Biomechanical Parameters of Muscles, Objective Assessment Using MyotonPRO

Measurement of muscle parameters plays an inherent role in investigating top athletes. However, traditional measurement approaches are based on collected muscle parameters in the laboratory and are not applicable directly on the sports grounds. The paper presents measurement of muscle parameter using handheld and easy to use MyotonPRO device during physical exercise (demonstrating by squats) in the group of active sportsmen (10 male, 23.5±3.2 years) and in the group of non-sportive people (10 male, 25.1±5.4 years). Measured muscles were gluteus maximus, vastus medialis and vastus lateralis on both sides of the body. The t-test with significant level of 5% was used for statistical comparison. The parameter of mechanical stress relaxation time has been found as the most significant marker in this study. Changes occurred in the muscle gluteus maximus on both sides of body and in the vastus medialis muscle on the right side. All results are discussed.
