The present study was designed toward the development of high performance garments for sports. Seven healthy adult males pedalled a bicycle ergometer for 60 or 90 minutes, and a regional difference in sweating rate was examined in relation to work load, season and clothing. The regional difference was generally reduced in proportion to work load, and it was smaller in summer and in wearing on than that in winter and in seminude, respectively. The small difference was caused by an unexhausted sweating on the extremities, as compared with on the trunk. Skin temperatures were higher on the extremities than those on the trunk, when the regional difference in sweating rate was reduced. From these results, it was concluded that the regional difference in sweating rate might contribute to extend the adaptation for sports and exercise.
