  The present work proposes a biomechanics and performance analysis of an electromyography (EMG) signal during the squat exercise. More specifically the tests were made considering different angles of knee flexion, 90° and 130°. The results showed considerable differences between right and left side when power and muscular performance were compared. This result leads us to believe that weight training is not enough to achieve muscle balance. It is suggested that to improve results and performance on both sides a neurological adaptation is necessary. In addition, it was possible to determine with precision the moment when the muscle fibers are more recruited during the execution of the squat in both angles. .. View More»
