Key result
A vigorous-intensity walking program during pregnancy decreased relative VO2 (-1.25, p=0.02) and VCO2 (-1.50, p=0.005) during submaximal exercise compared to a low-intensity program.

Vigorous-intensity walking yields greater aerobic efficiency gains in pregnancy; extends RCT evidence supporting intensity-dependent prenatal exercise benefits.

Does a vigorous-intensity walking program improve cardiorespiratory responses more than a low-intensity walking program in normal weight pregnant women?
p-value: p=0.02
A prenatal walking program of either low or vigorous intensity confers an aerobic conditioning benefit and is safe for mother and fetus, with vigorous intensity providing a greater response.
Ruchat et al. (2012) conducted an RCT in Pregnancy (n=44). Vigorous-intensity walking program vs. Low-intensity walking program (30% HRR) was evaluated on Change in relative VO2 and VCO2 during steady-state submaximal treadmill exercise (p=0.02). A vigorous-intensity walking program during pregnancy decreased relative VO2 (-1.25, p=0.02) and VCO2 (-1.50, p=0.005) during submaximal exercise compared to a low-intensity program.
