Huang, J-H, Chiu, Y-C, and Chang, C-K. The influence of hot environment on pitching and hitting performance in professional baseball. J Strength Cond Res 35(11): 3251-3255, 2021-Baseball is usually played outdoors during the warmest months of the year. The long exposure to a hot environment may lead to hyperthermia and subsequent impaired cognitive function, which is crucial for hitting and pitching performance in baseball. The purpose of this study was to investigate the effect of apparent temperature on pitching and hitting performance in Chinese Professional Baseball League games in Taiwan. Each pitched and batted ball from a total of 480 regular season games in 2018 and 2019 was analyzed. Each game was categorized into one of the 4 groups on the basis of the average apparent temperature at which it was played: cold (below 21° C), warm (21-28° C), hot (28-34° C), or extremely hot (above 34° C). Differences in pitching and hitting variables were compared across the 4 groups. In the extremely hot environment, slugging percentage, isolated power, base on balls per 9 innings, home runs per 9 innings, and walks plus hits per inning were all significantly higher than those in the other 3 environments. The results suggest that offensive production was significantly increased in extremely hot environments in the Chinese Professional Baseball League. It is recommended that pitchers could adopt cooling interventions to alleviate the decline in performance in an extremely hot environment.
黄，J-H，邱，Y-C，和常，C-K。热环境对职业棒球投球和击球表现的影响。J 力量与调节研究 35（11）：3251-3255，2021-棒球通常在一年中最温暖的月份在户外进行。长时间暴露在炎热的环境中可能导致体温过高，随后认知功能受损，这对棒球的击球和投球表现至关重要。本研究的目的是调查中国职业棒球联赛比赛中表观温度对投球和击球表现的影响。对 2018 年和 2019 年共 480 场常规赛的每个投球和击球球进行了分析。根据比赛时的平均表观温度，每场比赛分为 4 组之一：冷（低于 21°C）、温暖（21-28°C）、热（28-34°C）或极热（高于 34°C）。比较了 4 组之间的投球和击球变量差异。在极热环境中，打点率、孤立功率、每 9 局保送、每 9 局本垒打和每局安打加保送都显著高于其他 3 种环境。结果表明，在中国职业棒球联赛中，极热环境下进攻产量显著增加。建议投手可以采取冷却干预措施，以减轻极热环境下表现的下降。
