Bike-Riding Training may Improve Communication Skills and Stereotyped Behavior in Adolescents With Autism.

Researchers taught 50 teenage boys with autism how to ride bicycles over 12 weeks, with some groups practicing once per week and others three times per week. Compared to boys who didn't receive bike training, those who learned bike-riding skills showed better communication and fewer repetitive behaviors. These improvements lasted at least one month after training ended, suggesting bike-riding could be a helpful activity for autistic teenagers.

This randomized controlled trial examined the effects of 12-week bicycle-riding training programs on communication skills and stereotyped behaviors in 50 adolescent boys with autism (mean age 13.3 years). Participants were divided into experimental groups receiving different training frequencies (1 vs 3 sessions/week) and intensities (low vs high), plus a control group. Using the GARS-2 assessment, researchers found significant improvements in both stereotyped behavior and communication skills in intervention groups compared to controls at post-test and one-month follow-up. Results suggest that bicycle-riding training, regardless of specific intensity or frequency parameters, can meaningfully reduce stereotyped behaviors and enhance communication skills during the critical adolescent period.

Bicycle-riding training appears to be a practical, accessible intervention that can improve core autism characteristics during adolescence. The flexibility in training parameters (frequency/intensity) makes it adaptable to individual needs and family schedules, potentially supporting broader implementation in therapeutic and community settings.

Study limited to adolescent boys only, so generalizability to girls and other age groups unclear. No details provided about randomization procedures, blinding, or control group activities. Long-term follow-up beyond one month not assessed. Mechanism underlying improvements not investigated.

This research aimed to establish whether 12 weeks of bicycle-riding skills exercises with massed and distributed practice frequency at low and high intensity affect communication performance and stereotyped behavior among adolescent boys with autism. Fifty autistic boys aged 13.3 ± 1.32 years participated in the study. The participants were divided into homogeneous experimental groups (N = 10) with dissimilar training frequencies and intensities, along with a control group. Pre-tests using the GARS-2 test were administered to assess stereotyped behavior and communication skills, followed by post-tests and a one-month follow-up.

Non-parametric Kruskal Wallis and ANCOVA results at a significance level of 0.05 showed that there was a significant difference in the post-test of stereotyped behavior and communication skills (p = 0.001 and p = 0.002, respectively) and follow-up test one month later (p = 0.003, p = 0.048, respectively) between the intervention and control groups after performing bike riding skills exercises with low and high intensities and frequencies (one and three sessions per week). Regardless of the intensity and frequency, bike riding skills training during the critical period of adolescence can significantly reduce stereotyped behaviors and enhance communication skills, which can also support positive development in other domains for individuals with autism.
