The necessity of promoting physical activity in individuals with Autism Spectrum Disorder (ASD) has been emphasized for decades. One of the barriers to participate in physical activity for individuals with ASD is limited interest and motivation. Therefore, understanding the motivation to exercise in this population is important. The objective was to determine the effect of using contingent reinforcement in the form of watching a preferred DVD to increase duration of time pedalling on a stationary bicycle within their predetermined target heart rate zone (THRZ) in children with ASD. Using a crossover design, seven participants (11 2.7 years) who were diagnosed with ASD were randomly assigned to either Group A or B. Time spent pedalling on a bicycle within the THRZ was analysed using a linear mixed-effect model with Bonferroni adjustments. The results showed that the DVD intervention motivated children with ASD to exercise for more than 10 minutes in moderate to vigorous physical activity compared to when they were exercising without watching a DVD. This result is significant as number of studies have revealed that 10 minutes of exercise could bring improvements in activities of daily living such as behaviors and academic performance in school.
几十年来，人们一直强调促进自闭症谱系障碍（ASD）患者进行体育活动的必要性。ASD患者参与体育活动的障碍之一是兴趣和动机有限。因此，了解这一人群的运动动机很重要。目的是确定使用观看喜爱的DVD这种偶然强化形式，对提高ASD儿童在其预定目标心率区（THRZ）内骑固定自行车的时长的影响。采用交叉设计，将七名被诊断为ASD的参与者（11±2.7岁）随机分为A组或B组。使用带有Bonferroni校正的线性混合效应模型分析在THRZ内骑自行车的时长。结果表明，与不看DVD锻炼时相比，DVD干预促使ASD儿童在中度至剧烈体育活动中锻炼超过10分钟。这一结果意义重大，因为多项研究表明，10分钟的锻炼可以改善日常生活活动，如行为和学校学习成绩。
