3/2/2023 0 Comments Wide pull ups muscles involvedThe pull-up performed with an supinated grip is sometimes called a chin-up. Pull-ups can be done with a supinated, neutral, or pronated grip devices allow the grip to rotate during the pull-up. According to one study, the pronated grip pull-up with hands at shoulder width apart led to less risk of impingement than other variations studied. Overhead movements such as pull-ups reduce the subacrominal space and create a risk of shoulder impingement. Muscle activation is significantly different depending on whether the pull-up is completed individually or in a set without resting between repetitions, which is more efficient due to muscle and tendon strech-shortening rebound. Ī 2017 study found that pronated grip activated the middle trapezius more than the neutral grip, but that overall the muscle activation of different grip variants was similar. There is similarity to the pull-down in terms of the muscle activation. The trapezius, infraspinatus, and brachialis muscles are most active at the beginning of the pull-up the latissimus dorsi, teres major, and biceps brachii reach peak activity during the middle of the movement, and the triceps brachii and subscapularis experienced maximum activity at the top of the movement. Pull-ups are a closed-chain, compound movement involving flexion at the elbow and adduction or extension of the shoulder joint. The end range of motion at the top end may be chin over bar or higher, such as chest to bar. From the top position, the participant lowers their body until the arms and shoulders are fully extended. Beginning by hanging from the bar, the body is pulled up vertically.
