Abstract

Objective: Making changes and variations in training components compared to repetitive training can lead to better learning of the movement based on the principles of system self-organization. The present study aimed at investigation of the effect of differential and traditional trainings on electromyographic changes of upper torso muscles in performing and learning swimming breaststroke.

Methodology: In this study, 36 swimmers aged 20 to 25 years who had no history of swimming training were selected as a sample and randomly divided into control, traditional exercises and differential exercises groups. They learned swimming breaststroke in traditional and different trainings. Before and after 12 training sessions, the muscle activity level was measured based on the root mean square and mean time of activity of Pectoralis major, Latissimus dorsi, biceps and triceps muscles of swimmers using electromyographic signal.
