Can shoulder muscle coordination during the support scale at ring height be replicated during training exercises in gymnastics?

The support scale at ring height, the swallow, is a difficult strength element, usually performed in gymnastics. Coaches try to simulate the swallow position during training to strengthen muscles, specifically in the position used for competition. However, the real effect of this position's simulation on muscle force and coordination and consequently on the muscle activity has not been determined.

Effects of two devices on the surface electromyography responses of eleven shoulder muscles during Azarian in gymnastics.

Difficult elements of strength such as Azarian must be presented on the rings. Specific-muscles training may be realized with 2 devices, the Herdos and the Belt, both of which reproduce the competitive situation and allow many repetitions. The purpose of this study was therefore to compare the shoulder muscle activity during the performance of Azarian with each device.
