The purpose of this study was to compare the effects of two semirigid prophylactic ankle stabilizers on vertical jump, 80-ft sprint, shuttle run, and four-point run performance. Eight male and seven female high school basketball players, who denied prior ankle injury and prophylactic ankle stabilizer experience, completed the four performance events under the conditions of Active Ankle Training Brace, Aircast SportStirrup, and nonbraced control. Data analyses consisted of four 1 × 3 ANOVAs with repeated measures on the independent variable of brace condition. Results of the analysis revealed no significant differences among the experimental conditions for any of the performance events tested. In conclusion, the Active Ankle Training Brace and Aircast SportStirrup did not facilitate or adversely affect performance involving speed, agility, and vertical jump of high school basketball players.
