Pectoralis Minor Shorthening and Swimming Performance

One factor that is effective in acceleration during swimming is the force of the arm pulling the water. While the pectoralis minor muscle pulls the crocoid process forward, it pulls its posterolateral corner down, which helps the latismus dorsi to make an extension movement and the lower trapezius to depress the scapula. When the pectoralis minor muscle is short, it prevents maximum reach in the arm because its full function cannot be revealed. It is thought that depression of the scapula will directly affect acceleration in swimming, as it increases the backward thrust of the arm.

In most cases, exercise practices also affect the person psychologically. In order to ignore the psychological effects of the exercises, they were made to perform exercises that were similar to pectoralis minor stretching exercises but did not activate the muscle

The Control Group was not given any exercise and they continued to do their own training.
