This work is taken up to evaluate the relationship between the thermal comfort of spectators and athletes and the prevailing meteorological conditions during Rio 2016 Olympic Games. Empirical and physiological thermal comfort indices are calculated from data collected from an automatic weather station installed near the Olympic Stadium and interviews with the spectators. The study period was marked by a gradual rise in air temperature and by the occurrence of two significant weather events associated with wind gusts, which caused disturbances in some areas of the competitions. ET and NET were below the air temperature, indicating that both humidity and wind contributed to the reduction of the human-biometeorological indices. Majority of the interviewed persons reported comfortable sensation and weather conditions. These perceptions corroborate results of the thermal comfort indices calculated for these resting spectators. The comfort indices calculated for the athletes with high level of physical activity showed that PET estimated hotter thermal sensation those for the individuals at rest, indicating that the physical type of a person may strongly influence the thermal sensation and comfort during intense physical activity. Increasing trend observed in all the indices of human thermal comfort during the period of study shows consistency among them.
本研究旨在评估 2016 年里约奥运会期间观众和运动员的热舒适感与当时气象条件之间的关系。通过安装在奥林匹克体育场附近的自动气象站收集的数据以及对观众的采访，计算出经验和生理热舒适指数。研究期间，空气温度逐渐升高，并且发生了两次与阵风有关的重大天气事件，这导致了部分比赛区域的混乱。ET 和 NET 低于气温，表明湿度和风速都导致了人体生物气象指数的降低。大多数接受采访的人都表示感觉舒适和天气状况良好。这些感知与为这些休息的观众计算出的热舒适指数结果相符。对于高体力活动水平的运动员计算出的舒适指数表明，PET 估计的热感觉比那些休息的人更热，这表明人的身体类型可能会强烈影响剧烈体力活动时的热感觉和舒适度。在研究期间，所有人体热舒适指数都呈现出上升趋势，这表明它们之间具有一致性。
