0 the outer calf muscle that goes from the back of the knee to the heel -- （拉丁语，用于医学术语中）腓肠肌
Leg cramps cause shortening of the gastrocnemius muscle in the calf. 腿部痉挛引起小腿腓肠肌收缩。
The more that the feet are forced into this position, the more it may cause the gastrocnemius muscle (part of the calf muscle) to shorten.
It is fully activated only with the knee extended because the gastrocnemius is shortened during knee flexion.
Recordings from lateral gastrocnemius-soleus extensor nerve and tibialis anterior flexion nerve were taken to demonstrate this control scheme.
In vivo physiological cross-sectional area and specific force are reduced in the gastrocnemius of elderly men.
Lower leg muscles acting on the ankle are the dorsiflexors (tibialis anterior) and plantarflexors (gastrocnemius and soleus).
As in humans it is the insertion of the gastrocnemius and superficial digital flexor tendons.
When walking in negative heeled shoes, muscle activity of gastrocnemius and tibialis anterior muscles are similar to that observed in uphill walking.
Muscle force, specifically in the gastrocnemius and/or soleus, may limit walking speed in certain populations and lead to slower preferred speeds.
