ℹ shoulder shrug --- 💪🏼 usually to strengthen the top of the trapeze is usually shrinking the shoulders holding a weight. --- 🤔 however, some authors have proposed that a variant of this exercise with a 30° shoulder abduction could increase muscle activation, so a study was carried out to corroborate this hypothesis. --- 📚 a team of Australian researchers compared the activation produced by two variants of shoulder shrinkage with dumbbells. --- 👉🏼 for this they brought together healthy people (11 women and 12 men) as well as patients with Multi-purpose glenohumeral instability. --- ✔ They all made both variants of the exercise, both with arms on the side (right) and with a shoulder abduction of 30° (left). --- 👉🏼 in each variant, the subjects performed 10 replays with concentric and eccentric phases of 2 seconds each and were allowed to have up to 30 seconds of rest between each repetition to avoid the effect of fatigue . --- ✔ the load used was close to 25 % of its maximum muscle contraction in a 90°, shoulder abduction so the "healthy" group used 2,5 kg dumbbells and the group with Complications in the shoulder of 2 KG. --- 💪🏼 under both conditions in each repetition, the emg activity of the high, medium and low parts of the trapeze was recorded next to that of the previous serrato muscle. --- ✔ the voluntary maximum isometric contractions for each muscle were also measured in 4 different positions. --- 👍🏼 the finding was that the variant with the 30° abduction had a significantly higher muscle activation in the high and low parts of the trapeze in all participants. --- ✔ the above may be because the abduction generates a change with respect to the traditional way of doing exercise (arms on the side) on the axis of contraction of muscle fibers, all of this facilitated by the external rotation of The Scapulae. --- ℹ we hope you serve this information and don't forget to tag someone who can serve you! --- #gymshark66 #gymsharkwomen #gym #gymtime#chestworkout #shoulders #triceps #gains #workout #work #workouttime #workoutmotivation #benchpress #workouts #fitness #fit #fitnessmotivation #respect #freestyle #musculations (en Gold's Gym) https://www.instagram.com/p/Bzs9f3FJXzd/?igshid=1lcmetzkkx7pw
