About this trial
acilitative kinesio taping (KT) is commonly used by athletes to support muscle performance and delay fatigue. However, evidence regarding its effects on muscle endurance and oxygenation remains inconsistent. This study aims to investigate the acute effects of facilitative KT applied to the gastrocnemius muscle on heel-rise endurance performance and local muscle oxygenation in healthy young adults.
In this randomized crossover trial, participants will complete two experimental sessions: one with facilitative kinesio taping and one with sham taping. After taping application, participants will perform a single-leg heel-rise test to task failure. Muscle oxygenation will be continuously monitored using a portable near-infrared spectroscopy device. The findings of this study may contribute to understanding whether kinesio taping has immediate physiological and performance-related effects on calf muscle endurance.

Treatments tested in this trial
Kinesio Taping
DeviceY-shaped Kinesio Tex elastic tape applied to the gastrocnemius muscle with approximately 50% stretch following muscle facilitation principles.
Sham Taping
DeviceY-shaped Hypafix tape applied to the gastrocnemius muscle without stretch using the same anatomical configuration.
Treatment groups
Trial outcomes
Primary outcomes
Total Concentric Work (J)
Total concentric (positive) mechanical work (Joules) performed during a metronome-guided single-leg heel-rise test to task failure on the dominant limb. Work output will be measured using the Calf Raise App (computer-vision-based motion analysis).
Percent Change in Gastrocnemius Muscle Oxygen Saturation at 20 Seconds (%ΔSmO₂_20s)
Secondary outcomes
Total number of single-leg heel-rise repetitions
Peak Heel-Rise Height (cm)
Maximum heel-rise height (cm) achieved during the single-leg heel-rise test, measured using the Calf Raise App.
Concentric Power (W)
Mean concentric power output (Watts) generated during the single-leg heel-rise test, measured using the Calf Raise App.
End-Exercise Muscle Oxygen Saturation (SmO₂_end)
Muscle oxygen saturation (SmO₂) value recorded at the point of task failure during the heel-rise test.
