Many people with long Covid feel tired, unwell and in pain for lengthy periods after exercise, and researchers say they now know why.

Experts say they have evidence that biological changes are to blame, such as severe muscle damage, mitochondrial problems and the presence of microclots in the body.

“It’s really confirming that there is something inside the body going wrong with the disease,” said Dr Rob Wüst, an author of the study at Vrije Universiteit (Free University) Amsterdam.

Long Covid is thought to affect tens of thousands of people in the UK alone, and many experience a worsening of symptoms for weeks after a single bout of exercise.

Hannah Davis misses her old self. Like so many people around the world, she has seen her life upended by long COVID, which has made many once-routine activities impossible. The 32-year-old has stopped working at her job in the field of machine learning and generative models. It’s too cognitively taxing; the lights from display monitors are disorienting. Merely standing up from a sitting position causes her heart rate to shoot to 170 beats per minute, the equivalent of doing a good jog.

SARS-CoV-2 can cause lasting damage to cells’ energy production

At the beginning of the COVID-19 pandemic, the virus responsible for the disease, SARS-CoV-2, was feared for its devastating damage to the lungs. But it quickly became apparent that the virus can infect organs and tissues throughout the body, including the heart, brain, kidneys, and blood vessels.

Much of the resulting dysfunction was thought to be the result of inflammation, the immune system’s response to infection. But research has suggested that effects on mitochondria may also play a role in organ damage from SARS-CoV-2 infection. Mitochondria are the powerhouses of cells, producing most of the energy they need.

This study provides us with strong evidence that we need to stop looking at COVID-19 as strictly an upper respiratory disease and start viewing it as a systemic disorder that impacts multiple organs. The continued dysfunction we observed in organs other than the lungs suggests that mitochondrial dysfunction could be causing long-term damage to the internal organs of these patients.
