【摘要】：背景:相较于其他护具,贴扎最大的不同是可以依照每个人不同关节形状及需求进行不同的改变,可以说是更有效、更方便的量身订作的护具。目的:比较不同膝关节贴扎类型对足球运动员急停动作稳定性的影响,为运动员及一般健身者选择合适的贴扎方式以预防膝伤害提供重要参考。方法:运用运动学、动力学及肌电同步摄取12名男性足球运动员分别在膝关节传统贴扎、肌内效贴扎和无贴扎情况下的急停动作生物力学参数,再以SPSS 17.0软件对相关数据进行处理分析。结果与结论:(1)水平分力峰值、压力中心前后位移量及平均水平负荷率上,传统和肌内效贴扎组显著小于无贴扎组;(2)膝关节角度变化量无贴扎组最小,而爆发力峰值出现时刻膝角及爆发力出现时膝角变化量上,传统及肌内效贴扎组显著大于无贴扎组;(3)股直肌与腓肠肌的平均肌电振幅量是传统与肌内效贴扎显著小于无贴扎组;(4)结果说明,传统与肌内效于膝关节贴扎能显著提升急停动作下肢支撑功能及限制前十字韧带的向前移动量,这对于增加稳定性并保护膝关节免于伤害有益。
[Abstract]:Background: the biggest difference in attachment is that it can be changed according to the shape and needs of different joints. It can be said to be more effective and convenient for tailoring. Objective: to compare the effects of different knee joint attachment types on the stability of the action of soccer players in order to provide important reference for athletes and ordinary fitness people to choose appropriate sticking methods to prevent knee injury. Methods: the biomechanical parameters of 12 male footballers were taken up by kinematics, dynamics and electromyography under the condition of knee joint sticking, intramuscular fixation and non-sticking respectively. Then SPSS 17.0 software is used to process and analyze the related data. Results and conclusion: the peak value of horizontal force, the anterior and posterior displacement of the pressure center and the average horizontal load rate were significantly lower in the traditional and intramuscular effect group than in the non-taped group (P < 0.05). However, when the peak value of explosive force appears, the angle of the knee and the change of the angle of the knee when the explosive force appears, The results showed that the mean myoelectric amplitude of the rectus femoris and gastrocnemius muscle was significantly lower in the traditional and intramuscular effect group than that in the non-taped group (P < 0.05), and the results showed that the mean EMG amplitude of the rectus femoris and gastrocnemius muscles was significantly lower than that of the non-taped group. Traditional and intramuscular fixation of knee joint can significantly improve the lower limb support function and limit the anterior cruciate ligament forward movement, which is beneficial to increase stability and protect knee joint from injury.
