The study was conducted to investigate the effects of different Kinesio taping directions on dynamic muscle endurance. This randomized, double-blind, crossover study was implemented on 27 healthy male subjects. Before the study, personal and demographic information of the volunteers were recorded and muscle strength was evaluated in the biceps curl position with 1 maximum repetition technique. One week after this first evaluation muscle endurance was evaluated by counting the accurate elbow flexions completed in biceps curl position with 80% weight of 1 maximum repetition recorded in the first evaluation. Following this second evaluation facilitation, inhibition, and placebo tapings were applied to all the 27 subjects who were randomly assigned into 3 groups sequentially with an interval of two days. The sequence of taping technique to be used for the groups were also randomly determined and applied to the M. Biceps Brachii and muscle endurance was evaluated with the same method half-hour after the tape was applied. All the evaluations were performed by the same evaluator who was blind to the taping technique.

Facilitation taping was applied from the origins of the muscle to the insertion. Inhibition taping was applied from the insertio of the muscle to the origin. Facilitation taping and inhibition taping was applied on the target tissue with 25% tension. Y-band was used during facilitation taping and inhibition taping. It was applied to individuals with shoulder mild abduction, external rotation, elbow extension and supination position. Placebo taping was applied while in a resting position. In placebo taping, it was applied using two I bands in horizontal direction. In placebo taping, no tension was applied to the tapes. Evaluations were made while the subjects were standing. The biceps curl exercise position starts with the palms facing the trunk. Elbow flexion is completed by making full range of motion. The cases were randomized into 3 groups: group-1 facilitation taping, group-2 inhibition taping and group-3 placebo taping.The treatment sequence to be applied to the patients was determined by randomization. Facilitation, inhibition and placebo banding were applied to the patients, respectively. Accordingly, inhibition and placebo taping was applied to the cases that started with the facilitation taping. Placebo and facilitation banding were applied to the patients that started with inhibition banding, respectively. Facilitation and inhibition banding was applied to the cases that started with placebo banding, respectively. During the evaluation, banding application was kept by wearing plenty of clothes. Evaluators and subjects participating in the study did not have knowledge and experience about the taping method.
