A total of 68 athletes (31 males, 37 females) will be assessed through standardized protocols involving isokinetic testing, the Y Balance Test, and McGill Core Endurance Tests. The study aims to contribute to performance monitoring and injury prevention strategies in rowing sports.', 'detailedDescription': 'This observational cross-sectional study aims to investigate the relationships between lower extremity muscle strength, dynamic balance, and core endurance in elite adolescent rowers aged 14-17. A total of 68 rowers (32 females, 36 males) licensed by the Turkish Rowing Federation were included. All participants had a minimum of two years of rowing experience and trained at least four days per week.\n\nLower extremity muscle strength was assessed using isokinetic dynamometry at angular velocities of 60°/s and 300°/s. Core endurance was evaluated using the McGill Core Endurance Test Battery, including trunk flexor, extensor, and lateral plank tests. Dynamic balance was assessed via the Y Balance Test and normalized to leg length.\n\nThe study also examined potential sex-based differences in neuromuscular performance and investigated inter-variable correlations among muscle strength, balance, and core endurance. In addition, asymmetry in dynamic balance performance was analyzed as a risk factor for performance and injury.\n\nThis study is expected to provide practical insights for sports physiotherapists and coaches working with adolescent rowers, particularly in optimizing performance and designing sex-specific injury prevention strategies.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT'], 'maximumAge': '18 Years', 'minimumAge': '16 Years', 'genderBased': True, 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'The study population consists of 68 elite adolescent rowers (32 females, 36 males) aged 16 to 18 years, actively competing and training under the Turkish Rowing Federation.
