Cold application is commonly used before strenuous exercise due to its hypalgesic effects. Some have questioned this procedure because of reports that cold may reduce isokinetic torque. However, there have been no investigations of actual physical performance following cold application. The purpose of this study was to determine if a 20-minute ice immersion treatment to the foot and ankle affected the performance of three agility tests: the carioca maneuver, the cocontraction test, and the shuttle run. Twenty-four male athletic subjects were tested during two different treatment sessions following an orientation session. Subjects were tested following a 20-minute 1 degrees C ice immersion treatment to the dominant foot and ankle and 20 minutes of rest. Following each treatment, subjects performed three trials of each agility test, with 30 seconds rest between each trial, and 1 minute between each different agility test. The order in which each subject performed the agility tests was determined by a balanced Latin square. A MANOVA with repeated measures was used to determine if there was an overall significant difference in the agility times recorded between the cold and control treatments and if the order of the treatment sessions affected the scores. Although the mean agility time scores were slightly slower following the cold treatment, cooling the foot and ankle caused no difference in agility times. Also, there was no difference resulting from the treatment orders. We felt that the slightly slower scores may have been a result of tissue stiffness and/or subject's apprehension immediately following the cold treatment. Cold application to the foot and ankle can be used before strenuous exercise without altering agility.
冷疗在剧烈运动前被广泛应用,因为它具有镇痛效果。有人对这种方法提出了质疑,因为有报道称寒冷可能会降低等速扭矩。然而,还没有对冷疗后实际身体表现的调查。本研究的目的是确定对足部和踝关节进行 20 分钟的冰敷处理是否会影响三种敏捷性测试的表现:卡里奥卡动作、协同收缩测试和穿梭跑。24 名男性运动受试者在两个不同的治疗阶段进行了两次定向测试。在对主导脚和脚踝进行 20 分钟 1 摄氏度的冰敷处理并休息 20 分钟后,对受试者进行了测试。在每次治疗后,受试者进行了三次敏捷性测试,每次测试之间休息 30 秒,不同敏捷性测试之间休息 1 分钟。每位受试者进行敏捷性测试的顺序由平衡拉丁方确定。采用重复测量的 MANOVA 来确定在冷疗和对照治疗之间记录的敏捷时间是否存在整体显著差异,以及治疗顺序是否会影响分数。尽管在冷疗后,敏捷时间的平均得分略慢,但冷却足部和踝关节不会导致敏捷时间的差异。此外,治疗顺序也没有差异。我们认为,稍慢的得分可能是由于组织僵硬和/或受试者在冷疗后立即出现的恐惧。在剧烈运动前,可以对足部和踝关节进行冷疗,而不会影响敏捷性。
