Official title

Sex Differences in Exercise-related Post-exertional Malaise in ME/CFS

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This pilot study is intended to identify sex differences in myalgic encephalomyelitis/ chronic fatigue syndrome (ME/CFS) during recovery from brief but high effort exercise tests. It is expected that women with ME/CFS as compared to males with ME/CFS will show slower recovery from exercise with respect to heart rate and blood pressure, physical functioning, and symptom severity. Also females with ME/CFS as compared to males with ME/CFS will show greater negative impacts on heart rate, blood pressure, physical functioning and symptom severity after the two exercise tests. The findings will have implications for sex differences in the pathophysiology of post-exertional malaise and activity/exercise self-management recommendations, given the expected detrimental effects of the brief intense exercise tests on patients with ME/CFS.
