All subjects wore an eye mask and the taped leg was covered by clothes for preventing subjects and researchers from identifying different tapings due to double-blinding. Subjects layed down on the mat in a supine position with the hip flexed 30º and the knee flexed 60º. Y type tape was applied from a point 10 cm below the anterior superior iliac spine, bisected at the junction between quadriceps femoris tendon and the patella, ending at its inferior side. And another Y type tape was applied from the tibial tuberosity, bisected at the junction between patella tendon and the patella, ending at its superior side. The first 5 cm tape was not stretched and acted as the anchor. I type tapes were applied downward and inward to the superior and inferior meniscus of the patella respectively.

Placebo tapes (3M tape) were applied with same method with Kinesio taping.

In case of the no taping condition, the subject was treated along the same procedure which was closed subject's eyes with eye mask and covered the legs with clothes although applied anything on their legs. It might be able to minimize the error, because the researchers did not realize which condition the subject had.

This study was conducted in a randomized crossover double-blind design. Each subject was tested for muscular power, strength, endurance, and fatigue of the lower extremities under three conditions: 1) NT (no taping), 2) PT (placebo taping, 3M tape) and 3) KT (Kinesio taping). For allocation of treatment sequence, the participants drew straws for which treatment first (each treatment indicated different numbers).

- variables:(1) Body weight and height (Detecto DR400C platform scale (Webb City, MO) and Seca S-214 height rod (Hanover, MD), respectively), (2) Waist and hip circumference (Gulik tape measure), (3) % Body fat (bioelectrical impedance analysis, RJL Quantum X).

Peak power and mean power were measured with automatic Power cycle (Powercycle, USA). The subjects started from rest and accelerated maximally for approximately 3-4 seconds. Data was recorded for 6.5 pedal revolutions, and the increase in kinetic energy resulting from the acceleration of the ergometer flywheel was averaged over every pedal revolution and used to calculate power. The highest power and mean power (average two of the highest values) recorded during a pedal revolution was defined as Pmax and Pmean respectively.
