the Effect of Fasted Versus Post-meal HIIT on Glycemic Control in Men With Type 2 Diabetes Mellitus

The subjects in the four groups performed 12 weeks of supervised HIIE program on a motorized treadmill (h/p/cosmos, Pulsar 4.0, Nussdorf-Traunstein, Germany) with a rate of three sessions weekly. The session commenced with a 5 min warming-up and concluded with a 5 min cooling down period. The exercise effort component consisted of 5 intervals of HIIT. Each interval continues for four min of HIIT with exercise intensity ranging from 75% to 90% of the peak heart rate. Each active recovery period between exercise intervals included moderate exercise at intensity of 50% to 60% of the peak heart rate. Every 3 weeks, the exercise intensity was increased by 5% starting with 75% of the HRmax in the first 3 weeks, 80% in the following 3 weeks and progressed to 90% the HRmax in the last 3 weeks. The subject's heart rate throughout the HIIT session was monitored using a polar heart rate monitor (Polar, Kempele, Finland).
