本研究主要目的在模擬一般倉儲作業時，不同的施力高度與水平距離對於靜態水平拉力的影響。本研究共徵募12位男性受試者，量測其在四種施力高度(40, 80, 120, 160 cm) 與四種水平距離(10, 20, 30, 40 cm)之作業變項組合下的靜態拉力值。研究結果發現，施力高度對於水平拉力值的影響遠高於水平距離，拉力值隨水平距離增加呈現線性微幅降低，整體降幅約為20%，但施力高度從40cm至 120cm時，拉力值降幅約為30%，至160cm 時卻高達58%，顯示較高的施力位置不利於拉力的發揮。綜合而言，過去文獻中不同作業變項對於靜態抬舉肌力(施力向上)的影響，明顯與水平拉力有所不同，此結果對於現場作業設計具有實務參考價值。

The objective of the study was to examine the effects of the exertion heights and horizontal distances on static pulling forces for simulating warehouse tasks. Twelve male participants were recruited and required to determine their maximal static pulling forces under 16 task combinations with 4 height levels (40, 80, 120, 140 cm) and 4 horiztal distances (10, 20, 30, 40 cm). Results showed that the influences of the exertion heights in pulling forces were more sighificant than that of horizontal distances. The pulling forces slightly decreased with increased horizontal distances and with a total decrease of 20%. The pulling forces decreased around 30% while exerting height from 40 cm changed to 120 cm whereased around 58% from 40 cm changed to 160 cm. This implied that the higher levels caused the disadvantage in exerting pull forces. Consequently, the differdnce did exist in the influences of horizontal distances as well as exertion heights between the pulling forces and lifting forces that has been well-investigated. The result would be considered as a reference to the design for warehouse tasks.
