An observational study in Young People, sponsored by Istanbul Gelisim University. Active, not recruiting at 1 site in Turkey (Türkiye). Open to participants aged 12 Years to 18 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-03-27.
Sponsored by Istanbul Gelisim University · Observational
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.
Istanbul Gelisim University is the lead sponsor of 59 studies on the registry; 7 are open to participants now.

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.
The measuring tape will be used to measure the swimmers' Right and left arms length (cm) and Arm span (cm). All measurements will be compared statistically according to swimming styles.
Passive range of motion of the upper extremity shoulder joint (flexion, extension, adduction, abduction, external rotation, and internal rotation) will be measured using a digital goniometer. Results will be recorded in degrees (°). All measurements will be compared statistically according to swimming styles.
