^a n = 41; ^bn = 41. Valid accelerometer data were available for 49 of the 54 participants. Valid data for blood parameters were available for 42 of the 54 participants. The number of risk factors for CVD was calculated only for those participants with complete risk factor data. PA: physical activity; LPA: light physical activity; MVPA: moderate-to-vigorous physical activity; SB: sedentary behavior; BMI: body mass index; WC: waist circumference; SBP: systolic blood pressure; DBP: diastolic blood pressure; HDL: high density lipoprotein; TC: total cholesterol; GLU: glucose; CVD: cardiovascular disease.
