Abstract
International Journal of Exercise Science 11(1): 1086-1095, 2018. The objective was to examine the effect of Active Ankle T1TM ankle braces on the timing of muscular activation of the upper leg in female volleyball athletes during a one-legged landing task. Fourteen healthy female varsity volleyball athletes participated in this study. Each signed a participant recruitment form, consent form, a Physical Activities Readiness Questionnaire (PAR-Q) and completed the injury screening form. A warm up was completed followed by two practice jumps. Each participant was randomly assigned and counterbalanced to a condition to begin with (no brace or brace). Once the warm up and practice trials, the participant applied the appropriate condition. A researcher applied DelsysTM electrodes to the participant’s left leg on the vastus medialis and biceps femoris. The jumps consisted of a two foot approach, a two foot takeoff, and a landing on the left leg. The participants completed three trials in the first condition and then three in the opposite condition. A VertecTM device was used to increase participant’s motivation. The differences in timing of the muscular activation of the biceps femoris and vastus medialis were analyzed. A repeated measures t-test was used to analyze the data. There was no significant difference in timing of muscular activation of the biceps femoris and vastus medialis between the brace condition and no brace condition. The findings of this study show that the use of Active Ankle T1TM ankle braces do not increase the risk of injury to the anterior cruciate ligament in terms of timing of muscular activation.
