RESISTANCE TRAINING DURING PREGNANCY ALTERS PLACENTAL CELLULAR COMPOSITION AND NUTRIENT TRANSPORT IN AN INTENSITY-DEPENDENT MANNER.

The resistance training during pregnancy can impact placental nutrient transport and consequently affect fetal growth and development. However, little is known about this exercise modality. According to the main guidelines, vigorous-intensity resistance training (RT) is not yet considered a safe activity due to the possible changes in uterine blood flow and oxygen and nutrient delivery. As a result, recommendations for RT still remain cautious for pregnant women.
