The Claim
Fixing the knee at flexed angles impairs the selective recruitment of motor units in response to movement speed, resulting in inhibition of the gastrocnemius and facilitation of the soleus, thereby demonstrating that knee joint position acts as a neuromodulator that constrains velocity-dependent neuromuscular recruitment strategies in the lower leg.
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.
Bending your knee and holding it in place changes how your leg muscles fire, slowing down the calf muscle that points your foot down while speeding up the one that helps you stand on your toes. Basically, the angle of your knee changes how your brain tells your leg muscles to work during movement.
See the scientific wording
Fixing the knee at flexed angles weakens the body's ability to selectively recruit motor units based on movement speed, creating an inhibitory effect on the gastrocnemius muscles and a facilitative effect on the soleus. This suggests that knee position acts as a neuromodulator that constrains velocity-dependent motor unit recruitment strategies in the lower leg.
What the research says
1 studyBending your knee while pushing off with your foot changes how your calf muscles work, specifically reducing the speed-sensitive control of the upper calf muscles while boosting the lower calf muscle. This shows that just changing your knee angle can directly alter how your nervous system activates leg muscles.
