背景:注意力缺失过动症(attention deficit hyperactivity disorder,ADHD)是一种普通的儿童疾病,影响到大约11%的美国儿童。已有研究支持一段时间的运动有益于儿童的认知表现,数量有限的研究已证明这种影响对ADHD患儿也有效。本研究旨在探讨急性运动对ADHD患儿和普通儿童认知表现的影响。方法:让ADHD患儿和普通儿童接受为期2天、顺序平衡随机的治疗,其中一天为30 min对照状态,另一天为中等强度运动。治疗后对受试者进行认知测试。结果:运动使受试者在斯特鲁测试(Stroop Test)3种情况下的表现均有显著提高,但对伦敦塔测试(Tower of London Test)和连线测试(Trail Making Test)表现影响不大。结论:一段时间的运动能改善ADHD患儿和正常儿童的处理速度和抑制控制,但对其计划和定势转换能力没有影响。
Background: attention deficit hyperactivity disorder (ADHD) is an ordinary childhood disease affecting about 11% of U.S. children. Previous studies have supported the exercise of children for some time in their cognitive performance, and a limited number of studies have demonstrated that this effect is also valid in children with ADHD. This study aimed to investigate the effects of acute exercise on cognitive performance in children with ADHD and children. Methods: Children with ADHD and normal children were enrolled in a two-day, balanced, randomized sequence of treatment. One day was 30 min and the other day was moderate-intensity exercise. Subjects were tested for cognitive tests after treatment. RESULTS: Subjects significantly improved their performance in all three Stroop Test cases, but did not affect the Tower of London Test or Trail Making Test Big. CONCLUSIONS: Exercise over time has been shown to improve the rate of treatment and suppression of ADHD and normal children, but has no effect on their ability to plan and set-the-clock shifts.
