Participants in the study, who must have a disease duration shorter than three years, will be randomly assigned to 18 months of treadmill exercise, for 30 minutes four times per week.
This aerobic workout will be done either at high intensity — to keep patients’ heart rates at 80% to 85% of maximum — or at moderate intensity, with a target of 60% to 65% of maximum heart rate.
After the 18 months, patients will be followed for another six months, for a total of two years, to test their ability to sustain exercise independently, according to the press release.
