About this study
Official title: The Relationship Between Lower Extremity Strength, Dynamic Balance, and Core Endurance in Elite Youth Rowers: A Cross-Sectional Observational Study
This study aims to investigate the relationship between lower extremity isokinetic strength, dynamic balance, and core muscle endurance in elite adolescent rowers aged 16-18. A total of 68 athletes (32 males, 36 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.
Read the detailed description
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 16-18. 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.
Lower 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.
The 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.
This 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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Male Athletes | Elite male adolescent rowers (n=36), aged 16-18, participating in national-level rowing training at least 5 times per week. | |
| Female Athletes | Elite female adolescent rowers (n=32), aged 16-18, participating in national-level rowing training at least 5 times per week. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Composite Y Balance Test Score (%)
Dynamic balance will be assessed using the Y Balance Test. Reach distances in three directions will be normalized to limb length, and a composite balance score will be calculated. The outcome will be used to compare balance performance across sex groups.
Measured: Cross-sectional assessment at baseline (single visit)
Isokinetic Quadriceps Peak Torque at 60°/s (Nm)
Peak torque of the dominant quadriceps muscle will be measured using an isokinetic dynamometer at an angular velocity of 60°/s. The outcome will be recorded in Newton-meters (Nm) and used to analyze muscle strength differences between groups.
Measured: Cross-sectional assessment at baseline (single visit)
Core Extensor Endurance Time (seconds)
Trunk extensor endurance will be evaluated using the McGill Trunk Extensor Endurance Test. Participants will maintain a horizontal prone posture over the edge of a bench with the pelvis stabilized. The maximum time (in seconds) that the position can be held with proper form will be recorded as the endurance score.
Measured: Cross-sectional assessment at baseline (single visit)
