Key result
Low-load resistance training with blood flow restriction during 30 days of limb suspension attenuated losses in knee extensor cross-sectional area (1.2% vs 7.4%) and strength (2.0% vs 21%).

May attenuate unloading-induced muscle loss; hypothesis-generating and requires RCTs before practice change.

Low-load resistance training with blood flow restriction effectively maintains knee extensor muscle strength and size during 30 days of muscular unloading.
Cook et al. (2010) studied Muscular unloading (n=16). Low-load resistance training with blood flow restriction (LL(BFR)) vs. No exercise was evaluated on Loss in knee extensor cross-sectional area (p=<=0.05). Low-load resistance training with blood flow restriction during 30 days of limb suspension attenuated losses in knee extensor cross-sectional area (1.2% vs 7.4%) and strength (2.0% vs 21%).
