This study investigated thermal swimsuits (TSS) effects on body temperature and thermal insulation of prepubescent children during moderate-intensity water exercise. Nine prepubescent children (11.0±0.7yrs) were immersed in water (23℃) and pedalled on an underwater cycle-ergometer for 30min with TSS or normal swimsuits (NSS). The rectal temperature (T_<re>) was maintained slightly higher with TSS than with NSS. The total insulation (I_<total>) was significantly higher with TSS. The 〓T_<re>, 〓mean body temperature (T^^-_b), and tissue insulation (I_<tissue>) in the NSS condition were correlated with % body fat, which indicated that the insulation layer of subjects with low body fat was thinner than that of obese subjects, and tended to decrease body temperature. Wearing TSS increased I_<total>, thereby reducing heat loss from subjects' skin to the water. Consequently, subjects with TSS were able to maintain higher body temperatures. In addition, TSS is especially advantageous for subjects with low body fat to compensate for the smaller I_<tissue>.
