| 概要 | Purpose It is recently reported that determining sweat rate (SR) threshold for increasing galvanic skin conductance (GSC) would represent a maximum rate of sweat ion reabsorption in sweat glands. We evaluate the maximum rate of sweat ion reabsorption over skin regions, sex, and longterm exercise training by using the threshold analysis in the present study. Methods Ten males (2 untrained, 4 sprinters, and 4 distance runners) and 12 females (5 untrained, 4 sprinters, and 3 distance runners) conducted graded cycling exercise for 45 min at low, middle, and high exercise intensities (heart rate 100-110, 120-130, and 140-150 beats/min, respectively) for 10, 15, and 20 min, respectively, at 30 degrees C and 50% relative humidity. Comparisons were made between males and females and among untrained individuals, distance runners, and sprinters on the back and forearm. Results SR threshold for increasing GSC on back was significantly higher than that of forearm (P < 0.05) without any sex differences (back 0.70 +/- 0.08 and 0.61 +/- 0.04, forearm 0.40 +/- 0.05 and 0.45 +/- 0.06 mg/cm(2)/min for males showed higher SR threshold for increasing GSC than that of untrained subjects on back (P < 0.05) but not on forearm (back 0.45 +/- 0.06, 0.83 +/- 0.06, and 0.70 +/- 0.04, forearm 0.33 +/- 0.04, 0.49 +/- 0.02, and 0.39 +/- 0.07 mg/cm(2)/min for untrained subjects, distance runners, and sprinters, respectively). Conclusion These results suggest that the maximum sweat ion reabsorption rate on the back is higher than that of forearm without sex differences. Furthermore, exercise training in distance runners and sprinters improves the maximum sweat ion reabsorption rate on the back. |
