Quick Summary
This study created practical guidelines for exercise training in people with long COVID, especially those who experience post-exertional malaise (PEM)—when symptoms get worse after physical activity. The researchers reviewed 46 previous studies and surveyed 14 international experts to develop three different exercise approaches depending on whether someone has no PEM, mild/moderate PEM, or severe PEM. These guidelines aim to help healthcare professionals safely design exercise programs tailored to each person's specific situation.
Why It Matters
For ME/CFS patients, post-exertional malaise is a defining and debilitating feature that makes standard exercise recommendations potentially harmful. This guideline specifically addresses PEM severity as a stratifying factor, filling a critical clinical gap and providing healthcare providers with structured, evidence-informed approaches to exercise prescription that prioritize safety and individual tolerance.
Observed Findings
46 trials on exercise training in long COVID were identified from January 2020 to January 2024.
Exercise training regimens across studies were highly heterogeneous in protocol design and implementation.
No included studies reported or addressed management of post-exertional malaise within an exercise training program.
14 international experts in exercise training and long COVID provided survey feedback to inform recommendations.
Inferred Conclusions
Post-exertional malaise represents a significant barrier to standard exercise training in long COVID and requires differentiated clinical approaches.
Exercise training recommendations should be stratified according to PEM presence and severity (none, mild/moderate, severe).
A consensus-based best practice framework may guide allied healthcare professionals in safely initiating and adjusting personalized exercise programs until rigorous trial evidence emerges.
Remaining Questions
What are the optimal exercise protocols (intensity, duration, modality, progression rate) for each PEM severity stratum, and are these recommendations similarly applicable to ME/CFS?
How should exercise programs be monitored and adjusted in real time when patients experience PEM symptoms during or after training?
What This Study Does Not Prove
This study does not prove that the proposed exercise protocols are effective at improving outcomes—it is a consensus guideline based on expert opinion and heterogeneous literature, not a clinical trial demonstrating efficacy. It does not establish which specific exercise modality or intensity is optimal for any PEM severity category, nor does it provide quantitative outcome data validating the stratification approach.
