Abstract：Objective: to evaluate the effects of low temperature on core Temperature, fat metabolism and sport ability of male athletes. Methods: the experimental method was adopted, the low temperature environment was 11℃ , the ambient temperature was 22℃ , and the relative humidity was 35% . 19 male undergraduate athletes participated in two times of power cycling exercise from incremental load to be exhaustive at low and normal temperatures respectively. The initial load was 30W, 20W was increased every 3minutes, and the rotational rotation rate was maintained at 65 rpm. In the process of sports, exhaled gas was continuously collected for the analysis of gas metabolism. Result: Under low temperature environment, the fat oxidation rate of exercise intensity within the scope of 40~75% VOmax was higher than that of normal temperature environment, the maximum fat oxidation rate (8.39±2.28 mg / min / kg) was higher than that of normal temperature environment (5.96±1.47 mg / min / kg), and the exercise intensity of maximum fat oxidation rate (56.3±3.1% VO2 max) was lower than that of normal temperature environment (65.6±2.4% VO2 max). At the same exercise intensity, the core temperature in low temperature environment was significantly lower than that in normal temperature environment, but the heart rate was significantly higher than that in normal temperature environment. Athletes’exercise time (24.3±7.6 min VS 22.6±7.2 min) and maximum output power (213±24 VS 208±26W) in low temperature environment were higher

摘 要：目的：评价低温环境对男运动员脂肪代谢、核心体温及运动能力的影响。方法：采用 实验法，低温环境为 11℃，常温环境为 22℃，相对湿度均为 35%。19 名男大学生运动员在低温 环境和常温环境，分别进行两次递增负荷至力竭的功率自行车运动，起始负荷为 30W，每 3min 增加 20W，维持转速 65 转/min；运动过程中连续收集呼出气体，进行气体代谢分析。结果：低 温环境下，运动强度在 40～75%VO2max 范围内的脂肪氧化率均高于常温环境，最大脂肪氧化 率（8.39 ± 2.28mg/min/kg）高 于 常 温 环 境（5.96 ± 1.47mg/min/kg），最 大 脂 肪 氧 化 率 的 运 动 强 度 （56.3±3.1%VO2max）低于常温环境（65.6±2.4%VO2max），相同运动强度时低温环境运动中的核 心体温显著低于常温环境，但心率显著高于常温环境。低温环境下运动员的运动时间（24.3± 7.6minvsVS22.6±7.2min）、最大输出功率（213±24WVS208±26W）高于常温环境。结论：低温环 境使男运动员运动中的脂肪代谢增强，降低核心体温，提高运动能力。 关键词：低温环境；运动员；脂肪代谢；核心体温；运动能力 中图分类号：G804.2 文献标识码：A 文章编号：1007-6204（2018）04-0047-05
