For kids with ADHD, A walk in the park = Ritalin
Children with ADHD had significantly improved concentration following the walk in the park compared with the walks in both the downtown and neighbourhood settings. The park walk resulted in improved performance in the Digit Span Backwards test: children were on average six-tenths of a digit better at the test than after the downtown walk and seven-tenths of a digit better than following the neighbourhood walk. There were no significant differences in concentration between the two urban walks. Children also rated the park walk as ‘fun’ significantly more often than the two urbanised walks.
