The Claim
In male bodybuilders, a hip flexion angle of 40° during leg extension exercise is more effective than 80° for targeting the proximal region of the rectus femoris, as indicated by greater T2 signal increases observed at the moderate angle.
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.
For male bodybuilders doing leg extensions, bending the hips to 40 degrees might work the top part of the front thigh muscle better than bending to 80 degrees, based on brain scan-like results showing more muscle activity at the smaller angle.

What the research says
1 studyThe study found that bending the hips to 40 degrees during leg extensions activates the upper part of the front thigh muscle more than bending to 80 degrees, which matches what the claim says.
