Brief Summary

This study aims to evaluate the acute effect of standardized taping of the dominant ankle on lower limb asymmetry during the countermovement jump (CMJ) test in healthy judokas. Forty healthy, active judokas aged 18-35 years will perform CMJ testing under two conditions: with and without standardized ankle taping. Lower limb asymmetry and selected biomechanical parameters will be measured using the Meloq EasyBase force platform. The results may improve understanding of the effects of ankle taping on jumping performance and contribute to injury prevention strategies in sport.

Conditions

Ankle Stability

Outcome Measures

Primary Outcomes (1)

• Lower-Limb Asymmetry During the Countermovement Jump Test

  Lower-limb asymmetry will be assessed using force plate measurements during the countermovement jump test.

  Immediately after standardized ankle taping and without taping (single study visit)

Study Arms (2)

standardized Ankle Taping

EXPERIMENTAL

Participants perform the countermovement jump test after standardized taping of the dominant ankle. jump heigh, force, and lower-limb asymmetry are assessed.

Device: Standardized Ankle Taping

No Ankle Taping

ACTIVE COMPARATOR

Participants perform the countermovement jump test without ankle taping. Jump height, force, and lower-limb asymmetry are assessed.

Other: No ankle taping

Interventions

Standardized Ankle Taping DEVICE

Standardized taping was applied to the dominant ankle before performing the countermovement jump test to evaluate its acute effect on lower-limb asymmetry and jump performance.
