NCT ID NCT07454395
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This pilot study looks at whether light, self-paced swimming is a tolerable activity for people with ME/CFS and related conditions like Long COVID and fibromyalgia. Participants will swim for 15-30 minutes at their own pace and track symptoms and heart rate variability using an app. The goal is to see if swimming causes less post-exertional malaise than cycling, due to the supportive effects of water immersion.
