BFR is becoming a focus on much research due to its effectiveness at eliciting muscle growth, strength and cardiovascular benefits with low intensity training which is relevant post injury, surgery, overtraining, and elderly when moderate to heavy training may need to be avoided for various individual risk reasons.
BFR depending on how programmed can also help within the healthy population but should still be viewed through the lens of outcomes where considerations are made to each individual participant.
Weight training while pregnant is becoming more common place with many moms demonstrating true athleticism during this beautiful process of brining a new life into the world. Where BFR specifically fits around this conversation has everything to do with safety to the mom and the baby.
Expecting moms should be encouraged to stay active and consider intensity changes as they progress due to either blood pressure changes, blood sugar, and obviously body changes as the baby grows.
Because there is a normal increase in blood pressure during pregnancy, adding BFR May not make the most sense as it can also elevate blood pressure by artificially increasing peripheral resistance of what we call systolic blood pressure. For some mother’s preeclampsia or excessive blood pressure is a risk and many times forces some moms to manage their blood pressure through activity modification and some safe over the counter drugs. Because research into pregnancy with BFR will likely be difficult it will likely stay contraindicated or restricted.
Equally, BFR has demonstrated to increase In anabolic hormones (testosterone, IGF-1, GH) through above normal levels of metabolic stress (greater than what is seen with lite to moderate loading) we are just unfamiliar of how this can effect the growing baby.
Do no harm everyone. Promote active, healthy, and strong moms.
