While park type is significantly associated with the type and intensity of physical activities, park size is also related to the level
of physical activity reported. The bivariate correlation between the number of physical activities mapped and park size for parks with five or more mapped activities is 0.83 (n = 48, p < 0.001). After controlling for park type, the partial correlation between the number of physical activities and park size remains significant at r = .79 (p < 0.001). Fig. 2 shows the summed MET equivalents for different physical activities mapped within each park, plotted by park size. The park size effect is most apparent for community parks and the linear parks where increased physical activity increases with park size, but this relationship is less obvious for neighbourhood and natural parks, although the relationship between physical activities and park size remains significant for neighbourhood parks only (r = .68, p < 0.001). Thus, the number of physical activities mapped is significantly related to park size, but park type is also a significant mediating variable in this relationship.
