To characterize maternal thermal balance during pregnancy, the authors recorded the thermal response to moderate weight bearing exercise stress in four aerobically conditioned pregnant women. Studies were performed in a climate-controlled environment in each trimester of pregnancy and postpartum after modifying the exercise protocol for changes in maternal exercise condition. Core, vaginal, and mean skin temperatures were recorded at rest and during maximum exercise. Mean resting skin temperature increased during pregnancy; mean resting core and vaginal temperatures did not change. Core temperatures did not exceed 39C during exercise. Heat storage (heat content/kg) was not increased as a result of exercise with advancing pregnancy. According to these findings, thermal balance can be maintained with advancing gestation when exercise prescriptions are appropriately modified for conditioned women.
为了描述孕期母亲的热平衡状况，作者记录了四名有氧条件良好的孕妇在进行适度负重运动应激时的热反应。在孕期的每个阶段以及产后，在气候控制的环境中进行研究，并根据母亲运动状况的变化调整运动方案。记录静息状态和最大运动时的核心温度、阴道温度和平均皮肤温度。孕期静息平均皮肤温度升高；静息核心温度和阴道平均温度未发生变化。运动期间核心温度未超过39摄氏度。随着孕期进展，运动并未导致热储存（热含量/千克）增加。根据这些研究结果，对于条件良好的女性，适当调整运动处方，随着孕周增加可以维持热平衡。
