中文摘要 運動是維持身體健康的一項重要因素,但運動傷害也常常伴隨著運動一起發生。要如何保持運動習慣且避免運動傷害,成為目前的重要課題。
肌肉的力量除了產生動作,另一方面也能維持關節的穩定性,避免受傷。但在肌肉疲勞後(After Fatigue),關節的受力與力距會產生什麼變化?而提升受傷的可能性,為此次研究的主要目的。
本次實驗邀請14位無上肢傷殘病史的年輕男性舉重選手參與實驗計畫,在正常速度條件下進行屬於閉鎖式動力鏈運動的伏地挺身(Pushup)與屬於開放式動力鏈運動的仰臥推舉(Bench Press)運動。我們將分析伏地挺身與仰臥推舉兩種運動在疲勞前(Before Fatigue)與疲勞後(After Fatigue),其關節受力、關節力矩、肘關節屈曲角度、單位運動循環時間、關節最大力矩與肌電訊號的變化。
實驗結果發現伏地挺身運動疲勞後,腕關節外側剪力Peak值增加、橈骨側力矩Peak值增加,肘關節前向剪力Peak值增加、外側剪力Peak值增加、外旋力矩Peak值增加,肩關節外側剪力Peak值增加、軸向壓力Peak值減少、外展力矩Peak值增加。肘關節屈曲角度在Down的部分變小、單位循環的運動時間變長、關節最大力矩降低。
發現在仰臥推舉運動疲勞後,腕關節尺骨側力矩Peak值增加,肘關節外側剪力Peak值增加、軸向壓力Peak值減少、外旋力矩Peak值增加,肩關節軸向壓力Peak值減少、外展力矩Peak值增加。肘關節屈曲在Down的角度與單位循環角度皆變小、單位循環的運動時間變長、關節最大力矩降低。
發現在運動循環次數方面,仰臥推舉在較少的運動循環次數下就會疲勞。最大關節力矩衰退率在肘關節伸展、屈曲,肩關節伸展、外展、內收、後旋及前旋皆為仰臥推舉衰退較多。
整體而言,疲勞後因為肌力衰退造成關節搖晃不穩定,而使得關節剪力增加,易提高運動受傷機會。
英文摘要 Exercise and Strengthening of the Upper Extremity is becoming popular. How to avoid injuries during training process is an important issue. The purpose of this study was to investigate the effect of fatigue on joint loading during kinetic chain exercise of the upper extremity.
14 healthy male weight lifter with no trauma history of upper extremity volunteered for this study. They were asked to complete open kinetic chain(Bench press) and closed kinetic chain(Pushup). The Expert Vision Motion Analysis System with eight CCD cameras, and a Kistler force plate was used to measure the relative joint position and ground reaction force. Also surface EMG was used to measure muscle activity. The KIN-COM was used to measure maximum joint moment.
After fatigue of exercise, subjects had decrease elbow range of motion, while the cycle time also increased .Furthermore, it’s necessary to avoid exercising while the upper extremity is fatigue, because the joint shear force is increased after fatigue. In conclusion, bench press is a more efficient exercise to strengthen the upper extremity.
