![]() ![]() According to a 2003 study in college-age women, one third of participants were able to complete a pull-up after a twelve-week full-body strength training program. Some organizations allow women to use a flexed arm hang as a substitute for a pull up in fitness tests after discovering that few women could complete a pull-up. There is a traditional belief that women are unable to complete a pull-up. They are also used by police and military to increase muscular strength among their members. Pull-ups are used as a conditioning activity for many sports, especially those that require pulling strength, including rock climbing, gymnastics, rope climbing, rowing, and swimming. The strength to do a pull-up is correlated with job-related tasks in some careers such as firefighting, police, and military. Pull-ups are a common way to measure upper body strength, endurance, and strength to weight ratio. ģ1st Marine Expeditionary Unit members in a team pull-up competition. This can be used as a progression to performing a standard pull-up. īeginning from the top position of the pull-up, the participant gradually lowers herself into the dead hang position. Assisted pull-ups can be used to increase pulling strength among those who cannot do an unassisted pull-up. The effective weight of the participant is reduced by such means as resistance band, counterweight, or resting the feet on a surface to make the exercise easier. Originating in gymnastics, it is also popular in CrossFit where it may be performed with kipping. Ī pull-up that transitions to a dip it is more difficult than a pull-up and requires significant strength and technique to execute. Kipping pull-ups are considered high risk for injury and are a major cause of shoulder injury in CrossFit athletes. Kipping pull-ups have lower muscle activation in the upper body but greater activation in the lower body and core it is possible to perform them faster and complete more repetitions before encountering upper-body fatigue. Īn easier version in which momentum is built by swinging the legs. ![]() Ī one arm pull-up is performed by using only one arm to lift the body another variation is using only one finger. To increase the difficulty, weights are added using a dip belt, weight vest, or other means. The end range of motion at the top end may be chin over bar or higher, such as chest to bar. Exampleīeginning by hanging from the bar, the body is pulled up, and finished by lowering the body until arms and shoulders are fully extended. A grip that is too wide could increase the injury risk or reduce the number of repetitions able to be completed due to lengthening the lever arm. A pull-up may be completed using different widths of hand position studies have found that participants freely choose a grip that is between 20 and 50 percent wider than shoulder width. The 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 kinematically 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 multiple joints. ![]()
