Exercise is known to improve the health of the pregnant woman and her child. Studies that have evaluated physiological parameters during prenatal exercise have conflicting results. Better understanding of these physiological responses can modify exercise prescriptions, safety, and monitoring strategies. We examined the association between age, prepregnancy body mass index (BMI), gestational weight gain (GWG), and physical activity (PA) levels, factors that may influence a change in physiological (HR, VO₂ responses) and perceptual (RPE) responses to acute exercise throughout pregnancy.

体力活动和妊娠期体重增加可预测怀孕期间对运动的生理和知觉反应

众所周知，运动可以改善孕妇及其孩子的健康。评估产前运动期间生理参数的研究得出了相互矛盾的结果。更好地了解这些生理反应可以修改运动处方、安全性和监测策略。我们检查了年龄、孕前体重指数 (BMI)、妊娠期体重增加 (GWG) 和体力活动 (PA) 水平之间的关联，这些因素可能会影响生理（HR、VO ₂反应）和感知 (RPE) 的变化对整个孕期急性运动的反应。
