Intervention model description: Professional male athletes (basketballers, voleyballers, runners) will participate and divided to groups. AT, PF and ITB mechanical properties will evaluate with MyotonPro device (Myoton Ltd, Estonia). Ankle mobility will measure with inclinometer during a knee to wall lunge test.
Primary purpose: DIAGNOSTIC

Brief summary: The myotonometric assessment is becoming popular and important in athletic population. It is mentioned an alternate method than expensive methods, and it is easy and reliable assessment. Still there is not enough information of mechanical characteristics in athletic population and ankle mobility. Most clinicians or trainers can use this results and technique for enhancing performance, rehabilitation or prevention

Detailed description: The soft tissue mechanical properties can be assessed through elastography and ultrasonography. Both methods can measure passive and active soft tissue properties. These methods are the gold standard to measure stiffness and elasticity, but they are expensive, operator dependent and need a laboratory settings.Recently, myotonometric device has been used to measure the mechanical properties of the muscles and tendons. This method serves many advantages, such as non-invasive, painless and cost-effective. There is an increasing literature on athletic training about how training effects viscoelastic properties. However, to the best of our knowledge, there were no studies assessing stiffness and elasticity of AT, PF and ITB and the relation with ankle mobility in different sport disciplines. The purpose of this study were to demonstrate the mechanical properties of AT, PF and ITB and find out relation with restricted ankle mobility in athletes.
