中文摘要 | 本研究的主要目的是為了解由雙手伏地挺身到單手伏地挺身過程中肘關節受力的變化。實驗時所使用的儀器包括人體動態分析系統與一塊測力板,用來量測並計算由雙手伏地挺身到單手伏地挺身過程中肘關節受力的情形。結果發現在單手伏地挺身時比起雙手伏地挺身有較大的旋後/旋前(pronation/supination) 角度變化 (P<0.05) 以及5倍後側剪力 (posterial shear force) 與2.5倍的屈曲力矩 (flexion moment),而這樣大的手肘後側剪力與屈曲力矩改變,不僅僅是由支撐力量的增加,而且是由關節在運動過程中受到限制與肌肉力量的協調因素所致。因此對於手肘周圍韌帶受傷的人在從事由雙手伏地挺身到單手伏地挺身時應該特別注意,避免後側剪力與屈曲力矩所造成的傷害。 |
英文摘要 | The purpose of this study was to compare the differences of the elbow joint load between two-handed and one-handed pushup exercises. Elbow joint loading was evaluated during two-handed and one-handed pushup exercises using a motion analysis system and a force plate. Results show that in one-handed pushup, large pronation/supination angles were found (p<0.05) and posterial shear force and flexion moment were increased 5 times and 2.5 times, respectively, compared to two-handed pushup. It was noted that greater posterior shear forces and flexion moments of the elbow are encountered not only from loading increasing but also from the muscle coordination for the constraint of joint. Therefore, people with elbow ligament injury are suggested to pay more attention to heavy posterial shear force and flexion moment to avoid injury from two-handed pushup to one-handed pushup. |
