Motor Skills and Autism: What Does the Evidence Say?

What is the effect of physical activity on motor skills of children with autism spectrum disorder?

A comprehensive systematic review and meta-analysis have evaluated the influence of physical activity on motor skills in children with autism. The results indicate that while physical activity programs can enhance strength, endurance, balance, and overall motor function, their impact on core motor coordination remains uncertain.

Some activities, such as swimming and horseback riding, have shown promise in improving psychomotor skills. These activities help promote gross motor proficiency, body coordination, and motor planning abilities, which are often delayed or impaired in children with ASD.

However, the evidence regarding their direct effect on fundamental motor coordination deficits, such as balance and precise movement control, is mixed. Many assessments face challenges with motor planning problems and developmental delays, making it difficult to measure definitive improvements.

Despite these limitations, engaging in regular physical activity continues to provide broad benefits. Improvements in muscle strength, endurance, and physical health are well-documented, especially when paired with specific motor skill interventions.

Types of Activities and Their Effects on Autism

What types of physical activities are beneficial for individuals with autism?

Research indicates that a variety of sports and exercises can significantly improve the developmental and behavioral symptoms in children and adults with autism spectrum disorder (ASD). For example, swimming is known to enhance psychomotor skills, increase adaptive behaviors, and foster social interaction. It also improves gross motor proficiency, which is often delayed in children with ASD.

Martial arts, such as karate, contribute to neurogenesis driven by increased brain-derived neurotrophic factor (BDNF) levels. These programs may help reduce communication difficulties and bolster memory and learning capabilities.

Horse riding, or equine therapy, provides unique benefits by improving social motivation, sensory sensitivity, and overall emotional regulation. It is particularly effective in reducing maladaptive behaviors and promoting body coordination.

Ball sports like minibasketball enhance cognitive skills and social integration, encouraging interpersonal interactions while improving motor coordination.

In addition, activities involving animals, such as horseback riding, serve as excellent opportunities for both verbal and nonverbal social engagement, helping children develop communication skills in a motivating environment.

Adapting these activities to suit individual sensory preferences and motor capabilities—such as incorporating routines, visual supports, and making activities enjoyable—can help promote sustained participation and developmental gains.

The Science Behind Physical Activity and ASD

What mechanisms and benefits of physical activity in managing autism symptoms are identified?

Physical activity influences the brain and body in multiple ways that can help reduce symptoms of autism spectrum disorder (ASD). One primary mechanism is its stimulation of neural pathways, which promotes neuroplasticity—the brain's ability to reorganize itself. Activities like swimming, martial arts, and horseback riding increase levels of neurotrophic factors such as Brain-Derived Neurotrophic Factor (BDNF), supporting neurogenesis and strengthening neural connections.

Engaging in regular exercise also affects neurotransmitter levels, including serotonin and dopamine. These chemicals play vital roles in mood regulation, attention, and social interactions. By boosting their levels, physical activity can help improve communication, reduce repetitive behaviors, and enhance social engagement.

Beyond neural effects, exercise impacts the gut microbiota—the diverse collection of microorganisms in the digestive system. Studies show that physical activity increases microbial diversity and decreases harmful bacteria like Clostridium perfringens. These microbial changes influence the gut-brain axis, a bidirectional communication network between the gastrointestinal system and the brain. Improvements in gut health can alleviate gastrointestinal issues common in children with ASD, further supporting overall behavioral and functional improvements.

Scientific evidence from systematic reviews and meta-analyses backs these mechanisms. They document that regular physical activity produces moderate to large benefits in core ASD symptoms, including better social skills, less stereotypic behavior, and improved motor functions. In sum, exercise offers a comprehensive approach, modulating neural structures, chemical signaling, and microbiota to help manage autism symptoms effectively.

Research Evidence and Meta-Analyses on Exercise in Autism
