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 is the eccentric joint action for lateral raise?
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 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.
Which phase of the joint air estimate process is involves wargaming each COA?
The phase of the joint air estimate process that involves wargaming each course of action (COA) is the Analysis and Wargaming Phase. This phase focuses on analyzing the potential COAs and conducting wargames to simulate possible outcomes and determine the most effective course of action for the joint air operation.
What joint do you use during a bicep curl up phase?
During the up phase of a bicep curl, the primary joint used is the elbow joint. As you lift the weight, the biceps brachii muscle contracts and causes flexion at the elbow, allowing the forearm to move closer to the upper arm. This action primarily targets the biceps while also engaging the forearm muscles.
What does cellular activity do during the phases of Eccentric contraction?
During the eccentric contraction phase, cellular activity involves lengthening the muscle fibers while generating force. This phase creates tension in the muscle as it elongates, allowing for controlled movement and resistance against external forces. Additionally, cellular processes such as protein breakdown and remodeling contribute to muscle adaptation and strength gains.
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 eccentric joint action for lateral raise?
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.

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 is the joint action during the eccentric phase of a biceps curl?
A concentric movement would be flexing the elbow and curling a dumbbell towards the shoulder, an eccentric contraction would be the opposite movement ie bringing the dumbbell back down towards the thigh.
When performing push ups the concentric phase is?
when you push yourself away from the floor, the lowering phase is the eccentric phase concentric = shortening of muscles - i like to think of this as when the muscles are "working" eccentric = lengthening of muscles - i like to think of this as when the opposite muscles would work to perform the action - e.g. when biceps brachii is eccentric in a bicep curl it is on the lowering phase (i.e. elbow extension - usually performed by triceps brachii)
Which phase of the joint air estimate process is involves wargaming each COA?
The phase of the joint air estimate process that involves wargaming each course of action (COA) is the Analysis and Wargaming Phase. This phase focuses on analyzing the potential COAs and conducting wargames to simulate possible outcomes and determine the most effective course of action for the joint air operation.
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.
What action best represents an eccentric contraction?
An eccentric contraction occurs when a muscle lengthens while under tension. A prime example is the lowering phase of a bicep curl, where the biceps elongate as you slowly lower the weight back down. This action requires control and is essential for activities that involve deceleration or controlled movement.
What phase is the muscle the strongest eccentric concentric or isometric?
Isometric
Is a squat eccentric or concentric?
Both. Concentric: Exercise where the muscle is contracted under a load Eccentric: Exercise where the muscle is stretched under a load. So when you squat down its eccentric, when you come back up its concentric. Most exercises are both, with a few exceptions (i.e. jumping of a wall is mainly eccentric, while a punch is mainly concentric. Eccentric contraction is associated with increased muscle growth, but also DOMS (Delayed onset muscle soreness, when your muscles are very sore after a workout).
What is the correct phase order of the stretch shortening cycle?
The correct phase order of the stretch-shortening cycle is eccentric contraction, amortization phase, and concentric contraction. This sequence allows for energy storage during the eccentric phase, a brief pause to transition from lengthening to shortening, and then rapid muscle shortening in the concentric phase for powerful movement.
What are some effective eccentric hip exercises that can help improve hip strength and stability?
Some effective eccentric hip exercises to improve hip strength and stability include single-leg squats, lateral band walks, hip bridges, and Romanian deadlifts. These exercises focus on controlling the lowering phase of the movement, which can help strengthen the hip muscles and improve stability.
