The Claim
Increasing the angular velocity of ankle plantarflexion with the knee fully extended significantly increases muscle activation in the medial and lateral gastrocnemius while simultaneously decreasing activation in the soleus, demonstrating a velocity-dependent preferential recruitment of the gastrocnemius heads over the soleus.
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 you point your toes quickly with your knee straight, your outer calf muscles work harder while the deeper calf muscle works less. This means faster toe-pointing movements naturally target the outer calf muscles more than the deeper ones.
See the scientific wording
During ankle plantarflexions with the knee fully extended, increasing the angular velocity of movement significantly increases muscle activation in the medial and lateral gastrocnemius muscles while simultaneously decreasing activation in the soleus muscle. This velocity-dependent activation pattern suggests that faster plantarflexion movements preferentially recruit the gastrocnemius heads over the soleus when the knee is straight.
What the research says
1 studyWhen you point your toes quickly with your knee straight, your calf upper muscles work harder while the deeper lower muscle works less, showing that speed changes which calf muscles your brain chooses to activate.
