膝關節是人類身體內最大的關節,支撐著人體的重量、膝蓋的屈曲和伸直。前十字韌帶(Anterior Cruciate Ligament, ACL)損傷約有7成發生於運動中(跳躍、急停、變換方向等各種動作),其中有7成是屬於非接觸型損傷。運動員一旦ACL受到損傷後要再回到競技場上,都需要6個月以上的治療與復健。現在,世界各國將焦點集中於如何能有效的預防與降低ACL損傷。不管預防ACL損傷運動模式介入訓練的長或短,都能達到一定的預防效果;然而,介入期間過長會影響到正規訓練,選手也會感到乏味,短時間有效率的方案,較為大多數運動團隊接受與實施。未來研究方向,可以將預防ACL損傷運動模式推廣至國高中、大學代表隊或社會隊,探討是否能有效降低ACL的損傷。
The knee joint is the largest joint in the human body, sustaining the body weight and allowing legs to bend and straighten. An estimation of 70% Anterior Cruciate Ligament (ACL) injuries occurred during jumping, stopping suddenly, and changing directions and 70% of those injuries were through the non-contact mechanism. Athletes with ACL injuries usually need more than 6 months of treatment and rehabilitation before returning to the sport. Nowadays, countries all over the world strive to prevent and reduce ACL injuries. The prevention program for ACL injuries may reach the effects to some extents regardless the length of intervention. However, if the intervention program takes far too long, athletes may feel bored. A short and efficient program is often preferred and executed by most sport teams. Future research directions could promote the effective prevention program among high schools, universities, or club teams and investigate the efficiency in reducing ACL injuries.
