Official title
Effects of the FIFA 11+ Exercise Program on Injury Incidence, Fear of Reinjury, and Physical Performance in Young Female Volleyball Players
Overview
This study aims to investigate the effects of an 8-week FIFA 11+ exercise program on wellness, rating of perceived exertion (RPE), dynamic balance, and single-leg functional performance in young female volleyball players, as well as to examine the relationships among these variables. The study will also evaluate the program's effects on injury incidence and fear of reinjury. The study is original in applying the FIFA 11+, a well-established injury prevention program, to volleyball and evaluating its effects together with training-load parameters through a multidimensional approach. It is expected to contribute to the literature by proposing a comprehensive model for monitoring athletic performance and injury risk in young female volleyball players.
Interventions
- Other FIFA 11
Participants will undergo an 8-week non-intervention control period followed by a 2-week washout period and an 8-week FIFA 11+ exercise program in addition to regular volleyball training. The program consists of structured running, strength, balance, plyometric, and agility exercises. Wellness, rating of perceived exertion, dynamic balance, single-leg functional performance, injury incidence, and fear of reinjury will be assessed before and after the relevant study periods.
Primary outcome measures
- Injury Incidence [Time frame: During the 8-week pre-intervention control period and the 8-week FIFA 11+ intervention period]
- Re-Injury Anxiety Inventory Scores [Time frame: At the end of the 8-week pre-intervention control period and immediately after the 8-week FIFA 11+ intervention]
- Daily Wellness Score [Time frame: Daily throughout the 8-week pre-intervention control period and the 8-week FIFA 11+ intervention period]
- Single-Leg Hop for Distance Test [Time frame: At the end of the 8-week pre-intervention control period and immediately after the 8-week FIFA 11+ intervention]
- Vertical Jump Height [Time frame: At the end of the 8-week pre-intervention control period and immediately after the 8-week FIFA 11+ intervention]
Secondary outcome measures (3)
- Session Rating of Perceived Exertion and Internal Training Load [Time frame: After each training session throughout the 8-week pre-intervention control period and the 8-week FIFA 11+ intervention period]
- Training Session Duration [Time frame: Recorded during each training session throughout the 8-week pre-intervention control period and the 8-week FIFA 11+ intervention period]
- Y-Balance Test Composite and Directional Reach Scores [Time frame: At the end of the 8-week pre-intervention control period and immediately after the 8-week FIFA 11+ intervention]
