In recent years, athletes have frequently utilized Kinesio tape (KT) to enhance their performance. Despite widespread use, data regarding its efficacy and mechanism of action is lacking among healthy endurance athletes. This study aims to determine the effect of KT application on acute-onset muscle soreness and the extensibility of the calf muscles in endurance athletes.

The study followed a single-blinded one-arm crossover repeated-measures randomized controlled design and included fifty-five endurance athletes (mean age, 16.40±2.69) from different stadia in Delhi, India. Outcome measures, including the ankle dorsiflexion range of motion (ADFROM), were measured using a universal goniometer before, immediately after application of either KT or Sham tape, and after treadmill running. However, the pain due to acute-onset muscle soreness was measured using a numeric pain rating scale (NPRS) immediately, 10 min, and 30 min after treadmill running.
