中文摘要 | 本研究目的為探討不同足部站立位置與啞鈴負荷對蹲舉的膝關節三維動力學的影響,受試者為10名男性舉重專長選手,平均年齡21歲,利用Vicon動作分析系統及Kistler力板,分析在體重和啞鈴負荷狀態下蹲舉動作的膝關節力量和力矩,並使用4種不同足部站立位置(窄站立位置、足外旋窄站立位置、足外旋中站立位置與足外旋寬站立位置)。統計使用二因子重複量數變異數分析,比較不同負荷和站立位置的膝關節動力學差異,若主要效果達到統計的顯著性,則使用LSD進行事後檢定。本研究結果發現在蹲舉運動時不同站立位置會顯著影響膝關節向內力量、壓力和外旋力矩。蹲舉運動膝關節力量主要為向後力量,在足外旋寬站立位置下有較小的向內力量與外旋力矩,但會產生較高的膝關節壓力。另外,使用啞鈴負荷會增加膝關節向後力量、壓力和伸直力矩,顯示啞鈴蹲舉運動為有效的股四頭肌訓練方式,但也須注意到伴隨著提高了膝關節壓力及向後剪力。本研究結論為不同足部站立位置與是否使用啞鈴負荷會顯著影響蹲舉時膝關節的力量和力矩,此結果可以提供使用蹲舉作為肌力訓練或復健治療者進行蹲舉運動之參考。 |
英文摘要 | The purpose of this study was to investigate the effects of stance configuration and dumbbell load on knee kinetics in squat. Ten weight lifting athletes with average age of 21 years old were participated in this study. Vicon motion analysis system and Kistler force plate were used to analyze the three-dimensional knee joint forces and moments in two load conditions, body weight and dumbbell. In addition four stance widths, including narrow stance, narrow stance & toe out, medium stance & toe out and wide stance & toe out were also used in this study. Two-way analysis of variance with repeated measures was used to compare the kinetic differences between different stance configurations and dumbbell loads. If statistical analysis reached significance on the main effect, LSD method was used for further post hoc analysis. The results showed that medial force, compression and external rotation moment in the knee joint were affected by stance configuration. Knee joint force during squat was found to be posterior force. Wide stance & toe out showed a lesser medial force and external rotation moment but a higher compression. Moreover, the use of dumbbell in squat increased the posterior force, compression and extension moment. Dumbbell squat was an effective exercise for quadriceps strengthening but it should be cautious for the higher compression and posterior shear force. This study concluded that knee joint force and moment during squat would be substantially affected by stance configuration and the use of dumbbell. These findings could be served as useful biomechanical guidelines for those, who use squat for muscle strengthening or rehabilitative treatment. |
