The ME\/CFS group showed high self-report fatigue and impaired physical function, whereas healthy controls did not show fatigue or function abnormalities.<\/p>\n<p>In patients, no significant post-exercise changes were found for heart rate variability (HRV); however, heart rate decreased in ME\/CFS males from Day 14 to Day 15 (p\u2009=\u20090.046). Female patients showed increased fatigue (p\u2009=\u20090.006) after the initial walk test, but a downward slope (p\u2009=\u20090.008) in fatigue following the second walk test.
