Individuals with post-acute sequelae of SARS-CoV-2 infection (PASC) and myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) commonly experience post-exertional malaise following an exercise task.
This study examined tolerance to a tailored low-to-moderate intensity exercise task using age-predicted maximal heart rate guided by symptom-based intensity modifications in individuals with PASC and ME/CFS.
Thirty individuals with PASC, ME/CFS, and controls completed a bout of whole-body exercise on an upright cycle ergometer for 25-minutes.
Aspects of post-exertional malaise, specifically pain and fatigue were assessed prior to, during, and up to 7-days following the exercise bout using 0-10 numerical rating scales.
Individuals with PASC and ME/CFS achieved similar target heart rates (118.6±13.3bpm), and changes in perceived exertion (3.8±1.9), fatigue (2.0±1.9), and pain (1.1±1.5) during the 25-minute exercise task.
Controls performed the bicycle task with greater revolutions per minute (p<.001) without significant increases in pain or fatigue.
Changes in perceived physical fatigue (p<.001), mental fatigue (p<.001), and pain (p<.012) differed by group during the 7-days following exercise with PASC and ME/CFS.
The greatest increases in pain (ME/CFS:+1.0, PASC:+0.3), physical fatigue (ME/CFS:+1.2, PASC:+0.7) and mental fatigue (ME/CFS:+1.2, PASC:+0.6) occurred on day 1 and returned to baseline within 7 days.
This study demonstrates the impact of an individualized, low-to-moderate exercise task on post-exertional symptoms of pain and fatigue in individuals with PASC and ME/CFS.
Further investigation will address the individual variability in symptom responses and the impact of repeated exercise bouts in larger cohorts.
