The effects of exercise and different types of sportswear on fluctuations of skin temperature were investigated and assessed by frequency analysis. Fifteen healthy women performed the wearing tests including 10- minute cycling exercise under the fixed circumstance of 25.0℃ and 14.3 mmHg vapor pressure.
　In all cases the peaks in the power spectrum were observed in the low frequency range. The amplitude of these peaks was obviously higher after, than before, the exercise. This tendency was especially noticeable at the back of the hand as compared with the results at the forehead or the forearm. The amplitude of peaks in the low frequency range was slightly higher when less body surface was covered with clothing. These data reflect the increased activity of thermoregulation as a result of exercise and ambient cool condition. It is considered that the influences of changes in these autonomic nervous systems were also shown in the rating of sensation.
