In silico analysis of exercise intolerance in myalgic encephalomyelitis/chronic fatigue syndrome.
Lengert, Nicor, Drossel, Barbara·Biophysical chemistry·2015
This study used computer models to understand why people with ME/CFS struggle with exercise. The researchers simulated what happens in muscle cells during and after physical activity, focusing on mitochondria—the parts of cells that produce energy. Their model showed that when mitochondrial function is reduced, muscles can't make enough energy (ATP), which causes them to accumulate toxic substances like lactate and acid, and can lead to cell death. Importantly, repeated exercise made this problem much worse in their simulations.
