Description
Summary:This study investigated multiple effects of the environmental condition, physical characteristics, and swimwear condition on children's thermal sensation (TS) during elementary school swimming class. Sixth-grade elementary children (n=68) participated in a swimming class for 8 times. They wore normal swimsuit or thermal swimsuit. Multiple regression analysis was performed to make estimation equation of TS. The following two regression equations were developed. The equations contain 3 predictors of water temperature (T?), swimwear condition (Suit), and physical characteristics (surface area per body weight：SA/BW or BMI). (Ts=0.58Tw+ 1.21 Suit -126.2 SA/BW -11.3, TS=0.58Tw+1.21 Suit +0.139 BMI -17.8). The result of standardized regression coefficients indicated that, T? was the greatest contributor to TS, followed by Suit, and physical characteristics. We defined thermally comfortable area when TS is at the range from -0.5 to +0.5, and showed the relationships between physical characteristics (SA/BW or BMI) and T?, calculated from the equations when TS=-0.5 or +0.5, in each swimwear condition.
