A study from Vrije Universiteit Amsterdam, published in Nature Communications, has found that people with long Covid experience severe muscle damage, mitochondrial problems, and the presence of microclots, leading to debilitating symptoms after exercise. The research involved 25 long Covid patients and 21 recovered individuals, revealing that those with long Covid had a lower exercise capacity, more white muscle fibers with fewer mitochondria and capillaries, and significant tissue damage post-exercise. The findings suggest that intense exercise can exacerbate symptoms and that treatments improving mitochondrial health could be beneficial.
