During the concentric phase of a sit-up, the primary joint action involves flexion at the hip and lumbar spine. The rectus abdominis muscle contracts to lift the torso towards the thighs, while the hip flexors assist in bringing the pelvis closer to the ribcage. This coordinated movement effectively engages the core muscles, facilitating the upward motion of the body.

What is the joint action during the concentric phase of reverse fly?
During the concentric phase of a reverse fly exercise, the shoulder joint primarily goes through horizontal abduction as the arms move outward away from the body. The scapulothoracic joint also engages to stabilize the shoulder blades and maintain proper alignment. This coordinated action involves the posterior deltoid and other muscles of the upper back to perform the movement efficiently and effectively.
During the concentric phase of the triceps bench dip is the shoulder joint experiencing flexion or extension?
Flexion
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.
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 muscle contraction occurs in the biceps brachii during the upward phase of the bicep curl?
a concentric contraction- a concentric contraction involves the muscle length, shortening during a contraction! YA-trick-YA!
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.
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 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.
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)
What muscles are eccentric and concentric when doing incline bench press?
The bench press has two phases: eccentric and concentric. The first phase, as you lower weight toward your chest, is called the eccentric, or muscle-lengthening motion. The second phase, as you raise the weight back up, is called the concentric, or muscle-shortening phase. It is during the concentric phase that you can feel your chest getting tight. Learning which muscles are used during the concentric phase of the bench press is beneficial for focusing your mind on the correct area and therefore improving your exercise technique.The primary concentric mover of the bench press is the pectoralis major, which you may better know as the chest. Depending on which version of the bench press you are doing, you will be recruiting a specific part of the muscle group. The regular bench press on a flat surface mainly works your middle pecs. The incline and decline versions mainly work your upper and lower pecs, respectively.
What phase is the muscle the strongest eccentric concentric or isometric?
Isometric
