Abstract
To investigate the difference of work intensity with a hatchet from a saw, 4 male subjects performed sham pruning in the laboratory. A surveying pole was supposed to be a tree with branches at the height of 40,120,and 200cm. At each work, expired gas was analyzed and heart rate was measured. The oxygen uptake of the work with a hatchet was significantly higher than that of the work with a saw. Moreover, between the works with 2 kinds of tools, significant differences were observed on the inspired gas volume, the fraction of expired CO_2,and the volume of expired CO_2. To discriminate the data with hatchet and saw, linear discriminant function with 11 variables was obtained which were correspond to measured 11 items on sham pruning. The variables which contributed largely to discrimination were RQ, O_2 uptake, expired CO_2 volume, and inspired gas volume; these were the items which reflected work intensity.
