27 Preventing Muscle Atrophy with BFR

Owens Recovery Science

In this episode of the ORS podcast Johnny and the fellas discuss a recent paper that has given additional support to the ability of repeated inflations of a cuff limiting muscle atrophy from disuse. Here’s the paper: Kakehi, S., Tamura, Y., Kubota, A., Takeno, K., Kawaguchi, M., Sakuraba, K., Kawamori, R., & Watada, H. (2020).
