Where Are Antigravity Muscles Located?

The most studied skeletal muscles which depend on gravity, "antigravity" muscles, are located in the posterior portion of the legs. Antigravity muscles are characterized generally by a different fiber type composition than those which are considered nonpostural.

Which muscles are antigravity?

Opposing the effect of gravity, the antigravity muscles help maintain an upright, balanced posture. These muscles consist of namely the soleus muscles, the extensors of the leg, the gluteus maximus, the quadriceps femoris and the muscles of the back.

What is antigravity muscle?

A muscle that acts, often through the stretch reflex, to counterbalance the pull of gravity and to maintain an upright posture. Many antigravity muscles have a high proportion of slow-twitch muscle fibres and are often called tonic muscles.
