Is there evidence that physical activity benefits people with HIV infection?
18 publications were reviewed to evaluate physical activity for people with HIV infection. Two recent systematic Cochrane reviews conclude that performing constant or interval aerobic exercise, progressive resistance exercise, or a combination of both, for at least 20 minutes per session at a frequency of three times per week is generally safe in adults with HIV infection and may lead to significant improvements in strength, endurance, cardiopulmonary fitness and reductions in depressive symptoms. Studies published since that time support those findings, however, research on the relationship between physical activity and immunity in people with HIV is inconclusive. Special considerations may be needed for people with HIV infection who have reduced aerobic capacity, metabolic changes, increased pain, fatigue and impairments while exercising and those with a history of drug and alcohol abuse. Further research is needed on the effect of physical activity on serum lipid profile in people with HIV infection.
- Grade I means there is Good/Strong evidence supporting the statement;
- Grade II is Fair;
- Grade III is Limited/Weak;
- Grade IV is Expert Opinion Only;
- Grade V is Not Assignable.
- High (A) means we are very confident that the true effect lies close to that of the estimate of the effect;
- Moderate (B) means we are moderately confident in the effect estimate;
- Low (C) means our confidence in the effect estimate is limited;
- Very Low (D) means we have very little confidence in the effect estimate.
- Ungraded means a grade is not assignable.
