摘要
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:In order to study the effect of hot environment on energy metabolism, energy expenditure rate(EER) was measured in army men in tropical regions in hot summer. Methods: Gas metabolism method was used. Results: It was showed that EER of subjects sitting quietly indoors was 3.279 kJ/(m 2·min) at Tdb 30.3 ℃,EER of subjects sitting under burning sun was 3.569 kJ/(m 2·min) at Tdb 32.4 ℃,but there was no significant difference (P>0.05) between them. EER for marching with heavy load was 18.181 kJ/(m 2·min) under burning sun at Tdb 32.4 ℃,which was higher than that for sitting quietly indoors or sitting under burning sun. According to the load, the EERs of subjects marching in a hot environment were different. For example, the EERs of the subjects marching with unarmed,light and heavy load were 11.429 kJ/(m 2·min),13.455 kJ/(m 2·min) and 15.032 kJ/(m 2·min) respectively. Conclusion:Both hot environment and military labor could affect energy metabolism and the latter was more important than the former.
