A study of 174 parks in 25 U.S. cities found that parks with walking loops had 90% higher levels of moderate-to-vigorous physical activity in park users as compared to parks without walking loops. Parks with walking loops also had 80% more overall park users on average throughout the park, not just within walking loops.
