| Summary: | 碩士 === 南台科技大學 === 工業管理研究所 === 100 === This study examined human physiological responses under different carrying tasks. This study recruited 16 males from factory workers who had at least 5 years of work experiences. The independent variables of this study were carrying weights (4.4 kg, 8.9 kg, 13.3 kg, 17.8 kg), carrying materials (liquid, solid) and carrying mode (vertical oriented container, horizontal oriented container). The dependent variables were participants’ hand grip force difference, heart rate difference, systolic blood pressure difference, diastolic blood pressure difference, and rating of perceived exertion (RPE). The results showed: 1. participants’ grip force difference, heart rate difference, systolic blood pressure difference, diastolic blood pressure difference, and rating of perceived exertion increased with the carrying weight; 2. the participants’ physiological cost of carrying liquid was greater than that of carrying solid; 3. the participants’ physiological cost of carrying a horizontal oriented container was greater than that of carrying a vertical oriented container; 4. the greatest RPE occurred at participants’ wrist and arms, followed low back and shoulder.
