Note: Values represent mean ± standard deviation, adjusted for age, gender and average daily aerobic steps.
Means with a different letter superscript indicate statistical significance between the groups compared (P < 0.05).
BMI- body mass index.
%BF- percentage body fat.
WC- waist circumference.
SBP- systolic blood pressure.
DBP- diastolic blood pressure.
BC- blood cholesterol.
BG- blood glucose.
