典型应用二

Greater energy demand of exercise during pregnancy does not impact mechanical efficiency，Denize K M, Akbari P, da Silva D F, et al. Applied Physiology, Nutrition, and Metabolism, 2019.

美国妇产科学院和加拿大的妇产科医生协会发表了最新的孕妇活动指南，建议孕妇进行150分钟中等强度运动以减少妊娠并发症，有利于母体和婴儿的健康。然而怀孕（婴儿作为特殊负重）是如何影响孕妇的能量投入、活动体能和机械效率的却了解很少。该研究通过FMS便携式能量代谢仪来定量化不同运动程序的能量消耗和机械效率。
