This paper investigates how different combinations of clothing effect physical performance after warming up (W-up) at 15℃ air temperature. Four clothing types were studied with 6 male university soccer football players as the experimental participants. The four clothing types were : C) a uniform with short sleeved shirt and mid-thigh pants ; U) the uniform and W-up jacket with long sleeves ; L) the uniform and full-length W-up pants ; and UL) the uniform and full W-up suit. Rectal temperature, skin temperature (at 7 points), clothing microclimate, subjective sensations and body weight loss were measured for 40 minutes during W-up. Six kinds of physical performance were determined before and after W-up. Upperbody skin temperature was higher in case of combinations U and UL. Thigh and leg skin temperatures remained higher after W-up in case of combinations L and UL. Physical performance increased after W-up in case of all the combinations except C type. Lowerbody skin temperature as well as rectal and average skin temperatures had a high positive correlation with physical performance, and higher temperature indicated better performance. This suggests that lowerbody warming is related to the improvement of physical performance at this 15℃ temperature.
