Abstract：
In this study, we evaluated the thermal environments of different tennis courts using wet-bulb globe temperature (WBGT) meters. WBGT meters were installed in an outdoor hard court, sand-filled artificial grass court, and clay court (a softball field), and measurements were taken hourly from 9:00 to 17:00 on weekdays from June 1 to September 21, 2022. The results were compared with data from different courts and the nearest Japan Meteorological Agency station (JMA WBGT) based on the Japan Sports Association\'s guidelines for exercise to prevent heat stroke. The median WBGT on each court was significantly higher for hard courts at the \"Warning\" (25 ≤ JMA WBGT < 28) level or above, sand-filled artificial grass courts at the \"Severe Warning\" (28 ≤ JMA WBGT < 31) level or above, and clay courts at the \"Danger\" (31 ≤ JMA WBGT) level than the JMA WBGT. Compared with the JMA WBGT, hard and sand-filled artificial grass courts are played on under particularly hot conditions. The results of this study could indicate to tournament organizers and coaches the importance of measuring the WBGT on each court surface from an early stage to prevent heat-related incidents.
摘要：
在这项研究中,我们使用湿球温度（WBGT）表评估了不同网球场的热环境。WBGT仪表安装在室外硬地球场，充满沙子的人造草地球场，和红土球场（垒球场），并在2022年6月1日至9月21日的工作日从9:00到17:00每小时进行测量。根据日本体育协会预防中暑的运动指南，将结果与来自不同法院和最近的日本气象厅站（JMAWBGT）的数据进行了比较。在“警告”（25≤JMAWBGT<28）或以上的硬地球场上，每个球场的WBGT中位数明显更高，“严重警告”(28≤JMAWBGT<31)水平或以上的填沙人造草地球场，和红土球场的“危险”级别（31≤JMAWBGT）高于JMAWBGT。与JMAWBGT相比，坚硬和充满沙子的人造草地球场在特别炎热的条件下进行。这项研究的结果可以向锦标赛组织者和教练表明，从早期阶段开始测量每个球场表面上的WBGT以防止与热有关的事件的重要性。
