股関節外転運動後の大腿筋膜張筋と腸脛靭帯の硬度変化と振動刺激がそれに与える影響

抄録

The aim of this study was to evaluate the transition of the tensor fasciae latae (TFL) and the iliotibial band (ITB) hardness after repetitive hip abduction exercise (RE) and the effect of vibration stimulation immediately after RE. Nine healthy man performed the RE (20 reps×5 sets) and the TFL and the ITB hardness were measured before and after RE. Participants were performed RE by 2 conditions(i.e. with and without vibration stimulation after RE). The results showed that with no vibration condition, hardness of the TFL significantly increased immediately, 15 min, 30 min, and 24 hours and the ITB significantly increased immediately, and 24 hours after RE compared with before RE, respectively. With vibration condition, vibration after RE, both of the TFL and the ITB hardness significantly increased only immediately after compared with before RE. On the other hand, TFL and ITB hardness significantly decreased 15 min, 30 min, and 24 hours compared with immediately after RE. In addition, with vibration condition, TFL and ITB hardness significantly decreased 15 min, 30 min, 24 hours compared with no vibration condition, respectively. This study indicated that the ITB hardness might be increased with excessive activity of TFL, and the vibration stimulation immediately after exercise is effective for decreasing the hardness.
