股直肌肌內效貼紮對大專女性運動員下肢疲勞後進行急停跳動作之影響

Abstract

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之緩衝期運動學、動力學、逆動力學及能量學等生物力學參數變化情形。大專女性甲組運動員及健康大專生各11位為研究對象，使用2塊Kistler 測力板及10台Vicon紅外線攝影機，以Vicon Nexus 1.85軟體同步擷取急停跳動作，並將所得數據經由Visual3D V5軟體濾波與運算，並主要分析著地緩衝期，所得資料使用SPSS 20.0以兩組 (運動員與非運動員分開探討) 重複量數二因子變異數分析 (a=.05)。研究結果發現在大專甲組運動員在無貼紮狀況下，疲勞後同時也增加了垂直分力峰值負荷率及膝關節向後之剪力；貼紮介入後延緩了髖關節屈曲角度峰值時間與前後分力峰值時間、降低垂直分力峰值及50毫秒內與緩衝期垂直衝量，同時也延緩了疲勞後垂直分力峰值的發生時間；在健康大專生上發現，在無貼紮狀況下，疲勞後增加了地面前後及垂直反作用力、50毫秒內前後衝量及髖關節吸收度；貼紮後降低了垂直分力峰值與延緩前後分力峰值時間、前後與垂直分力峰值負荷率與降低髖關節伸展力矩，更降低了疲勞後的前後分力峰值與50毫秒內前後衝量與跳躍高度的下降幅度。由上述結果結論，肌內效貼紮對於大專甲組運動員或健康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。The purpose of this research was to study the effect of Kinesio taping, followed by instant fatigue intervention, on stop-jump task. Eleven Division I collegiate female athletes with 4 years of specialized training, and 11 healthy college students with exercise frequency of over 3 times per week, were recruited as participants. Two Kistler force plates and ten Vicon infrared cameras were synchronized with Vicon Nexus 1.85 software to capture the stop-jump task. Visual3D V5 software was used for filtering and calculating. Statistics of each group was performed separately with repeated-measure two-way ANOVA using SPSS 20.0 (a=.05). We found in the athlete group with, at touch down, when without taping, peak vertical loading rate and knee backward shear force were increased. After taping, we found delayed time of peak hip flexion angle and peak anterior-posterior force, lower peak vertical force, lower vertical momentum within 50 ms and during landing phase, along with delayed time of peak vertical force after fatigue. In the healthy college students, at touch-down, without taping, anterior-posterior and vertical GRF, 50ms ant-pos momentum, plantar-flexion torque and joint contribution were found increased after fatigue. Lower peak vertical GRF, delayed time of peak ant-pos GRF, lowered ant-pos and vertical peak loading rate, decreased hip extension torque and total hip net negative work were found after taping. Furthermore, peak ant-pos GRF, 50 ms ant-pos momentum and jumping height decrease were found lower after fatigue. It concluded from the results, that Kinesio taping can decrease the load in landing and the pressure on knee whether fatigue or not, in both Division I collegiate athletes and healthy college students, but has no acute effect on enhancing performance. We recommend that preventive Kinesio taping be applied on intense exercises with repeated jumping.
