LF = low frequency; HF = high frequency; LF/HF = low frequency/high frequency ratio, nu: normalized units; WC = waist circumference; HOMAR-IR = Homeostasis Evaluation Model; MVPA = average of minutes per day spent in vigorous physical activity (>100 mg); ST = sedentary time; TEV = total energy value (kcal/day). .
