ABSTRACT
Physical training is an important strategy for the health of people living with HIV/aids; however, its short-term responses have not yet been extensively studied, which limits the understanding of the effects and safety training prescription for this population. Therefore, we aimed to systematically review the acute responses resulting from physical exercise in people with HIV on physiological and immunological variables. For this, a systematic review was carried out from works indexed in the following databases: Medline, Lilacs, Scielo, Web of Science and Science Direct. The keywords used were acquired immunodeficiency syndrome, HIV, AIDS, seropositive, acute session, short, physical activity, exercise, training. The searches were conducted in February 2015 and updated in December 2015 and were conducted without restriction of publication dates or specific language. We included for this review articles that evaluated the acute responses derived from some model of prescription of physical training involving aerobic, weight or combined exercises (aerobic and weight exercises) related to physiological and immunological variables in HIV infected individuals. We found 2,422 titles of which, after exclusion of the duplicates and the application of the eligibility criteria, seven articles were selected for qualitative synthesis. According to the results reported by the studies, there is evidence that immediately after physical exercise an increase in the number of circulating cells occurs, including total leukocytes, neutrophils, monocytes and T CD8+ lymphocytes in HIV-infected people. Furthermore, significant changes in the concentrations of lactate, triglycerides, epinephrine and norepinephrine were also observed immediately after aerobic training regardless the use of HAART and/or hyperlactatemia. However, there is insufficient evidence to state that physical training is totally safe and effective for this population.
