股直肌肌內效貼紮對女性大專生下肢疲勞後進行急停跳動作的影響

Effect of rectus femoris kinesio taping on female college students during a stop-jump task post-fatigue

緒論：在目前的大學中，越來越多人從事運動的同時，運動傷害的人數也逐漸增加，而多數的運動傷害往往都發生在疲勞發生後，其中女性更因為天生生理上與後天訓練及肌肉力量上，相較於男性都有較高的傷害風險。因此，本研究目的為探討股直肌肌內效貼紮後介入快速疲勞對急停跳動作的著地期運動學、動力學、逆動力學及能量學等生物力學參數變化情形，藉此給予回饋，並瞭解肌內效貼紮是否能有效降低傷害風險。方法：招募11位女性健康大專生為研究對象，由同一位物理治療師進行股直肌肌內效貼紮，使用2塊Kistler測力板及10台Vicon紅外線攝影機同步擷取急停跳動作，並主要分析1分半鐘下蹲跳疲勞介入急停跳動作有無貼紮及疲勞前後著地緩衝期的差異，所得資料使用SPSS 20.0以重複量數二因子變異數分析（α＝.05）。結果：研究結果發現在女性大專生上發現，在無貼紮狀況下，疲勞後增加了地面向後及垂直反作用力、著地後50ms內向後衝量及髖關節吸收度；貼紮介入後降低了垂直分力峰值與延緩向後分力峰值時間、向後與垂直分力峰值負荷率與降低髖關節伸展力矩，更降低了疲勞後的向後分力峰值與著地後50ms內向後衝量。結論：肌內效貼紮對於女性大專生在疲勞前後都能達到降低緩衝期膝關節負荷，但對運動表現的立即效果卻無所增加，建議若需要進行較為激烈的反覆跳躍運動可以進行預防性的股直肌肌內效貼紮。

Introduction: A growing interest in sports has resulted in an increased number of sports participants and a gradual increase in sports-related injuries. Most sports-related injuries occur after the onset of fatigue. Women are at higher injury risk than men due to differences in physiology, training approach, and muscle strength. This study investigated the effect of Kinesio taping, followed by instant fatigue intervention, on a stop-jump task in women. Method: Eleven healthy female college students with an exercise frequency at least three times per week were recruited as participants in this study. Two Kistler force plates and ten Vicon infrared cameras were synchronized to capture the stop-jump task. Differences in the landing period during the stop-jump task before and after 90-s squat jump muscle fatigue were analyzed. Statistical analysis was performed separately through repeated-measures two-way analysis of variance using SPSS 20.0 (α = .05). Result: In healthy college students without taping, posterior and vertical ground reaction force (GRF), 50-ms posterior momentum, plantar flexion torque, and joint contribution at touch-down increased after fatigue. We observed lower peak vertical GRF, delayed time of peak posterior GRF, lowered posterior and vertical peak loading rates, reduced hip extension torque, and total hip net negative work after taping. Furthermore, healthy college students with taping had lower peak posterior GRF and 50-ms posterior momentum after fatigue. Conclusion: These results indicated that Kinesio taping reduced the landing load and the pressure on the knee, regardless of the fatigue state, but had no acute effect on enhancing performance. We recommend preventive Kinesio taping for intense exercises that involve repeated jumping.
