MVPA levels for students based on low and high physical environment and social capital scores. The letters on the bars indicate significant group differences; groups with the same letter are significantly (p < 0.05) different from each other. For example, the letter “a” indicates that the low physical environment/low social capital group is significantly different from the low physical environment/high social capital group.
