The Claim
In healthy adult males, tetanic quadriceps torque is significantly higher in the supine position (111 ± 31.9 Nm) compared to the seated position (99 ± 27.5 Nm), indicating greater intrinsic muscle force capacity when the hip is extended and the rectus femoris muscle is in a lengthened state.
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 healthy guys lie on their back, their thigh muscles can push harder than when they're sitting — probably because the position stretches one key muscle and lets it work better.

Tetanic quadriceps torque is higher in the supine position (111 ± 31.9 Nm) than in the seated position (99 ± 27.5 Nm) in healthy adult males, suggesting greater intrinsic muscle force capacity when the hip is extended and rectus femoris is lengthened.
What the research says
1 studyThe study measured leg muscle strength in two positions and found it was higher lying down than sitting, just like the claim says.
