Official title

The Influence of Shoulder Manipulation on Muscle Strength and Stiffness and Motor Functionality of Volleyball Players During Training

Overview

Currently, it is difficult to find studies in the literature assessing the influence of manual therapy on kinetic and kinematic factors for the upper limbs of volleyball players, which in the long run may translate into a reduction in injuries by improving strength and balance in athletes, when planning training or therapy.

Interventions

  • Other Manual Therapy
    This technique involves a low-amplitude, high-velocity push on the shoulder joints with an additional two-second tension
  • Other Placebo
    This technique involves a low-amplitude, high-velocity push on the shoulder joints with an additional two-second tension
  • Other Tape elastic
    The following intervention will be performed: application with an elastic band

Primary outcome measures

  • Assessment of MVC. [Time frame: The study will be conducted 3 times: pre-intervention, immediately after the intervention and immediately after training session. Each isometric muscle test lasts 3 seconds.]
  • Assessment of MVC. [Time frame: The study will be conducted 3 times: pre-intervention, immediately after the intervention and immediately after training session.Each isometric muscle test lasts 3 seconds.]
  • Muscle stiffness [Time frame: The study will be conducted 3 times: pre-intervention, immediately after the intervention and immediately after training session. Each Myoton application lasts 1 sec for one point.]
Secondary outcome measures (4)
  • Assessment of proprioception. [Time frame: The test will be performed 3 times: pre-intervention, immediately after the intervention and immediately after training session. Each joint measurement will be performed at three settings: 30, 45 and 90 degrees.]
  • Y balance test [Time frame: The test will be conducted 3 times: pre-intervention, immediately after the intervention and immediately after training session.]
  • Med Ball Throw [Time frame: The test will be conducted 3 times: pre-intervention, immediately after the intervention and immediately after training session.]
  • Close Kinetic Chain Upper Extremity Stability Test [Time frame: The test will be administered 3 times: pre-intervention, immediately after the intervention and immediately after training session.]
