We evaluated the effect of different ankle support devices on athletic performance. Thirty varsity college athletes were tested with both ankles supported by taping, Swede-O brace, Kallassy brace or left unsupported. The athletes performed four events: broad jump, vertical leap, 10 yard shuttle run, and 40 yard sprint. The events and appliances were randomized to prevent bias by fatigue. Compared to the results when no support was used, ankle taping resulted in a significant decreased performance in the vertical jump (4%), shuttle run (1.6%), and sprint (3.5%) (P less than 0.05). Use of the Swede-O brace decreased performance in the vertical jump (4.6%), broad jump (3.6%), and time of the sprint (3.2%). Results using the Kallassy brace showed a decrease in the vertical jump (3.4%) when compared to no support. The test results of the shuttle run with taping were slower than the Kallassy brace (P less than 0.05). Wearing the Swede-O brace caused the athletes' broad jump distance to decrease more than the Kallassy brace (P less than 0.05). Subjective questionnaires supported the Kallassy brace as the most comfortable support and the one that decreased performance the least. Taping of the ankles is universally accepted for ankle prophylaxis. This study has shown a decrease in performance when ankles are taped compared to ankles with no protection. Since the decreases in performance caused by ankle braces are minor, this should not be used as a criterion for selection of prophylactic support compared to taping.
我们评估了不同脚踝支撑装置对运动表现的影响。30名大学代表队运动员的双侧脚踝分别使用胶带、瑞典式护具、卡拉西护具进行支撑，或一侧脚踝不做支撑进行测试。运动员进行了四项运动：立定跳远、垂直纵跳、10码穿梭跑和40码短跑。运动项目和支撑装置随机安排，以防止疲劳导致的偏差。与不使用支撑装置时的结果相比，使用胶带支撑脚踝会使垂直纵跳（4%）、穿梭跑（1.6%）和短跑（3.5%）的表现显著下降（P小于0.05）。使用瑞典式护具会使垂直纵跳（4.6%）、立定跳远（3.6%）和短跑时间（3.2%）下降。与不做支撑相比，使用卡拉西护具使垂直纵跳下降了3.4%。使用胶带支撑时的穿梭跑测试结果比使用卡拉西护具时慢（P小于0.05）。佩戴瑞典式护具导致运动员的立定跳远距离下降幅度大于卡拉西护具（P小于0.05）。主观问卷调查显示，卡拉西护具是最舒适的支撑装置，对运动表现的降低也最小。脚踝贴扎普遍用于预防脚踝损伤。本研究表明，与不做保护的脚踝相比，贴扎脚踝时运动表现会下降。由于护具导致的运动表现下降较小，与贴扎相比，这不应用作选择预防性支撑装置的标准。
