The aim of this study was to assess the effect of physical exertion (treadmill) on mental performance (matching a comparison design). Nine pairs of monozygotic twins (boys aged 11 to 14 yr.) were randomly divided into two groups, one trained and one untrained, while eight boys of the same age served as a control group. The trained group underwent a specifically designed program lasting six months. The trained and untrained groups performed on the treadmill for 20 min. at a running speed intensity above their individual anaerobic thresholds. Mental performance was evaluated by analysing mean number of correct answers, time taken to reach correct answers (decision time), and wrong answers. A 3 x 2 (group x pre/posttest) analysis of variance with repeated measures on the last factor yielded no significant differences; however, significant pre- versus posttest differences on correct answers and decision times occurred among the exercised groups.
本研究的目的是评估体育锻炼（跑步机运动）对心理表现（匹配比较设计）的影响。九对同卵双胞胎（11至14岁男孩）被随机分为两组，一组接受训练，一组不接受训练，同时八名同龄男孩作为对照组。训练组接受了一个为期六个月的专门设计的项目。训练组和未训练组在跑步机上以高于各自无氧阈值的跑步速度强度跑20分钟。通过分析正确答案的平均数量、得出正确答案所需的时间（决策时间）和错误答案来评估心理表现。对最后一个因素进行重复测量的3×2（组×测试前/后）方差分析没有产生显著差异；然而，在运动组中，测试前和测试后在正确答案和决策时间上出现了显著差异。
