Others
Basic objectives -Others
The detailed objective of this study is to clarify the baseline cross-sectional characteristics of joint function, movement patterns, performance indicators, and questionnaire-based assessments, and to examine whether these variables are associated with the occurrence of volleyball-related musculoskeletal injuries and the injury reporting rate during the prospective follow-up period, in order to explore factors useful for injury prevention.

Key inclusion criteria
Players who belong to a high school volleyball team and regularly participate in volleyball activities; are able to undergo the baseline assessment and cooperate with injury surveillance during the follow-up period; and provide written informed consent, with additional written consent from a legal guardian for minors.
Key exclusion criteria
Participants meeting any of the following criteria will be excluded:
- Players who have an acute injury or severe musculoskeletal condition at baseline that restricts participation in volleyball.
- Players with a history of surgery involving the upper extremity, trunk, or lower extremity, or with neurological disorders or other conditions that may affect the assessment of joint function, movement, or performance, as judged by the principal investigator.
- Players who are unable to complete the baseline assessment.
- Players who are considered unlikely to cooperate with injury surveillance during the follow-up period.
- Players from whom written informed consent cannot be obtained from the participant or, for minors, from a legal guardian.
