Note: ① body composition markers (BM, BMI, BF%, WC, VAT, FFM, etc.), ② cardiorespiratory fitness (VO2max, includes yo-yo test distance or PACER times), ③ blood pressure (SBP and DBP), ④ lipid profile (TG, TC, HDL-C, LDL-C, etc.) and ⑤ glucose markers (BG, BI, HOMA-IR). Description of HIIT protocol: 2 × 10 × [1 min (90% HRmax):1 min (0)]:3 min (0) means 2 sets in each session, 3 min recovery between sets and perform 10 bouts of 1 min work at 90% HRmax and 1 min rest each set. BM: body mass, BMI: body mass index, BF%: body fat percentage, BG: blood glucose, BI: blood insulin, DBP: diastolic blood pressure, EE: energy expenditure, FFM: fat-free mass, HDL-C: high-density lipoprotein cholesterol, HIIT: high-intensity interval training, HOMA-IR: homeostasis model assessment, HRmax: maximal heart rate, LDL-C: low-density lipoprotein cholesterol, MAP: maximal aerobic power, MAS: maximal aerobic speed, MICT: moderate-intensity continuous training, MS: maximal speed, NA: not available, NR: not reported, OB: obese, OW: overweight, SBP: systolic blood pressure, TC: total cholesterol, TG: triglycerides, VAT: visceral adipose tissue, VT: ventilatory threshold, WC: waist circumference, VO2max: maximal oxygen uptake.
