震動訓練對排球選手肩關節肌力及柔軟度之影響

Abstract

Purpose: The aim of this study was to compare the effect of vibration and static stretching on shoulder strength and flexibility of volleyball athletes.Methods: Fifteen female volleyball athletes were randomly divided into 2 groups: 8 athletes who received vibration training were allocated to the vibration-stretching group and 7 athletes who did not receive vibration training comprised the static-stretching group. During a 6-week training period, pre- and post-tests were conducted using a Biodex system to evaluate the shoulder flexibility and the maximal isokinetic torque of the biceps and the anterior deltoid muscle.Results: After 4 weeks of training, the maximal isokinetic torque of the biceps muscle significantly increased with vibration. The static-stretching group showed better improvement in the maximal isokinetic torque of the anterior deltoid muscle. Flexibility performance was significantly increased in both vibration-and static-stretching groups. The vibration-stretching group could increase flexibility more quickly, and the effect accumulated with time, although there was no significant difference between the 2 groups.Conclusions: In volleyball athletes, vibration stretching could simultaneously increase shoulder strength and flexibility, which improved more quickly in vibration-stretching group than in the static-stretching group. The peak effect was observed within 4 weeks of training.
