Abstract
In the present report, effects were investigated of four kinds of underwear, those with foundations of three different fits and with no foundations, on the subjects' states of fatigue, physical functions and on their various kinds of work efficiency.
Results are as follows:
1. Fricker Test shows no difference in the clothing.
2. A foundation smaller than the actual measurement in girth by 15cm is too tight, considering the subject's mounted pulse at short periods of work and its states of recovery.
3. Regarding kinds of work efficiency examined here, foundations of a proper fit achieve the effect of increased efficiency.
