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.

That's why it's important to develop them. Likewise, muscle strength should be increased in order to maintain movement performance and prevent injuries. Performance is the evaluation of how much the psychological, physiological and biomechanical requirements required for a sportive activity are provided. Individual and team sports, by their very nature, result in winning and losing. In this respect, it is important that the performance is at the highest level. In addition to strength, speed is also an important parameter in performance. With the programs made by combining these parameters, sportive performance and athletic success can be increased. The ability to effectively perform parameters such as throwing, throwing and hitting the ball in overhead sports affects performance results. Athletes competing in branches where overhead movements requiring high muscle activity are used intensively; In addition to strength and flexibility, which are key components of performance, sensorimotor accuracy is also of great importance.
Fascia; It is a body network that is the continuation of the connective tissue and is shaped by stretching, and it surrounds all organs and body structures. If the fascial tissue can be trained at the appropriate level (appropriate level of flexibility and elasticity), it can be beneficial in terms of protection from injuries as well as increasing sports performance. When we look at the literature, we see that the importance of this issue has increased in recent years. Myofascial release is an up-to-date method that appears to be effective in improving joint and fascia mobility, increasing body awareness, and aiding muscle reduction. Myofascial release application has become popular around the world in recent years, and it shows itself as one of the exercise trends of athletes.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.
With the myofascial release application that we plan to do, we aim to improve these parameters and thus provide the athletes with an alternative application method in terms of preventing injuries and improving performance. When we review the literature, we are the first study to examine the effectiveness of myofascial release in the upper extremity and the long-term effects on athletes doing overhead activities.
For all these reasons, the aim of this study is; To examine the effect of 8-week myofascial release application to the shoulder and elbow region on mobility, muscle strength, joint position sense, force matching, performance and well-being, and to examine the effect of the application at the 4th week, 8th week (end of the application), and 6th month after the first evaluation. is to detect whether there is a change in these parameters. In this study, the effect of myofascial release on shoulder and elbow joints in overhead volleyball players will be investigated for the first time. We think that our study will shed light on the studies to be done in healthy and symptomatic individuals who are interested in sports where the upper extremity is at the forefront.

| Myofascial Release Techniques | Other | Volleyball players will perform these practices with a physiotherapist 3 days a week for 8 weeks (24 sessions), and their routine sports training will continue. Participants in the group will be shown how to use rolling materials. The application will be performed as 2 sets in a session using the body weight of the person, as 10 rolls in 1 minute. The application time will be 2 minutes in total for each session. There will be 30 seconds of rest between sets. The participation rate limit for the sessions was determined as 80%. The application rate will be controlled with a metronome. The pressure to be created using body weight will be controlled by a numerical pain scale. The technique will be applied to the biceps brachii, latissimuss dorsi, upper trapezius, pectoralis minor, pectoralis major, and thoracic extensor muscles. During the application, a foam roller and a rolling stick (Thera-Band, Hygienic Corporation, Akron, OH) will be used. |
| Measure | Description | Time Frame |
|---|---|---|
| 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 |

In this application; with the help of the palm of the hand, pressure will be applied to the surface of the relevant muscles, first without pressure for 1 minute, then after resting for 30 seconds. The given pressure will be 2 out of 10 (0: No pain/discomfort due to pressure, 10: Unbearable pain/discomfort due to pressure). This group will also be given the right to receive a myofascial relaxation program which the experimental group received, after the study period ended. |
