人的耐热能力与身体健康状况,有无其他慢性疾病,机体主要器官功能,特别是心血管功能好坏有关。为了预防或减少中暑发生,应对从事高温作业人员和热区部队指战员进行一般体检外,还应进行机体耐热能力的某种特殊检查。Wyndham提出不耐湿热人员的三项标准:最大氧摄取量少于2.5升/分;体重不足50公斤;年龄超过45岁。Pandolf建议用最大氧摄取量预测热习服速度。也有人用清晨体重预测高温劳动过程的脱水程度和耐热能力。我们拟通过高温人体实验,探讨心功能适应指数与耐热能力的关系,观察其是否可作为预测耐热能力或选拔高温作业人员的一个指标。方法实验对象为82名健康男战士,平均年龄
Human heat tolerance and physical health, with or without other chronic diseases, the main organ function, especially cardiovascular function is good or bad. In order to prevent or reduce the occurrence of heat stroke, the general medical examination should be carried out for the personnel engaged in hot work and the officers and soldiers of the hot-zone units, and a special inspection of the heat-resistant ability of the body should also be conducted. Wyndham presents three criteria for inhuman and hot subjects: maximum oxygen uptake of less than 2.5 liters / min; weight less than 50 kg; and over 45 years of age. Pandolf recommends using the maximum oxygen uptake to predict the rate of heat transfer. Some people use early morning weight to predict the degree of dehydration and heat resistance of high temperature labor process. We intend to use high-temperature human experiments to explore the relationship between the index of cardiorespiratory fitness and the ability to resist heat and observe whether it can be used as an index to predict the ability of heat-tolerance or to select the operators of high temperature. Methods The subjects were 82 healthy male soldiers, the average age
