Rush labor contains different types of physical works, and each work load, when classified in accordance with Christensen's criteria, was mainly classified as being moderately heavy or heavy in the planting process, and being moderately he. avy or very heavy in the harvesting process and light in the weaving process.
The average value of relative metabolic rate for working time was estimated to be 3.0±0.2 (4.74 kcal/65kg/min) for males, 2.9±0.1 (3.63 kcal/55kg/min) for females at planting. And 3.6±0.2 (5.43 kcal/65kg/min) for males, 3.8±0.1 (4.43kcal/55kg/min) for females at harvesting, 1.6±0.4 (3.12 kcal/65 kg/min) for males, 1.2±0.1 (2.11kcal/55 kg/min) for females at weaving.
The average value of energy expenditure a day was calculated to be 3619±313 kcal for males and 3023±277 kcal for females at planting, 4346±228 kcal (115% of caloric intake) for males, 3803±235 kcal (158%) for females at hervesting, 2560±221 kcal for males, 2178±86 kcal for females at weaving.
