Brief Summary

This study aims to investigate the effects of a structured training intervention on selected physical performance parameters in athletes. The primary objective is to determine whether the intervention leads to measurable improvements in performance outcomes such as balance, strength, sprint, change of direction, or jump performance. Participants will undergo baseline performance assessments before the intervention period. Following the baseline testing, participants will complete a supervised training program lasting several weeks. After the intervention, the same performance tests will be repeated under standardized conditions to evaluate changes in performance. All assessments will be conducted by trained researchers using validated measurement tools in a controlled training environment. The findings of this study are expected to provide evidence regarding the effectiveness of the training intervention and contribute to the development of evidence-based training strategies for athletes.

Outcome Measures

Primary Outcomes (2)

• Dynamic Balance Performance (Y-Balance Test Composite Score)

  Baseline and after 6 weeks of eccentric training

• Dynamic Balance Performance (Y-Balance Test Composite Score)

  Dynamic balance performance will be assessed using the Y-Balance Test. The composite score will be calculated based on reach distances in the anterior, posteromedial, and posterolateral directions and normalized to limb length. Measurements will be performed before and after the training intervention under standardized testing conditions.

  Baseline and immediately after the 6-week training intervention

Behavioral: Accentuated Eccentric Training

Interventions

Accentuated Eccentric Training BEHAVIORAL

Participants will complete a structured accentuated eccentric training program designed to improve neuromuscular performance. The intervention will be performed using resistance exercises in which the eccentric load is greater than the concentric load. Training sessions will be supervised by qualified researchers and conducted over a defined intervention period. All participants will follow the same standardized training protocol under controlled conditions.
