ΔThe variation between parameters assessed at baseline (preintervention) and postintervention.
**p<0.01; significant difference from control group.
BMI, body mass index; FM, fat mass; FFM, fat-free mass; HOMA-IR, homoeostasis model assessment index of insulin resistance; HR, heart rate; RER, respiratory exchange ratio; VO_2max, maximal oxygen consumption.
