Overactivity in one muscle of the agonist-antagonist pair and eventual desirability in athletes?

What happens in an antagonistic pair when one muscle contracts?
Muscles work in ‘antagonistic muscle pairs’. One muscle of the pair contracts to move the body part, the other muscle in the pair then contracts to return the body part back to the original position. Muscles that work like this are called antagonistic pairs.
What is agonist and antagonist in sports?
The muscle that is contracting is called the agonist and the muscle that is relaxing or lengthening is called the antagonist. One way to remember which muscle is the agonist – it’s the one that’s in ‘agony’ when you are doing the movement as it is the one that is doing all the work.
What would happen if both agonist and antagonist contracted at the same time?
Muscle coactivation occurs when agonist and antagonist muscles (or synergist muscles) surrounding a joint contract simultaneously to provide joint stability. It is also known as muscle cocontraction, since two muscle groups are contracting at the same time.
What is an example of an agonist and antagonist muscle pairing?
For example, when you perform a bicep curl, the biceps will be the agonist as it contracts to produce the movement, while the triceps will be the antagonist as it relaxes to allow the movement to occur.
How might injury to one of the muscles in an antagonistic muscle pair affect movement?
How might injury to one of the muscles in an antagonistic muscle pair affect movement? The injury would allow for the joint the muscles are attached to, to move in one direction… either only up becasue the lower muscle was damaged…or only down because the top muscle of the pair was damaged.
What is it called when one muscle contracts the antagonist muscle relaxes this is referred to as?
In an antagonistic muscle pair as one muscle contracts the other muscle relaxes or lengthens. The muscle that is contracting is called the agonist and the muscle that is relaxing or lengthening is called the antagonist.
Antagonistic muscle pairs.
| Biceps | Triceps |
|---|---|
| Pectoralis major | Latissimus dorsi |
Why are agonist and antagonist muscles important?
The efficient coordination of agonist and antagonist muscles is one of the important early adaptations in resistance training responsible for large increases in strength. Weak antagonist muscles may limit speed of movement; consequently, strengthening them leads to an increase in agonist muscle movement speed.
When joint movement is the result of antagonistic muscle pairing?
When joint movement is the result of antagonistic muscle pairing, movement is accomplished by opposite action of the paired muscles.

What are the agonist and antagonist muscles in a push up?
Among the many muscles you work during this movement are the pectorals, the front shoulders and the triceps. These muscles are known as the agonists, and they contract to allow you to do a pushup. Other muscles resist and/or counteract your movements; these are known as antagonists.
How do muscles change from agonist to antagonist?
The two muscles in an antagonistic pair are in opposition. That is, if one extends a limb during its contraction, the other will return the limb to its original position when flexed. In each pair, depending on the movement, one muscle plays the role of the “agonist” and the other muscle plays the role of “antagonist”.
What are antagonistic muscle pairs enlist them with relevant examples?
Antagonistic muscles are those muscles which produce movements in an antagonistic pair of muscles by opposing the movement of the agonistic muscle . i.e. when one contacts the other relaxes and vice versa. Example- biceps and triceps, quadriceps and hamstrings.
Which muscles are called antagonistic muscles?
Antagonistic Muscle is a muscle that opposes the action of another. For example, when the triceps oppose the contraction of the flexing biceps by relaxing, the triceps would be regarded as the antagonistic muscle to the biceps whereas the biceps, the agonist muscle.

Which type of muscle works together with the agonist?
An antagonist muscle works with an agonist muscle by stabilising the movement that the agonist is doing.
