Acute Effect of Standardized Ankle Taping on Lower Limb Asymmetry During Countermovement Jump in Healthy Judokas
A study testing Standardized Ankle Taping and No ankle taping in people with Ankle Stability, run by Triggerimpulse centar.
Trial 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. Read more about this study

About this study
Official title: Acute Effect of Standardized Taping of the Dominant Ankle on Lower Limb Asymmetry During the Countermovement Jump Test in Healthy Judokas
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.
Read the detailed description
Ankle sprains are among the most common musculoskeletal injuries in sports and may impair proprioception, postural control, and functional performance. Standardized ankle taping is widely used to improve joint stability and reduce the risk of recurrent injury; however, its acute effects on lower limb asymmetry during jumping remain unclear.
This interventional, within-subject study will include 40 healthy, active judokas aged 18-35 years. Participants will complete countermovement jump (CMJ) testing under two randomized conditions: without ankle taping and with standardized taping applied to the dominant ankle. Following taping, participants will complete a 5-minute familiarization walk before testing.
Biomechanical variables will be assessed using the Meloq EasyBase force platform. The primary outcome is lower limb asymmetry in net propulsive impulse during the CMJ. Secondary outcomes include asymmetry in peak propulsive force, asymmetry in peak propulsive power, and jump height.
The findings may contribute to evidence-based recommendations regarding the use of ankle taping for injury prevention and performance optimization in healthy athletes.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Standardized Ankle TapingDevice
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.
No ankle tapingOther
Participants performed th countermovement jump test without ankle taping
| Study group | Role | What they receive |
|---|---|---|
| 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. Receives: 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. Receives: Other: No ankle taping |
What is being measured
The primary outcome is the main question the study is designed to answer.
Lower-Limb Asymmetry During the Countermovement Jump Test
Lower-limb asymmetry will be assessed using force plate measurements during the countermovement jump test.
Measured: Immediately after standardized ankle taping and without taping (single study visit)
