Athletes Clinical Trial
Official title:
Investigation of the Effects of Myofascial Release Techniques on Shoulder-Elbow Mobility, Sensorimotor Function and Performance in Volleyball Players
Sports that require overhead activities (volleyball, tennis, basketball) include components such as rapid displacement, strength and movement control.Volleyball is also called as an overhead sport in terms of the way it is played. In the realization of these sports; Sub-parameters such as proprioceptive sense, strength, throwing rate, flexibility play a role. During these activities, the shoulder and elbow joints are overloaded. To meet this load, the joint must provide the necessary mobility and stability. Proprioceptive sense in increasing the quality and width of movement as well as providing dynamic joint stability in overhead sports; Increasing the range of motion of the joint, reducing muscle stiffness and thus increasing flexibility are effective in providing mobility. That's why it's important to develop them. Likewise, muscle strength should be increased in order to maintain movement performance and prevent injuries. The use of myofascial release techniques as an exercise method has increased in recent years. Application; The effects on parameters such as strength, performance and flexibility were investigated. Studies have focused more on the lower extremities and acute effects. There is no study on the subject examining proprioceptive sensation in volleyball players in the upper extremity. Therefore, our aim is to examine the chronic effects of the application on shoulder and elbow joint mobility, sensorimotor function and performance.

---|---|---|---|---|
Primary | Proprioception (elbow and shoulder) | Change of biceps brachii and shoulder internal rotation joint position sense (with digital inclinometer in degree) (Target angel:Elbow:45 degree, shoulder:45 degree). The target angles to be tested will be taught by the investigators with eyes open 3 times and eyes closed 3 times. The participant will then be asked to bring it to the target angle with their eyes closed. The deviation value from the target angle will be recorded. | Baseline, after 4 and 8 weeks myofascial release techniques period and then follow up measurement 6. month | |
Primary | Muscle Strength (elbow and shoulder) | Change of biceps brachii and shoulder internal rotation isometric strength (in kg, with hand held dynamometer).The average of three consecutive repetitions will be recorded. | Baseline, after 4 and 8 weeks myofascial release techniques period and then follow up measurement 6. month. | |
Primary | Mobility (shoulder) | Change of shoulder mobility (shoulder (internal and external rotation) range of motion, Back Scratch test:The distance between the middle fingers will be recorded in cm.). Measurements will be made 3 times, the average of the measured values will be recorded. | Baseline, after 4 and 8 weeks myofascial release techniques period and then follow up measurement 6. month. | |
Primary | Performance (Speed) | Change of shoulder and elbow performance (Dunk speed test with sportive radar). The tests will be conducted by measuring the maximum slam speed using a volleyball. The ball is thrown from a height of 2 to 3 meters by the coach. Participants dunk the ball into the net without touching the net and without occupying the opponent's court. Participants will be asked to practice 3 spikes at their maximum strength. The average of the three values will be taken. (km/h) | Baseline, after 4 and 8 weeks myofascial release techniques period and then follow up measurement 6. month. | |
Secondary | Well-Being | Change of participants well-being (Likert type well-being test) (Minimum:7 points, maximum: 35 points). The well-being of the participants will be evaluated with a 7-item questionnaire (fatigue, stress, sleep, muscle pain, enjoyment of training/exercise training, irritability and health). Scoring on a 5-point Likert scale will be required for each item. A total score between 7 and 35 will be calculated. | Baseline, after 4 and 8 weeks myofascial release techniques period and then follow up measurement 6. month. | |
Secondary | Performance | Change of shoulder and elbow performance (closed kinetic chain upper extremity stability test). Participants will be in a push-up position, the distance between the two hands will be adjusted to be 90 cm, then the number of repetitions completed within 15 seconds will be recorded by extending one hand towards the other hand. The test will be repeated 3 times and the average will be taken. | Baseline, after 4 and 8 weeks myofascial release techniques period and then follow up measurement 6. month. | |
Secondary | Mobility | Change of elbow (flexion-extension) range of motion, upper trapezius muscle length (With the test, muscle length will be recorded as short or normal) and pectoralis minor muscle length (For the pectoralis minor muscle, the length of the muscle, the distance from the junction of the sternum with the fourth rib (caudal edge) to the corocoid process, will be measured with a tape measure when the participant is standing and the upper extremity is in a free position. Three measurements will be made and the average of these measurements will be recorded in cm) | Baseline, after 4 and 8 weeks myofascial release techniques period and then follow up measurement 6. month. | |
Secondary | Muscle Strength | Change of triceps brachii and shoulder external rotation isometric strength (in kg, with hand held dynamometer). The average of three consecutive repetitions will be recorded. | Baseline, after 4 and 8 weeks myofascial release techniques period and then follow up measurement 6. month. | |
Secondary | Proprioception (joint position sense and force match) | Change of shoulder external rotation and abduction joint position sense (with digital inclinometer in degree) (External rotation:45 degree, abduction:100 degree) and force match ( hand held dynamometer ) (elbow and shoulder; internal, external rotation and abduction %50 of maximum voluntary contraction) (Force match: Three maximum voluntary isometric contraction trials will be performed at the desired angles and the highest value of the three trials will be used to determine the target force. 50% of the determined value will be calculated and the participant will be asked to repeat this calculated value.) (Joint position sense: The target angles to be tested will be taught by the investigators with eyes open 3 times and eyes closed 3 times. The participants will then be asked to bring it to the target angle with their eyes closed. The deviation value from the target angle will be recorded.) The average of the three measurements will be taken. | Baseline, after 4 and 8 weeks myofascial release techniques period and then follow up measurement 6. month. |
