The Claim
In male bodybuilders, increasing hip flexion from 0° to 80° during leg extension exercise is associated with reduced T2 signal response in the proximal and middle regions of the rectus femoris muscle, suggesting lower metabolic stress and likely decreased muscle activation in these regions at higher hip flexion angles.
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 male bodybuilders do leg extensions with their hips more bent, the top and middle parts of their front thigh muscle don’t work as hard — they show less activity and fatigue compared to when the hips are straighter.

What the research says
1 studyThe study found that when bodybuilders did leg extensions with more hip bend, the upper and middle parts of their front thigh muscle were less activated, which matches the claim.
