Effects of an Indoor Cycling Program on Cardio-Metabolic Factors in Women With Obesity and Normal Body Weight

"The 3-month intervention consisted of a physical exercise program involving three indoor cycling sessions per week, with a total of 36 training sessions. Subjects exercised on cycle ergometers Schwinn® Evolution® (Schwinn Bicycle Company, Boulder, Colorado, USA). Each session lasted approximately 55 minutes. Training sessions consisted of a 5-min low-intensity warm-up (cycling at 50-65% of maximum heart rate (HRmax)), 40 min of main training at an intensity of 65-95% of HRmax, 5 min of non-weight-bearing cycling, finishing with 5 min of low-intensity cool-down stretching and breathing exercises.~Main part of the training was interval. Each exercise session consisted of 3 to 4 high intensity intervals with intensity exceeding 80% of HRmax, often reaching anaerobic threshold. High intensity intervals lasted approximately 4-minutes and were interspersed by recovery periods at 65-80% of HRmax."
