Fiber is essential for digestion, heart health, and weight control. Here’s how it works — and how to get more from natural, whole-food sources.

A randomized controlled trial demonstrates that low-load blood flow restriction training (LL-BFRT) produces comparable improvements in quadriceps and hamstring strength to heavy-load resistance training during early rehabilitation following BPTB ACL reconstruction. No differences were observed in knee pain, joint swelling, or range of motion. These findings support LL-BFRT as a safe and clinically relevant alternative when high mechanical loading is not feasible.
