The primary goal of this study was to investigate the effects of attention-deficit/hyperactivity disorder (ADHD) medications on exercise-induced hypoalgesia (EIH), heart rate, and perceived exertion. Thirty college-age students (10 Controls, 10 ADHD diagnosis, and 10 ADHD diagnosis with medications) completed 2 sessions: 1) a maximal testing session and 2) an experimental session consisting of 3 consecutive dynamic resistance exercise circuits comprised of 12 repetitions of 9 exercises at 60% of 1-repetition maximum using a 1:1 work to rest ratio. All participants, regardless of condition (Controls vs. ADHD without medications vs. ADHD with medications), displayed EIH accompanied by an increase in blood lactate, heart rate, and perceived exertion for the duration of the exercise bout. Therefore, the effects of resistance exercise are not altered by ADHD diagnosis or psychostimulant medication use for ADHD. These findings are intriguing given the known ergogenic and hypoalgesic effects of caffeine, a less potent stimulant.
本研究的主要目的是调查注意力缺陷多动障碍(ADHD)药物对运动诱发痛觉减退(EIH)、心率和自觉运动强度的影响。30名大学生(10名对照组、10名被诊断为ADHD者和10名服用ADHD药物的被诊断为ADHD者)完成了2个阶段:1)一次最大测试阶段;2)一个实验阶段,该阶段由3个连续的动态抗阻运动循环组成,每个循环包含9项运动,每项运动重复12次,强度为1次重复最大值的60%,工作与休息比例为1:1。所有参与者,无论处于何种状态(对照组、未服用药物的ADHD患者、服用药物的ADHD患者),在运动期间均表现出运动诱发痛觉减退,同时伴有血乳酸、心率和自觉运动强度增加。因此,抗阻运动的效果不会因ADHD诊断或用于治疗ADHD的精神兴奋剂药物使用而改变。鉴于已知咖啡因(一种效力较弱的兴奋剂)具有促力和痛觉减退作用,这些发现很有趣。
