Brief summary: Stretching is the process of positioning certain muscles and related soft tissues of the body in a position that will lengthen them. In addition to increasing the range of motion of stretching, different stretching on many functional (maximum isometric torque, muscle-tendon stiffness, passive-resistive torque, viscoelastic deformation) or structural parameters (muscle stiffness, tendon stiffness, muscle fascicle length, pennation angle, neuromuscular relaxation) We can make changes using methods.

Static stretching usually involves actively or passively moving a limb to the full range of motion, holding this stretched position for 15-60 seconds, and then repeating it 2-4 times. Dynamic stretching encompasses all body movements and involves actively moving the active joints through the range of motion in a controlled manner. PNF stretching is known to be more effective than other stretching techniques as it increases both passive and active flexibility and improves joint range of motion in the short term.

The appropriate evaluation of muscle characteristics and keeping a regular record are very important for the course of rehabilitation, clinical decisions, the creation of an appropriate treatment plan, and the evaluation of treatment practices. Objective evaluation methods are needed to measure the functional state of the muscles, that is, their viscoelastic properties. Myotonometric measurement, which is a painless, objective, and non-invasive measurement method, allows the measurement of muscle tone, elasticity, and stiffness. The myotonometer device is a portable handheld device used to measure the stiffness of soft tissues, including muscles and tendons, using a non-invasive approach. It is a device that is easy to use, fast, and very suitable for the purpose. Based on this information, the aim of our study is to evaluate the effects of different stretching types on gastrocnemius muscle viscoelastic properties and performance.
