摘要

推力作業是一種常見於工作現場的人工物料搬運作業型態。要能夠解決推力活動所造成的過度施力與肌肉骨骼傷害，最重要的是建立推力值的資料庫來做為工作場所設計與改善的參考標準。本研究主要目的將量測並探討我國勞工在不同施力高度下男女性勞工的推力值與腳部空間需求，以做為工作場所設計與改善時的重要參考。本研究量測並分析我國勞工在不同施力高度下男女性勞工的推力值與腳部空間需求（步伐距離與後腳距離）。實驗設計為三因子（性別、施力高度、施力手別）重複2次量測的因子實驗。研究結果亦發現，三個因子對推力值和步伐距離的影響都有顯著差異，但只有性別和施力高度對後腳距離的影響有顯著差異。這樣的研究結果可以做為推力作業的工作現場改善或設計的重要參考依據。最後，本研究亦討論研究結果與國內學者較早研究的一致性。

Push activities are very prevalent in various industrial tasks. To avoid the injuries or muscular skeletal disorders by push activities with overexertion in industries and to redesign the tasks, the knowledge of the capabilities of push strengths are important reference. The purpose of this study is to measure and investigate the pushing exertion values and the required foot space under different exertion heights for labors in Taiwan. A three-factor factorial experimental design with two repetitions was conducted in this study. The three factors included gender (male, female), exertion height (40 cm, 80 cm, 120 cm, 160 cm), and hand posture (right hand, left hand, both hands). The results showed that the effects of three factors were significant on pushing exertion values and on step length, while gender and exertion height effect were significant on rear foot distance. These results could be important references for improvement and redesign of the push activities in industries. The consistency between the previous studies and this study was also discussed.
