This study compared how the bodies of ME/CFS patients respond to moderate exercise on a stationary bike. Researchers found that patients who have both ME/CFS and fibromyalgia (a condition causing widespread pain) showed different heart and breathing responses during exercise compared to healthy people, including higher perceived effort and different blood pressure patterns.
