Investigated effects of aerobic exercise on a sample of 24 preschoolers. Thirty minutes of aerobic exercises were provided daily for a period of 8 weeks for a group of 12 children while the remaining 12 children engaged in freeplay on the school playground. The children were given pretests and posttests on the following measures: a submaximal exercise test on a pediatric bicycle (baseline and three workloads), an agility test, a health knowledge test, a self-esteem scale, and an observational measure of their gross-motor activity. Despite comparability on pretests, significant group X repeated measures effects suggested that the aerobic exercise group showed decreases in heart rate at all three workloads as well as increases in agility and self-esteem following the exercise program. These findings suggest that cardiovascular fitness, agility, and self-esteem can be facilitated in preschoolers by an aerobic exercise program.
研究了有氧运动对24名学龄前儿童样本的影响。一组12名儿童每天进行30分钟的有氧运动，持续8周，而其余12名儿童在学校操场进行自由活动。对儿童进行了以下测量的前测和后测：小儿自行车次最大运动测试（基线和三个工作量）、敏捷性测试、健康知识测试、自尊量表以及对其大肌肉活动的观察测量。尽管在前测中具有可比性，但显著的组×重复测量效应表明，有氧运动组在所有三个工作量下心率均下降，并且在运动计划后敏捷性和自尊有所提高。这些发现表明，有氧运动计划可以促进学龄前儿童的心血管健康、敏捷性和自尊。
