Key result
External compression with blood flow restriction at 150% of arterial occlusion pressure significantly increased 1RM maximal strength compared to no restriction (95.00 kg vs 91.87 kg, p < 0.01).
Why the study?
The study was conducted to evaluate the acute effects of external compression with blood flow restriction at 100% and 150% of full arterial occlusion pressure on maximal strength and strength-endurance performance during the bench press exercise.
Does external compression with blood flow restriction improve maximal strength and strength-endurance performance during bench press exercise in strength-trained men?
Population

High external compression with blood flow restriction at 150% of arterial occlusion pressure acutely increases maximal strength and endurance performance during bench press exercise.
Wilk et al. (2020) conducted an RCT in Healthy strength-trained men (n=12). External compression with blood flow restriction (BFR) vs. Without BFR (NO-BFR) was evaluated on 1 repetition maximum (1RM) in bench press (Cohen's d 0.19, p=<0.01). External compression with blood flow restriction at 150% of arterial occlusion pressure significantly increased 1RM maximal strength compared to no restriction (95.00 kg vs 91.87 kg, p < 0.01).
