NCT07320027

Brief Summary

The purpose of this randomized controlled trial is to compare the acute effects of static stretching, dynamic stretching, and proprioceptive exercises on proprioception, muscle strength, balance, and explosive power in young athletes. The study aims to determine how different stretching and exercise modalities influence short-term performance parameters. The primary questions this study aims to answer are: Do static stretching, dynamic stretching, and proprioceptive exercises have different acute effects on proprioception? Do these interventions cause different changes in muscle strength, balance, and explosive power? Researchers will compare the static stretching, dynamic stretching, and proprioceptive exercise groups to determine which method produces greater improvements in the measured performance parameters. Participants will: Perform one of the three assigned exercise protocols according to a standardized warm-up procedure Undergo pre- and post-exercise assessments, including: Proprioception (measured with an isokinetic device) Muscle strength (measured with an isokinetic device) Balance (measured with a Y balance test and BESS balance test) Explosive power (measured with the Sargent Vertical Jump Test)

Outcome Measures

Primary Outcomes (2)

  • Knee Joint Position Sense Error (degrees)

    Angular joint position matching error (degrees) measured using the ISOMED 2000 isokinetic dynamometer with passive reproduction of target angles.

    Baseline and 1 day

  • Peak Torque during Knee Extension (Nm)

    Peak torque (Nm) during knee extension assessed using the ISOMED 2000 isokinetic dynamometer. Testing was performed in concentric mode at 60 deg/s.

    Baseline and 1 day

Secondary Outcomes (14)

  • Peak Torque during Knee Flexion (Nm)

    Baseline and 1 day

  • Total Work during Knee Extension (J)
