Summary:The purpose of this study was to evaluate the effects of a thermal swimsuit (TSS) on body temperatures and thermal insulation during low and moderate intensity water exercise. Four healthy male subjects immersed in water (23℃) and pedaled on the underwater ergometer for 30 min. Each subject underwent the protocol with TSS and normal swimsuit (NSS) at two submaximal exercise intensities. During low intensity exercise esophagus temperature (Tes) was maintained baseline with TSS, while Tes decreased with NSS. Moderate exercise increased Tes with both swimsuits. Tissue insulation (I tissue) during moderate exercise were lower than that of low intensity exercise with both swimsuits. It might be caused by the higher blood flow due to increased exercise intensity. TSS decreased Itissue compared to NSS during moderate exercise. It might be due to attenuation of vasoconstriction in TSS-protected subjects. Suit insulation/total insulation and skin fold thickness showed a negative correlation. These suggested that TSS in cool water was especially useful for low fat subjects during low intensity exercise.
