What extension of the lower arm is a result of the contraction of?
The extension of the lower arm is a result of the contraction of the triceps muscle, which is located on the back of the upper arm. When the triceps contracts, it straightens the arm by extending the elbow joint.
Examples of different types of muscular contraction relating to four types of physical activity?
=1. Throwing a ball in a football match - this would be a concentric contraction because when bringing the ball behind the head your biceps do the concentric contraction. This is because the two ends of the bicep come closer to each other when doing the action. == ==2. pomallhorses in gymnastic - this is a isometric contraction because the biceps and triceps when doing this the ends of the muscle do not come closer of get further away form each other they stay the same. == ==3. Kicking a ball in rugby - this is an concentric contraction because the ends of the hamstring get further away when doing this action therefore it is a concentric contractions.== ==4. Sit ups - when doing sit ups your abdominals get closer when you sit up form the floor there for this is a concentric contraction.=
Why Is the coactivation of the triceps necessary for proper functioning of the biceps and vice versa?
The coactivation of the triceps helps stabilize the elbow joint to prevent excessive movement during biceps contraction. This coactivation ensures efficient force production and coordination between the two muscle groups, leading to optimal performance and reduced risk of injury during various arm movements.
Which muscle does NOT flex the elbow?
The triceps brachii muscle does not flex the elbow; it is responsible for extending the elbow joint when it contracts.
What is the job for the triceps?
It's usually used when you push or lift an object. According to the movement of the arm, when you are exercising or working, you may use the biceps, the triceps, or both.
What extension of the lower arm is a result of the contraction of?
The extension of the lower arm is a result of the contraction of the triceps muscle, which is located on the back of the upper arm. When the triceps contracts, it straightens the arm by extending the elbow joint.
What happens to the bicep when your tricep contracts?
When the biceps contracts the triceps relaxes slowly. It happens when your arm is bent.
How do muscles bring about movement in an organism?
Contraction of the biceps and the relaxation of the triceps bend the arm .In straightening the arm the triceps contract and the biceps relax
What muscle is inhibited when the biceps brachii is contracted?
When the biceps brachii is contracted, the antagonist muscle that is inhibited is the triceps brachii. The biceps brachii is responsible for flexing the elbow, while the triceps brachii functions to extend the elbow. During this contraction, the activity of the triceps is reduced to allow for smooth movement and effective flexion at the elbow joint. This interplay between agonist and antagonist muscles is essential for coordinated movement.
What would the fixator be when the tricep is contracting?
When the triceps muscle contracts, the fixator is typically the muscles that stabilize the shoulder joint, such as the rotator cuff muscles. These muscles help maintain the position of the shoulder while the triceps extend the elbow. This stabilization allows for efficient movement and prevents unwanted motion during the contraction of the triceps.
Is it true that performing triceps stretch helps to increase the flexibility in the arm?
Yes. That is true.
Term for the triceps brachii during elbow flexion?
Triceps brachiiElbow flexion is due to the contraction of the biceps brachii, the prime mover. The triceps brachii extends as the biceps brachii contracts and therefore is the antagonist muscle.
How can I effectively train the long head of my triceps?
To effectively train the long head of your triceps, focus on exercises that target this specific muscle, such as overhead triceps extensions, skull crushers, and triceps kickbacks. Use proper form, gradually increase weight and reps, and ensure adequate rest for muscle recovery.
Does the triceps contract concentrically during the down phase of a push up?
No, the triceps do not contract concentrically during the down phase of a push-up. Instead, they are involved in an eccentric contraction as the elbows flex and the body lowers toward the ground. This eccentric action helps control the descent and stabilize the movement. During the upward phase, the triceps contract concentrically to extend the elbows.
Which of these muscles is formed form three divisions?
triceps

What is the muscle on the back of the upper arm called?
I think you are referring to the triceps. This is the muscle that attaches at the elbow and the shoulder. The one that you use when extending your arm. biceps; up triceps; under
