Outcome Measures

Primary Outcomes (3)

  • Change from baseline muscle viscoelastic properties at immediately after exercise

    Muscle viscoelastic properties was assessed with Myoton® PRO device. It is an evidence-based device that evaluates the bio-mechanical properties of soft biological tissues in a non-invasive, objective, reliable, inexpensive, quick and easy manner. Myoton® PRO is used in studies to evaluate superficial skeletal muscles, connective tissues such as tendons and ligaments, and other soft tissues. It is a highly reliable method for assessing the tone, stiffness, elasticity of muscles.

    10 minutes

  • Change from baseline proprioception at immediately after exercise

    Proprioception was assessed with MarVAJED (Marmara Visual Auditory Joint Education Device). MarVAJED is a system for evaluating joint range of motion, analyzing joint position sense, offering biofeedback support to increase joint control, as well as directing it to controlled exercises. Analyzes joint movement with the help of small sensors. Transfers the obtained data to mobile phone, tablet or personal computer.

    10 minutes

  • Change from baseline static stretching exercise intensity at the beginning of each exercise

    A visual analog scale of 100 mm was used to assess the intensity of stretching exercise perceived by the participant at the beginning of each repetition. The visual analog scale is used to visually measure the intensity of the detected mechanical stimulus. 0 means "no stretch" and 100 means "maximum tolerable stretch without pain". Perceived violence from left to right increases.
