The eccentric joint action during a lateral raise occurs when the deltoid muscles lengthen while controlling the descent of the weights after reaching the peak height of the lift. As you lower the weights back to the starting position, the muscles are under tension, which helps to promote strength and muscle growth. This phase is crucial for muscle development, as it emphasizes control and stability throughout the motion. Overall, the eccentric action aids in preventing injury and improving overall muscle function.

What is the joint action in the eccentric phase lateral raise?
In the eccentric phase of a lateral raise, the primary joint action occurs at the shoulder joint, specifically involving shoulder abduction. During this phase, the deltoid muscles, particularly the middle deltoid, control the lowering of the arms back to the starting position. The eccentric contraction helps to maintain tension in the muscles while they lengthen, promoting stability and muscle growth. Additionally, the scapulae may also move slightly to assist in the controlled descent of the arms.
What joint actions occurring in a lateral raise during the concentric and eccentric phase?
To see eccentric contraction, look at the biceps curl with flexion around the elbow. As you lower a weight, you are working against resistance, letting the joint angle increase to lower that object under your control.The opposite is the concentric contraction were the arm is flexed upward to decrease the angle at the elbow.
What role does the suprespinatus play in a lateral raise?
The supraspinatus muscle is one of the key muscles involved in a lateral raise. It is responsible for initiating the movement by abducting the arm away from the body. It works in conjunction with other shoulder muscles to raise the arm to the side.
Do the tendons work with others to raise and lower the forearm?
Yes, tendons work in conjunction with muscles to raise and lower the forearm. When a muscle contracts, it pulls on the tendon, which then exerts force on the bone to facilitate movement at the joint. For example, the biceps brachii tendon helps raise the forearm, while the triceps brachii tendon assists in lowering it. This coordinated action allows for smooth and controlled movements of the forearm.
What is the action of the levator scapulae?
The levator scapulae muscle primarily elevates and rotates the scapula (shoulder blade) downward and inward, allowing for movements such as shrugging the shoulders. It can also contribute to lateral flexion of the neck when acting unilaterally.
What is the eccentric joint action for a lateral raise?
In a lateral raise, the eccentric joint action occurs when the arm is lowered back down after reaching the peak of the lift. During this phase, the deltoid muscles lengthen while controlling the descent of the weights, which helps to maintain tension and stability. This eccentric action is crucial for muscle development and injury prevention, as it promotes controlled movement and strength throughout the full range of motion.
What is the joint action in the eccentric phase lateral raise?
In the eccentric phase of a lateral raise, the primary joint action occurs at the shoulder joint, specifically involving shoulder abduction. During this phase, the deltoid muscles, particularly the middle deltoid, control the lowering of the arms back to the starting position. The eccentric contraction helps to maintain tension in the muscles while they lengthen, promoting stability and muscle growth.
