简要总结
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.

结局指标
主要结局
Assessment of MVC.
时间窗: 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 EMG is an assessment of electrical characteristics during the test, which is measured by the repetition frequency of muscle motor unit discharges, which is measured in Hz, at the same time of the test.Time
Muscle stiffness
时间窗: 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.
Muscle stiffness - characteristic resistance to physical contraction, which deforms initially forming. Stiffness (N/m) was calculated as S = amax.mprobe/Δl.
Assessment of MVC.
时间窗: 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 EMG is an assessment of electrical characteristics during the test, the electrical source of which is the muscle membrane potential, and measured in μV.
次要结局
- Assessment of proprioception.(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(The test will be conducted 3 times: pre-intervention, immediately after the intervention and immediately after training session.)
- Med Ball Throw(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(The test will be administered 3 times: pre-intervention, immediately after the intervention and immediately after training session.)
