MVPA >3 METSs	27.2 ± 25.3	49.6 ± 40.5	58.8 ± 41.4	70.9 ± 41.1

METs = metabolic equivalents; PA = physical activity; MVPA = moderate-to-vigorous physical activity.
Values represented as means ± standard deviation. Comparisons between gender and race groups were completed using independent t-tests when data was normally distributed and Mann-Whitney U-test for non-normally distributed data.
^a p < 0.05 Girls vs Boys.
^b p < 0.05 Black vs White.
