[Effects of physical exercise in a population with systemic lupus erythematosus: A systematic review].

This systematic review was aimed at analysing the existing scientific evidence regarding the effects of physical exercise on the symptomatology, disease activity, and fitness level in a population with systemic lupus erythematosus. Following the PRISMA checklist, a search was carried out on PubMed, PEDro, and Sportdiscus databases. The PEDro and MINORS checklists were used in order to identify the methodological quality of the studies selected. A total of 14 studies were found, of which 10 were randomised controlled trials, and 4 were comparative studies. The performance of physical exercise led to significant improvements in fitness and fatigue. No adverse effects were registered. None of the studies found reported positive effects on the disease activity. The obtained results imply that the performance of physical exercise is safe for people with systemic lupus erythematosus, although its benefits are reduced mainly to improvements in their fitness and perceived level of fatigue.
