Out of the 800 or so muscles in the human body there are only a few that are defined as antigravity muscles:

Abdominals

Erector Spinae

Gluteus Maximus

Hip Flexors

Quadriceps

Hamstrings

Gastrocnemius

Soleus

Tibialis Anterior

Brian Carpenter Thank you for your answer.

Could you please tell me are the following upper limb muscles defined as anti-gravity muscles or not?

• Arm adductors
• Elbow flexors
• Elbow extensors
• Wrist flexors
• Wrist extensors
• Finger flexors

No, no, no, no, no.

To all:

I am pondering this question as to what is meant by anti-gravity.

There is no muscle to my knowledge (or group of muscles or any compartment of muscles that can negate the amazing forces of gravity and grf.

So,

do you mean muscles that prevent foot and postural collapse or

elevation from the floor while still in contact with the floor or

elevation off the floor?

Dennis Shavelson Anti-gravity muscles hold your body up against gravity. 

Antigravity muscles (sleeping muscles) go through the entire human body in the form of thin whitish fibers [1].

Antigravity muscles act as strings in the body. They come from under the feet, upwards the legs, through the body, the hands, the internal organs, vessels and into the brain, making it a whole system [1].

The role of the antigravity muscles

Antigravity muscles are responsible for three functions:

- Preservation of body shapes,

- Movement speed formation,

- Exactness of body reaction.

- Balance control [2]

Dewan:

I sense you are referring to the myofascial organ, a poorly high level evidenced structure only now, coming into its own when you speak of "anti-gravity muscles"

and

I hope you are not insulted by my being frank and to the point.

We are 98% water and without the myofascia, we would be a puddle.

Consider reviewing my article on Resistance Training . It may give you a better foundation on this subject: Article Resistance Training: A Meta-Analysis of the Current EBM

What that has to do with gravity is a red herring to me and calling it muscle is concerning to me.

Perhaps you could explain further.

In the context of space physiology, the term antigravity muscles is normally used for the muscles that have to primarily work to maintain upright stance and are most important for movements such as jumps where you have to work against gravity. That would include most of the muscles Brian mentioned, but primarily the leg extensors and not the flexors (although of course they are also involved, but to a lesser extent). The term antigravity is not well defined, it is more of a concept to explain that these muscles are most affected during spaceflight, as they no longer have to work against the force of gravity and will atrophy much more than other muscles, for example leg flexors or the muscles of the upper extremity.

during flexion position.

Take a look at Figure 4.1 of this document: ===> https://chiro.org/ACAPress/Body_Alignment.html

In reality, the muscles illustrated in Figure 4.1 serve to impact the skeletal bones to impact them to form a single bony unit functionally.

Once impacted, the bones support themselves.

I would not cause these muscle engine anti-gravitational.

Peroneus longus, the pronator of the forefoot is the only true anti-gravity muscle in the body because when it is inhibited or exhausted, the entire posture collapses.

To illustrate thet the neck flexors and extensors and others are anti-gravity muscle engines is a stretch, n'est pas?
