There is an age-related decline in children’s physical activity levels as they progress through primary school, according to a British Heart Foundation-funded study. Researchers at the University of Bristol found that children spent less time doing physical activity and spent more time sedentary from Year 1 (aged 5-6) to Year 4 (aged 8-9).
