle group(<.01), and period(<.01); there was found insignificant difference in the statics of group*period for both of extensor and flexor muscle. Also, there was found insignificant difference in total work among both of extensor and flexor muscle. 3. Regarding the change of peak torque in 120°/sec isokinetic lumbar muscular endurance, there was found medial difference in the extensor muscle but significant difference in the flexor muscle among group(<.04) and period(<.04), except group*period. Regarding the total work, there was found medial difference in both of extensor and flexor muscle. As shown in the result, it was found that application of the combined training (weight training+lumbar Pilates program) had positive effects on the flexibility (trunk-hip forward flexion) and lumbar strength (peak torque and total work of extensor and flexor muscle) and the positive effects would help function of abdomen in correction of posture and movement for thrower in future. Also, since the target was elite athletes rather than general public, the effects would be more exactly assessed and the balance would be increased and the muscular strength in other area would be maximized if the strength and movement of the exercising program is more segmentalized and conducted in long-term.
