Values are reported as mean ± standard deviation. Abbreviations: BMI, body mass index; MVPA, moderate to vigorous physical activity; V̇O
2max, maximal oxygen uptake; HR
max, maximal heart rate; %V̇O
2max, percentage of maximal oxygen uptake; VT, ventilatory threshold; RPE
max, maximal rating of perceived exertion.* Physical activity data are presented for 15 participants (8 boys).
