Observational model: CASE_CONTROL
Time perspective: CROSS_SECTIONAL
Sampling method: NON_PROBABILITY_SAMPLE
Study population: The population of the research consists of elite athletes and the sample of the research consists of elite volleyball players who volunteered to participate in the research. In our research, there is only one research group consisting of elite volleyball players and there are at least 28 volleyball players.

Brief summary: The aim of this study is to examine the relationship between injury risk and pain, fatigue, muscle strength, balance and quality of life in volleyball players. In this context, it will be investigated how the pain and fatigue levels experienced by volleyball players interact with muscle strength and balance and how these factors increase the risk of injury.

Detailed description: Musculoskeletal injuries are highly prevalent among volleyball players and this may be due to the interaction of various physical and subjective factors. Although some risk factors such as muscle strength and balance have been previously investigated, there is limited data on how these parameters together relate to injury risk and athlete health. In this cross-sectional study, standardized tests and self-report questionnaires will be administered to a sample of competitive volleyball players.
