About this trial
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.
Eligibility criteria
This trial accepts healthy volunteersQualifiers
healthy individuals who are over 18 years old,
a player from the AZS volleyball league,
a player who regularly competes in the league,
expressing informed consent to participate in the study and undertaking to comply with the track regulations and wear a helmet.
Disqualifiers
lack of volunteer consent,
previous surgeries of the upper, lower limb and spine,
other upper limb injuries in the last 6 months,

Trial outcomes
Primary outcomes
1
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.2
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.3
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.Secondary outcomes
1
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.2
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.3
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.4
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 and move it across the position they are holding their hand in, and touch the other hand with it.
Time frame
The test will be administered 3 times: pre-intervention, immediately after the intervention and immediately after training session.Sponsors and contacts
