热环境对水溶性维生素代谢的影响研究较多,但结果不尽一致。本实验是在人工湿热气候下负重步行,肛温升高到39℃以上 2小时出汗量超过1.2升时,观察维生素B_1、B_2、C代谢的变化。试验方法受试者为11名健康男子(31.1±0.3岁),在WBGT35.6℃(DB 37℃、WB34℃、RH80％、WS0.14～0.8m/sec、GB40.5℃)的湿热气候室内,穿的确凉旧军服负重12.5kg,以时速4.5km步行2hr(中间休息10min)。预先饮水500ml,热暴露时分次饮水1000ml,
The impact of thermal environment on the metabolism of water-soluble vitamins more, but the results are not consistent. In this experiment, we carried on the walk with weight in artificial damp-heat climate, and observed the changes of vitamin B 1, B 2 and C metabolism when the rectal temperature increased to above 39 ℃ for 2 hours and the amount of sweating exceeded 1.2 liters. Test Methods Subjects were 11 healthy men (31.1 ± 0.3 years) with a wet and hot climate at WBGT of 35.6 ° C (DB 37 ° C, WB 34 ° C, RH 80%, WS 0.14-0.8 m / sec, GB 40.5 ° C) Indoor, wearing really cool old uniforms weighing 12.5kg, 4.5km speed walk 2hr (the middle of rest 10min). 500ml of pre-drinking water, heat exposure times 1000ml of drinking water,
