The Claim
Do squats without full knee extension cause more muscle hypoxia than locked squats under blood flow restriction?
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When you do squats without fully straightening your knees and restrict blood flow, your thigh muscle gets much less oxygen during the exercise than when you're just sitting still.
See the scientific wording
During blood flow-restricted squatting, non-locked squats performed for 12 seconds produce a significantly lower minimum tissue oxygen saturation (StO2) in the vastus lateralis muscle compared to resting levels, indicating greater intramuscular hypoxia.
What the research says
1 studyThe study measured StO2 via NIRS during controlled squat conditions under BFR and found a statistically significant drop in oxygen saturation only in the NL12 condition compared to rest, directly supporting this observation.
