AGONIST MUSCLES AND ANTAGONISTS: DIFFERENCES
All runners recognize the importance of the muscles to run and perform at their best.

Your body is full of muscles that allow movement: in your arms there are muscles, in your legs too, and not to mention the feet and hands.

Among runners it is very normal to know the names of the most important muscles (mainly those of the legs) and their location.

However, few people know the difference between agonist and antagonist muscles.

Let’s know the details!

The antagonist and agonist muscles work in pairs to perform a wide range of movements and actions .

Basically, the difference between antagonist and agonist muscles is that they work in the opposite direction to complete an action.

➤ The keys to understanding these concepts
✓ Depending on the movement required, a muscle can be an agonist in one movement and antagonist during another action.

✓ The agonist muscle always contracts to initiate movement and the antagonist stretches and lengthens to allow movement.

✓ To return the body part to its normal position , the agonist muscle that initiated the original movement will have to become the antagonist to allow the original antagonist muscle to contract and return to the normal position.

✓ A muscle can only be referred to as an agonist in relation to a movement or other muscle.

It is never appropriate to call a muscle an agonist unless we describe its function in a movement or refer to it in relation to an antagonist. Saying “the biceps is an agonist” is incorrect or at least incomplete .

The simplest examples of agonists and antagonists
In your body, there are some pairs of antagonist and agonist muscles that will help you fully understand how it works.

SUPERIOR LIMBS
In your arms, the biceps and triceps work together to allow a good part of the movements of your arm.

ANTAGONIST AGONIST

So, when you flex your arms, your biceps works as an agonist and triceps as an antagonist.

To extend your arm, the roles are inverted and the biceps become antagonists and the triceps become agonists.

LOWER EXTREMITIES
In your legs , the operation of the quadriceps and hamstrings is similar when you flex the knee.

In addition to the agonist and antagonist muscles , other muscles also contribute to your movements helping with their activation (synergists), contracting isometrically to immobilize neighboring joints (fixators) and others provide important support during exercise to prevent injury and restrict the movement (neutralizers).

Each one of the muscles of your body is important and has different functions when moving.

The important thing to know this distinction lies in the fact of becoming aware of the importance of working on the strengthening and care of each of the muscles of your body and in different ways.

more intensely trained than others, usually in function of fashions or aesthetics (for example biceps or abdominals when the good weather arrives) or simply because of ignorance or little information . This specific work of a muscular zone involves the imbalance of forces that can cause greater wear on the joints, as well as overloads on tissues, which not only is not beneficial for muscle development but also increases the risk of injury.

The antagonist musculature refers to the muscle structure and its function, that is, different muscle groups that contract and relax , whenone is “active” the other remains “passive” . Any movement will use a group of muscles in said execution, and in turn, for the movement in the opposite direction or angle, there will be others involved.

The work of the antagonist musculature is fundamental to avoid stagnation in our training and in the stabilization process of the joint. When we talk about this type of exercises, we usually resort to the term “superseries”, consisting of restlessly chaining several muscle areas and their muscle groups antagonists.

When an exercise is performed for a muscle group and then another exercise for the antagonist muscle group, the strength development is greater for the second exercise. This is due to the proprioceptive system.

In short, we can draw several positive conclusions from the antagonistic exercises:

We save time. We can do a session in much less time taking advantage of the rest period as an active period.
Massive loss of fat, being high intensity exercises, which supposes a great energy demand.
We correct muscular decompensation. Neglecting the antagonist muscle, in the long run, we can generate those decompensations that pose a risk of injury.
Greater efficiency. If in the rest period of a muscle group we work its antagonistic, we generate a blood reflux motivating cellular oxygenation.
