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.

Assessment of MVC.
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.
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.
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
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
Muscle stiffness - characteristic resistance to physical contraction, which deforms initially forming. Stiffness (N/m) was calculated as S = amax.mprobe/Δl.
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.
Assessment of proprioception.
Assessing proprioception is an assessment of the angular position of a joint and then an attempt to reproduce it, measured in degrees.
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
Consists of the volunteer standing on one leg while simultaneously stretching the other lower limb in 3 different directions. These are: anterior, posteromedial and posterolateral.

Time frame: The test will be conducted 3 times: pre-intervention, immediately after the intervention and immediately after training session.
Med Ball Throw
It involves the volunteer sitting on the floor with their legs apart and having to throw a 2 kg ball forward in front of them.
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
The volunteer assumes a push-up position with their hands 36 inches apart, and their performance is assessed based on how many times in 15 seconds the person can lift one arm
Time frame: The test will be administered 3 times: pre-intervention, immediately after the intervention and immediately after training session.
