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.

Does a dislocation occur when a twisting action tears the ligaments at a joint?
No, a dislocation is when the bones at a joint are forced out of their normal position. A tearing of ligaments due to a twisting action is more likely to cause a sprain, which is damage to the ligaments that connect bones at a joint.
How does the movement of the elbow joint change during supination and pronation?
During supination, the elbow joint rotates outward, allowing the palm to face upward. During pronation, the elbow joint rotates inward, causing the palm to face downward.
The supraspinatus is named for its location on the posterior aspect of the scapula above the spine What is its action?
The supraspinatus muscle is responsible for initiating abduction of the arm at the shoulder joint. It also helps stabilize the shoulder joint during arm movements.
The main action of the flexor hallicus longus muscle are to?
The main action of the flexor hallucis longus muscle is to flex the big toe and help in plantar flexion of the ankle joint. It also contributes to support the arch of the foot and assists in propulsion during walking and running.
How does the range of motion in the shoulder joint change during flexion and extension movements?
During flexion, the shoulder joint allows the arm to move forward and upward, increasing the range of motion. During extension, the shoulder joint allows the arm to move backward and downward, decreasing the range of motion.
What is the concentric joint for reverse fly?
Shoulder
What is the concentric joint action in a lateral raise?
hamstring
What is the concentric joint action for lateral raise?
horizontal abduction
What is the concentric joint action of the hamstring curl?
flexion exstention
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 is the joint action during a shoulder press?
During a shoulder press, the primary joint actions are shoulder flexion and elbow extension. The shoulder joint allows for the movement of raising your arm overhead, while the elbow joint extends to push the weight up. Additionally, there is some scapular movement involved to stabilize the shoulder blades during the press.
When was National Joint Action Committee created?
National Joint Action Committee was created in 1969.
What is the action of the hamstrings in jogging?
The role of the hamstring muscle group during running is extending and hyperextending the hip joint
What are different types of contraction in sport?
The different types of contraction in sport is; Concentric Eccentric you also have to include; joint action e.g. Extension / flexion the agonist / agonistic muscle pairs e.g. hamstrings, quadriceps, biceps, triceps ect. & the joint itself e.g. knee, elbow, shoulder,
When was Joint Action Committee for Political Affairs created?
Joint Action Committee for Political Affairs was created in 1981.
