摘要

尽管越来越多的认识到赛后运动性中暑(EHI)在赛马行业,报告的患病率是有限的。本研究的目的是调查日本赛马场的赛后EHI患病率和气候条件。1999年至2018年,在日本赛车协会(JRA)运营的比赛中,EHI的总体患病率为0.04%(975,247名参赛选手中有387例)。年患病率一直在上升,在研究期间的最后四年超过0.07%。夏季(5 - 9月)总患病率为0.086%(409,908例首发者352例)。10个JRA赛马场的月患病率在北纬34 ~ 43°N范围内,从无病例到0.459%不等。夏季赛马场月平均温度较高时,赛后EHI患病率较高。为了评估气候条件,我们调查了2017年7月和2018年8月晴朗赛马场上午9点至下午5点的全球湿球温度(WBGT,°C), 10个赛马场中EHI患病率较高。在这三个疗程中,WBGT在28至33°C之间的持续时间分别为测量分钟的95%,94%和65%。这一结果表明,在阳光明媚的夏季,三个赛马场的大部分比赛都是在温度在28 ~ 33℃之间进行的。这些发现可能有助于制定适当的对策,以便在每个研究的赛马场在炎热的天气中采取措施。

Prevalence of post-race exertional heat illness in Thoroughbred racehorses and climate conditions at racecourses in Japan.

Prevalence of post-race exertional heat illness in Thoroughbred racehorses and climate conditions at racecourses in Japan.

Prevalence of post-race exertional heat illness in Thoroughbred racehorses and climate conditions at racecourses in Japan.

Despite growing recognition of post-race exertional heat illness (EHI) in the horse racing industry, reports on its prevalence are limited. The purpose of this study was to investigate the prevalence of post-race EHI and climate conditions at racecourses in Japan. The overall prevalence of EHI from 1999 to 2018 was 0.04% (387 cases for 975,247 starters) in races operated by the Japan Racing Association (JRA). The yearly prevalence has been increasing, exceeding 0.07% in the last four years of the studied period. The overall prevalence in summer (May-September) was 0.086% (352 cases for 409,908 starters). The monthly prevalence varied among the 10 JRA racecourses, which are distributed from latitude 34 to 43°N, ranging from no cases to 0.459%. During summer, prevalence of post-race EHI was high when the mean monthly ambient temperature was high at a racecourse. To evaluate climate conditions, we investigated the wet-bulb globe temperature (WBGT, °C) from 9 AM to 5 PM on sunny race days in July and August of 2017 and 2018 at three racecourses with a high prevalence of EHI among the 10 racecourses. The durations of time during which WBGT was between 28 and 33°C at these three courses were 95, 94, and 65% of the minutes measured, respectively. This result indicated that most races on the sunny summer days were held when WBGT was between 28 and 33°C at the three racecourses. These findings could be useful in developing the appropriate countermeasures to be taken during hot weather at each of the studied racecourses.
