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.

美國婦產科學院和加拿大的婦產科醫生協會發表了最新的孕婦活動指南，建議孕婦進行150分鐘中等強度運動以減少妊娠并發癥，有利于母體和嬰兒的健康。然而懷孕（嬰兒作為特殊負重）是如何影響孕婦的能量投入、活動體能和機械效率的卻了解很少。該研究通過FMS便攜式能量代謝儀來定量化不同運動程序的能量消耗和機械效率。
