Hello forum. It's always interesting to read something about gymnastics. Even though I'm not even close to the level. and I thought you might be interested in this analysis. thanks you all.
An analysis of mobilization pattern in agonist muscles during the Maltese cross and Iron cross position in rings.
This study accessed male gymnasts with more than eight years of experience who were capable of performing Iron Cross and Maltese Cross holds on rings to analyze the amount of agonist muscle mobilized and myoelectrical activities of trapezius muscle, deltoid muscle, latissimus muscle, and musculus pectoralis major on the upper body and flexor carpi radialis, brachioradialis, triceps brachii muscle, and biceps brachii muscle in the upper limb. The results were presented as follows.
1) The amount of agonist muscle mobilized
(1) While performing Maltese Cross hold, the upper body muscle mobilized the most between 2-4seconds was musculus pectoralis major, followed by latissimus muscle, deltoid muscle, and trapezius muscle. In Iron Cross hold, trapezius muscle ranked first, followed by musculus pectoralis major, deltoid muscle, and latissimus muscle. Trapezius muscle and deltoid muscle were mobilized more in Iron Cross hold while latissimus muscle and musculus pectoralis major were mobilized more in Iron Cross hold.
The the upper limb muscle mobilized the most while performing Maltese Cross hold was brachioradialis, followed by triceps brachii muscle, flexor carpi radialis, and biceps brachii muscle. In the meantime in Iron Cross hold, biceps brachii muscle took first place, followed by brachioradialis, triceps brachii muscle, and flexor carpi radialis. While brachioradialis, biceps brachii muscle, and triceps brachii muscle were mobilized more in Maltese Cross hold, flexor carpi radialis was mobilized more in Iron Cross hold,
(2) While performing Maltese Cross hold, the upper body muscle mobilized the most between 4-6seconds was musculus pectoralis major, followed by trapezius muscle, latissimus muscl, and deltoid muscle. As for Iron Cross hold, deltoid muscle took first place, followed by trapezius muscle, latissimus muscle, and musculus pectoralis major. Trapezius muscle, deltoid muscle, and latissimus muscle were mobilized more in Iron Cross hold, while musculus pectoralis major was mobilized more in Maltese Cross hold.
The upper limb muscle mobilized the most in Maltese Cross hold was flexor carpi radialis, followed by brachioradialis, triceps brachii muscle, and biceps brachii muscle. In Iron Cross hold, flexor carpi radialis was mobilized the most, followed by triceps brachii muscle, brachioradialis, and biceps brachii muscle. Brachioradialis and triceps brachii muscle were mobilized more in Iron Cross hold while flexor carpi radialis was mobilized more in Maltese Cross hold. In the meantime, biceps brachii muscle did not display any difference between Maltese Cross and Iron Cross holds.
2) The myoelectrical activity of agonist muscle
(1) While performing Maltese Cross hold, the upper body muscle whose myoelectrical activity was the highest between 2-4 seconds was deltoid muscle, followed by trapezius muscle, latissimus muscle and musculus pectoralis major. In Iron Cross hold, latissimus muscle generated the highest myoelectrical activity, followed by musculus pectoralis major, deltoid muscle, and trapezius muscle. Trapezius muscle and deltoid muscle generated higher myoelectrical activity in Maltese Cross hold, while latissimus muscle and musculus pectoralis major produced higher myoelectrical activity in Iron Cross hold.
Of the upper limb muscles, flexor carpi radialis, generated the highest myoelectrical activity in both Maltese Cross hold and Iron Cross hold, followed by biceps brachii muscle, brachioradialis, and triceps brachii muscle. Flexor carpi radialis, brachioradialis, biceps brachii muscle, and triceps brachii muscle produced higher myoelectrical activity in Iron Cross hold than in Maltese Cross hold.
(2) The upper body muscle whose myoelectrical activity was the highest between 4-6 seconds in Maltese Cross hold was latissimus muscle, followed by deltoid muscle, musculus pectoralis major, and trapezius muscle. In Iron Cross hold, latissimus muscle took first place. followed by musculus pectoralis major, deltoid muscle, and trapezius muscle. Trapezius muscle, deltoid muscle, and musculus pectoralis major generated higher myoelectrical activity in Maltese Cross hold, while latissimus muscle produced higher myoelectrical activity in Iron Cross hold.
In the meantime, the upper limb muscles whose myoelectrical activity was the highest in Maltese Cross hold was biceps brachii muscle, followed by triceps brachii muscle, brachioradialis, and flexor carpi radialis. In Iron Cross hold, triceps brachii muscle topped, followed by biceps brachii muscle, flexor carpi radialis, and brachioradialis. Flexor carpi radialis, brachioradialis, biceps brachii muscle, and triceps brachii muscle generated higher myoelectrical activity in Maltese Cross hold than in Iron Cross hold.
In conclusion, the analysis of agonist muscles mobilized during each movement, found that gymnasts need to do training that strengthens musculus pectoralis major, trapezius muscle, latissimus muscle, and flexor carpi radialis. If they want to perform Iron Cross hold smoothly, they should strengthen deltoid muscle, trapezius muscle, latissimus muscle, and flexor carpi radialis through training.
