Abstract:Objective To explore the effect of heat acclimation training on people with high intensity physical activity in high temperature and humidity environment. Methods From August 2014 to August 2018, 70 amateur long-distance runners in Xianshan Community participate in 5 km long-distance training were divided into the oservation group and the control group by simple random grouping method, with 35 in each group. The observation group was received heat acclimation training before training. The changes of interleukin-1β (IL-1β), γ interferon (IFN-γ), tumor necrosis factor-α (TNF-α), acute physiology and chronic health evaluationⅡ (APACHEⅡ), glasgow coma scale (GCS), troponin I (cTnI), urine creatinine (Cr), creatine kinase isoenzymes (CK-MB) level. The incidence of exertional heat stroke, multiple organ dysfunction syndrome and the organ involvement rate in the two groups were compared. Results Before training, there were no significant differences in the levels of IL-1β, IFN-γ and TNF-α in the two groups (P > 0.05). After training, the IL-1β, IFN-γ and TNF-α levels in the two groups were increased than those before training, and the observation group was lower than the control group, with statistically significant differences (P < 0.05). Before training, there were no significant differences in APACHEⅡ and GCS scores between the two groups (P > 0.05). After training, APACHEⅡ scores of the two groups were increased than those before training, GCS scores were decreased than those before training, and APACHEⅡ scores of the observation group were lower than those of the control group, and GCS scores were higher than those of the control group, the differences were statistically significant (all P < 0.05). Before training, there were no significant differences in cTnI, Cr and CK-MB levels between the two groups (P > 0.05). After training, cTnI, Cr and CK-MB levels in the two groups were increased than those before training, the observation group was lower than the control group, with statistically significant differences (all P < 0.05). The incidence of exertional heat stroke, multiple organ dysfunction syndrome and organ involvement in the observation group were lower than those in the control group (P < 0.05). Conclusion Heat acclimation training has a significant effect on high intensity physical activity in high temperature and high humidity environment. It can effectively improve the inflammatory response and reduce the incidence of multiple organ dysfunction syndrome. It is worth popularizing and applying.
