Animal and human research show that aerobic exercise helps the brain by improving learning and memory (Kobilo, Yuan, & van Praag, 2011), which has implications for the development of an effective autism therapy, but also in the development of a healthy environment in the home.
Children with autism generally spend less time than their typically developing peers in physical activity (Bandini et al., 2013; Must et al., 2013). Even when they display hyperactive behavior, their physical activity is not necessarily contiguous, sustained, directed, or functional, but is typically maladaptive.
The negative consequences for children with autism who do not participate in physical exercise are both immediate and long-term (National Center for Health Statistics, 2012).
The U.S. Centers for Disease Control and Prevention (CDC) recommend 60 consecutive minutes of daily exercise for children (Arem et al., 2015). Of those 60 minutes, most should be aerobic activity. The American Heart Association recommends that aerobic activity be done at 50-85% of the child’s maximum target heart rate (Physical Activity and Health: A Report of the Surgeon General, 1996).
Although the exercise and activity regimen proposed by the CDC is ideal, it is the unfortunate reality that physical exercise and motor activity participation can be particularly difficult for children with autism because many of them experience motor difficulties (Ming, Xue, Michael, & Wagner, 2007; Pope, Bierman, & Mumma, 1991). In some cases, they avoid physical activity altogether. Activities may be either too noxious (in terms of the sensory requirements for the activity) or too difficult to experience success in coordination-based activities (Leekam, Nieto, Libby, Wing, & Gould, 2007). Therefore, successful participation in physical exercise to promote health and wellness of children with autism may be directly linked to resolving their sensory-motor difficulties.
In our experience with autism therapy, engaging a child with autism in physical activity that is sustained and continuous, with some sort of productive or play-based and directed goal in mind, we usually find a calmer child and one who is ready to be engaged in other social experiences. It seems to fulfill a need that many of these children have.
Participation in Sensory Enrichment Therapy for autism (SET) (Woo & Leon, 2013) has been shown to decrease motor apraxia and increase motor coordination, in addition to many other functional gains (Woo, Donnelly, Robin, & Michael, 2015). This strongly indicates that participation in SET has the potential to help ameliorate sensory and motor dysfunction in children with autism. A secondary benefit may be the increase in healthy participation of physically exertive activities that will contribute to reducing the ever-increasing health crises that face our children today.
One of the tenants of Mendability’s Sensory Enrichment Therapy for autism is participation in physical exercise (Erickson, Leckie, & Weinstein, 2014; Gomez-Pinilla & Hillman, 2013).
