Effects of Clothing on Thermoregulatory Responses During Fencing Practice in a Hot Environment
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.21 Vol.21】
This study was performed to analyze the effects of clothing on thermoregulatory responses during fencing practice in hot environments.
In experiment No.1, sweat rate, and fluid intake of college-aged male fencers (n=16) were measured during practice sessions held on several hot summer days under two conditions, i.e., with two different sets of clothing, T-shirts and short trunks (TS) and fencing uniforms (FU). During practice, fencers performed fundamental actions and footwork, wearing TS, and also performed matches and lessons with a saber, wearing FU. The fencers were allowed free access to a sports beverage during the practice sessions. The environmental conditions (wet-bulb globe temperature, WBGT [℃]) varied during the study, with temperatures ranging from 17.2 to 29.1℃.
Sweat rate and fluid intake during practice with both TS and FU increased according to the increase in WBGT, and sweat rate with the FU was significantly higher than that with the TS when WBGT was lower than 27℃.
In experiment No.2, the heart rate, rectal temperature and chest skin temperature were measured in college-aged male fencers (n=6) during practice with both TS and FU on several hot summer days. Heart rate response was similar between TS and FU. Rectal temperature and chest skin temperature during practice was significantly increased according to the increase in WBGT, and these temperatures were significantly higher with the FU than with the TS.
These results suggest that thermal stress is higher with the FU than that with the TS during fencing practice in a hot environment.
