碩士 === 南台科技大學 === 工業管理研究所 === 100 === This study used psychophysical approach to examine the effects of grasp type, carrying type, carrying material and carrying distance on maximum acceptable weights of carrying of male Taiwanese workers. This study recruited 14 carrying-experienced workers to participate in the experiment. The independent variables of this experiment were grasp type (power grip, hook grip), carrying type (touched-body, untouched-body), carrying material (solid, liquid) and carrying distance (4M, 8M). The dependent variables were heart rate difference (∆HR), blood pressure difference (systolic blood pressure difference, diastolic blood pressure difference), rating of perceived exertion (RPE) and the maximum acceptable weight of carrying (MAWC). The results showed : (1) the MAWCs and RPEs of power grip were greater than those of hook grip; (2) the MAWC of touched-body carrying type (13.5kg) was greater than that of untouched-body carrying type (12.3kg); (3) the MAWC of carrying liquid material was greater than that of carrying solid material, while the RPE of carrying liquid material was lower than that of carrying solid material; (4) the MAWC decreased with the increase of the carrying distance.
