First seen Jan 05, 2026 · Last updated Apr 28, 2026 · Updated 21 times
Summary
This study looked at how the heart and lungs work in people with Chronic Fatigue Syndrome (ME/CFS) and how that relates to post-exertional malaise (PEM), a severe worsening of symptoms after activity. About 80 participants completed two days of maximal exercise tests, and those with low blood volume received either a saline infusion or a sham treatment before the second test. The goal was to better understand the body's response to exercise in ME/CFS.
