Many people say it's hard to work out after a bout of Covid-19 and these setbacks go beyond the usual struggles that follow physical illness, according to a study published Wednesday.
Difficulty exercising can be added to the list of Covid symptoms, according to an analysis of nine studies.
The phenomenon of deconditioning can not account for all of the findings of the studies.
Other factors that could contribute to the exercise difficulties faced by people with long Covid were noted by the researchers.
Studies show that people with long Covid have lower peak levels of oxygen when exercising in a laboratory.
A professor of medicine at the University of California, San Francisco and one of the study's authors, said the drop translated to a woman aged 40 with long Covid having the expected exercise capacity of a 50 year old woman without the condition.
The findings are averaged and each person will experience different drops in exercise capacity if they switch from doubles tennis to stretching exercises or playing golf with a cart.
The study found a modest but consistent trend in the number of people with long Covid who experience a drop in exercise tolerance. The quality of evidence is poor due to the small sample sizes of most studies, which leaves results open to bias.
Our understanding of long Covid is poor. According to the WHO, between 10% and 20% of Covid survivors are affected by it. There are no proven treatments for the syndrome and experts don't know what the underlying causes are. Women are more likely to be hospitalized with Long Covid than men. The impact of Covid is having on millions of people around the world as well as imposing a heavy economic burden that could delay our recovery from the Pandemic.
A study found that women and hospitalized patients are more likely to have long covidies.
