Abstract: BACKGROUND: A number of studies have assessed the effect of kinesiology tape (KT) application with respect to the delayed onset of muscle fatigue. OBJECTIVE: To determine the effects of direction of KT application on the delayed onset of quadriceps fatigue. METHODS: An isokinetic dynamometer was used to induce concentric quadriceps fatigue in 15 healthy participants prior to applying KT. The KT was randomly applied on the muscles in two possible orientations: from origin to insertion or from insertion to origin. After the application the number of repetitions of knee extension required to induce fatigue was recorded. RESULTS: Regardless of the direction of application, the number of repetitions needed to generate muscle fatigue increased after the KT was applied. On the other hand, there was no significant difference between taping directions. CONCLUSIONS: KT application on the quadriceps delays the onset of its isokinetically-induced fatigue, irrespective of the direction of application. Therefore, using KT may be considered as a possible technique in those tasks where fatigue may seriously hamper performance.
