目的：为研究热环境对能量代谢的影响，对热区部队炎热季节的能量消耗率进行了测定。方法：用气体代谢法。结果：气温３０ ．３ ℃，室内静坐能量消耗率３ ．２７９ ｋ Ｊ／（ ｍ２·ｍｉｎ） ；气温３２ ．４ ℃，烈日下静坐能量消耗率３ ．５６９ ｋ Ｊ／（ ｍ２·ｍｉｎ） ，烈日下静坐高于室内静坐，但无统计意义（ Ｐ＞ ０ ．０５） 。气温３２ ．４ ℃，烈日下全装公路行军，能量消耗率为１８ ．１８１ ｋ Ｊ／（ｍ ２·ｍｉｎ） ，显著高于室内和烈日下静坐。热环境下徒手行军能量消耗率为１１ ．４２９ ｋ Ｊ／（ ｍ２·ｍｉｎ） ；轻装行军能量消耗率为１３ ．４５５ｋ Ｊ／（ｍ ２·ｍｉｎ） ；全装行军能量消耗率为１５ ．０３２ ｋ Ｊ／（ ｍ２·ｍｉｎ）（ 气温略低于以前全装行军） 。结论：热环境和军事劳动对能量代谢均有影响，但以军事劳动更为显著。
Objective: To study the effect of thermal environment on energy metabolism, the energy consumption rate of the hot-season troops in the hot season was determined. Methods: Gas metabolism method. Results: temperature 30. 3 ℃, indoor sit-in energy consumption rate 3. 279 k J / (m2 · min); temperature 32. 4 ℃, sit in the hot sun energy consumption rate 3. 569 kJ / (m2 · min), sit in the hot sun higher than the indoor sit-in, but no statistical significance (P> 0.05). Temperature 32. 4 ℃, full sun on the road under the march, the energy consumption rate of 18. 181 k J / (m 2 · min), significantly higher than indoor and sun-sitting. Unarmurized energy consumption rate of 11 in the heat environment. 429 kJ / (m2 · min); light march energy consumption rate of 13. 455k J / (m 2 · min); full march energy consumption rate of 15. 032 kJ / (m2 · min) (the temperature is slightly lower than the previous full march). Conclusion: The thermal environment and military labor have an impact on energy metabolism, but the military labor is more significant.
