Summary

Despite the increase in numbers of women who engage in heavy, free-weight resistance exercise training (e.g. powerlifting, weightlifting, cross fit), the knowledge on how such exercise may affect fertility, pregnancy and birth outcomes is poor. Based on observational and associational studies of pregnant women in labour, recommendations are not to lift more than 11 kg in external load after mid-term, or to lift more than a total of 100 kg during a day. Ignoring such recommendations is associated to increased risk of miscarriage and preeclampsia, and of low birthweight and premature birth, respectively. As such, fit women who continue to exercise during pregnancy, are met with scepticism and warnings, resulting in shame and insecurity. Such attitudes may also result in physical inactivity during pregnancy, being on the contrary of what is recommended for a healthy pregnancy and delivery. Elite athletes may additionally be deprived from an early return to sport if not being able to keep exercise intensity close to pre-pregnancy period. With poor knowledge on how fit, strong women respond to high external loads during pregnancy exercise, recommendations are to follow the general guidelines.

The aim of this observational study, is to explore how regular resistance exercise training may affect fertility, and how high external loads in resistance exercise training during pregnancy in resistance trained women affect; a)their pregnancy and birth outcome, and b)health of the women and their children up to 12 months post-delivery.
