  • Description: 目的：本研究目的為比較兩種下拉器材（機械、彈力繩）與不同自覺負荷（輕、中等、重、接近最大努力）來探討相關肌群進行下拉過程中肌肉活化程度。方法：招募10名健康男性大專生，黏貼肌電訊號後完成指定器材下拉，分別以四個負荷區間執行指定下拉次數，使用自覺量表(Borg CR10)作為評估負荷的工具，再以荷重元及肌電訊號的數據進行分析，以動作間最大值作為肌電圖標準化的基準，統計方法以二因子變異數分析進行統計考驗不同器材與負荷下肌肉活化程度的比較(α = .05)，當交互作用達顯著時，進行單純主要效果考驗，事後比較處理為Bonferroni法。結果：一、荷重元強度與自覺量表強度與自覺量表成正遞增；二、在相同自覺負荷下，使用機台之荷重元強度顯著大於彈力繩；三、向心階段，使用不同器材與負荷中，肌肉活化程度沒有差異；四、離心階段，使用下拉機台時，闊背肌與後三角肌的活化大於使用彈力繩。結論：自覺量表可以作為評估此運動強度的工具，在相同水平的自覺負荷下，不同器材表現出類似的肌肉活化程度，因此，本研究認為彈力繩可以成為下拉訓練的替代工具。.
    Purpose: The purpose of this study was to compare muscle activity of upper back muscles between two pull down exercises by using lat-pull down（LPD）machine and elastic resistance band（ERB）. Methods: There were 10 healthy males participated in the study. Using the Borg scale, Load cell and EMG in this study. EMG activities were recorded from 5 muscles at the upper body during different pull-down exercise, using ERB and LPD machines. These recordings were normalized to EMG signals during maximal voluntary contraction. Five muscles have been analyzed during two pull down exercises were latissimus dorsi (LD), pectoralis major (PM), biceps brachii (BB), triceps brachii (TB), and posterior deltoid(PD). The exercises were performed at four levels of perceived loading reported using the Borg scale of perceived exertion: light (Borg ≤2), moderate (Borg >2-<5), heavy (Borg ≥5-<7) and near maximum (Borg ≥7). Two-way ANOVA with repeated measures was conducted for statistical analysis. The significant level was set at α = .05. Post hoc comparisons were performed using the Bonferroni test, if statistical significance was found among the groups. Results: 1. Strong associations were observed between perceived loading and Load cell signals during the pull-down exercises with ERB as well as in LPD machine. 2. In the same level of Borg scale, LPD machine is higher than ERB in Load cell force values. 3. In the concentric phase, EMG values are no significant difference in all muscles. 4. In the eccentric phase, greater normalized EMG values were found for the LD and PD in LPD machine. Conclusion: ERB may be able to increase the muscular strength of the upper back and arm muscles similar to that of the LPD exercise. Therefore, ERB can be considered a feasible alternative training method to LPD exercise, especially when the availability of training equipment is limited.
