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.
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.
