Blood Flow Restriction training

great BFR presentation. A number of studies summarized in this presentation but basically he sussed out what the mechanism was for improving VO2max using BFR.

It’s not increased blood volume although they did find increased hormone response post-exercise…just no actual measurable difference in blood volume.

It’s not heart adaptation/increased stroke volume.

Turns out it’s rate of blood flow into and out of the muscle that increases.

Especially interesting results with the rowers. Yikes. (In case you missed it, the protocol used to achieve those results were 10 minute bouts at a 2mmol lactate. So very nominal exercise intensity. Some of those athletes were olympians. Amazing.)
