A randomized controlled trial on the effects of antenatal exercise on birth weight and neonatal body composition.

Methods We are conducting a parallel arm randomized controlled clinical trial in Auckland, New Zealand (NZ). Eligible participants were enrolled to the study from March 2013 to April 2014. The intervention group participated in a 16-week home-based moderate-intensity exercise programme utilising stationary cycles and heart rate monitors. Maternal measures including weight, aerobic fitness, physical activity and diet were assessed at baseline and end of intervention. Neonatal and maternal body composition were assessed 14 days after delivery.
