| Summary: | 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.
