The GASTROCNEMIUS 👯

#shorts
A few facts you might not know about this muscle:
📌 It’s the most superficial leg muscle
📌 In Greek it kind of means “the belly of the leg”
📌 Together with the Soleus, it creates a muscle called the Triceps Surae.
This muscle takes part in daily activities such as walking, running, sitting, standing up, etc.

Wow ! ..
This was quite phenomenal...
Exercises I haven't really done before... Thankyou

Very nice. Didn’t realize we used gastroc for knee flexion, but makes sense when you think about it.

[@ttb1513]

I did not realize that either. But after thinking about it, it does NOT make sense.
Consider, the primary action is listed as ankle plantar flexion. The gastro only does this if the knee is extended. When the knee is flexed, there is slack in the gastro muscle and it cannot provide force; only the soleus is used for plantar flexion when the knee is flexed.
Knee flexion is done by the hamstring. The gastro cannot unless the toes are kept raised (heel away from knee, toes up, ankle in dorsi flexion). But when are your toes ever raised when you want to use your calves to flex your knee (like this video states)? Never really. For example, when running your ankle goes in plantar flexion (toes down) and the heel is towards the knee, creating slack in the gastro (active muscle insufficiency), so the gastro cannot provide useful force to flex the knee.
Correct?

[@ttb1513]

Another way to dispel the notion that the gastro flexes the knee is to consider what happens when it contracts. For it to flex the knee, the heel has to NOT be pulled towards the knee (pointing the toes down). But what’s to stop the toes from just pointing down? Nothing.

[@ttb1513]

Ok, further consideration: the tibialis anterior (front of the shin), which is used for dorsi flexion, can provide the opposing force to keep the toes up and heel down, such that the gastro is stretched and can provide useful contracting force for knee extension.
Maybe somebody with expertise can confirm or explain this all well?
