Key result
Low-load resistance training with blood flow restriction induced comparable increases in patellar tendon stiffness compared to high-load training (+25.2% vs +22.5%) over 14 weeks.
Why the study?
Despite comparable muscle adaptations between low-load resistance training with blood flow restriction and high-load training, little is known about tendinous adaptations after low-load blood flow restriction.
Does low-load resistance training with blood flow restriction induce comparable changes in patellar tendon properties compared to high-load resistance training in recreationally active males?

Absolute Event Rate: 25.2% vs 22.5%
p-value: p=not significant
Low-load resistance training with blood flow restriction induces comparable increases in patellar tendon stiffness and cross-sectional area as conventional high-load resistance training.

LL-BFR offers a viable alternative to high-load training for tendon adaptations; extends evidence supporting BFR efficacy in resistance protocols.
A 2021 study conducted an RCT in Healthy (recreationally active) (n=29). Low-load resistance training with blood flow restriction (LL-BFR) vs. High-load resistance training (70%-85% 1RM) was evaluated on Patellar tendon stiffness (p=not significant). Low-load resistance training with blood flow restriction induced comparable increases in patellar tendon stiffness compared to high-load training (+25.2% vs +22.5%) over 14 weeks.
