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.
Shoulder
A dumbbell fly is an exercise move that is intended to work your arms and pecks. You lay down and move your arms from straight out to your sides to above your face.
Isometric
The quads
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.
Eccentric Flexors and Concentric Flexors
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.
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).
incline dumbbell press best chest exersize to do
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.
