The Claim
Knee flexion at 30 or 60 degrees blunts the velocity-dependent activation responses of the medial gastrocnemius, lateral gastrocnemius, and soleus muscles during ankle plantarflexion, resulting in no significant changes in muscle activation as angular velocity increases.
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 your knee is bent at 30 or 60 degrees, moving your ankle faster doesn't make your calf muscles work any harder. This suggests that bending the knee acts like a stabilizer, keeping your calf muscle activity steady even when you change how fast you're moving.
See the scientific wording
When the knee is maintained at flexed angles (30 or 60 degrees), increasing the angular velocity of ankle plantarflexion does not produce significant changes in the activation levels of the medial gastrocnemius, lateral gastrocnemius, or soleus muscles. This indicates that knee flexion stabilizes or blunts the velocity-dependent activation responses typically seen in the calf muscles.
What the research says
1 studyWhen your knee is bent, changing how fast you point your foot does not change how much your calf muscles work. Bending the knee essentially turns off the usual speed-dependent muscle responses.
