     We compared wet-bulb globe temperature (WBGT) as an integrated index of the thermal environment in outdoor and indoor sports activities. Measurements of globe temperature, relative humidity and air temperature for calculating WBGT were made every 30 minutes during the practice of women’s softball and volleyball teams at Osaka Int’l University from April to November. There were no significant group differences in WBGT between indoor and outdoor sports activities from the beginning of July to the middle of September. However, the globe temperature (during July - September) and air temperature (during August) were significantly higher outdoors than indoors. The relative humidity (during July and August) was significantly higher indoors than outdoors. These results suggest that countermeasures against the increases of humidity during indoor sports activity and of solar radiation during outdoor sports activity should be taken to prevent heat disorders
