This research aims to examine the effects of different swimming styles (freestyle, breaststroke, butterfly, and backstroke) on the characteristics of the shoulder girdle muscles in young swimmers. Although it is known that shoulder girdle muscles undergo different levels of activation depending on swimming style, studies systematically examining these differences, especially in young swimmers during their developmental years, are limited. Identifying style-based differences in shoulder girdle muscle activation is of great importance for both optimizing training programs and preventing injuries.

| Measuring of the biomechanical properties of muscles with MyotonPro. | Other | MyotonPro is used to measure the biomechanical properties of muscle. During measurements, participants will be seated in a chair with back support; bilaterally Biomechanical properties (F - Natural Oscillation Frequency [Hz], characterizing Tone or Tension, S - Dynamic Stiffness [N/m], D - Logarithmic Decrement [relative unit], characterizing Elasticity, R - Mechanical Stress Relaxation Time [ms], C - Ratio of Relaxation and Deformation time [relative unit], characterizing Creep) of the anterior, middle and posterior parts of the deltoid muscle and the upper, middle and lower parts of the trapezius muscle were measured using Myoton PRO. All measurements will be compared statistically according to swimming styles. |
