本文以实验室研究与现场验证相结合,观察了高温长跑锻炼对人体的适应性影响。实验室研究长跑组和对照组各15人,现场验证各20人。锻炼期前后,全部受试者各进行一次热应激标准试验。结果显示,锻炼组直肠温度、股温、心率、出汗量、心肌氧耗指数,K值,疲劳症状发生率和RPE较锻炼前均显著降低,全血乳酸含量和血压变化明显改善,而Vo_2max和PWC170大大增加。但对照组变化不大。高温长跑锻炼能够明显提高耐热力、体力和延缓疲劳。
In this paper, a combination of laboratory research and field verification, we observed the adaptability of high-temperature long-distance exercise to the human body. Laboratory study of long-run group and control group of 15 people, the field validation of 20 people. Before and after the exercise period, all subjects underwent a standard test of heat stress. The results showed that rectal temperature, femoral head temperature, heart rate, sweating volume, myocardial oxygen consumption index, K value, the incidence of fatigue symptoms and RPE were significantly lower than those before exercise, and the whole blood lactate content and blood pressure were significantly improved. And PWC170 greatly increased. But the control group changed little. High-temperature long-distance exercise can significantly improve heat resistance, physical strength and delay fatigue.
