EFFECT OF A SINGLE RESISTANCE EXERCISE SESSION ON INFLAMMATORY MARKERS AND OXIDATIVE STRESS IN WOMEN LIVING WITH HIV

EFEITO DE UMA ÚNICA SESSÃO DE EXERCÍCIO RESISTIDO SOBRE MARCADORES INFLAMATÓRIOS E ESTRESSE OXIDATIVO EM MULHERES VIVENDO COM HIV

ABSTRACT

People living with HIV (PLH), who use antiretroviral therapy (ART), are more susceptible to changes in the inflammatory profile and oxidative stress, and women have greater access to ART. Although physical exercise is a complementary strategy to treatment due to its antioxidant and anti-inflammatory effects, it is not clear whether acute responses to exercise can be harmful to PLH. The aim of the study was to investigate the acute effect of resistance exercise (RE) on inflammatory and oxidative stress markers in PLH. Ten women, using ART, performed RE session consisting of seven exercises for the whole body. For biochemical evaluation, blood samples were collected before (pre), 1 hour (1h) and 2 hours (2h) after the RE session. One-way ANOVA followed by Bonferroni's post hoc test was used to compare results between time points. There was an increase only in markers, GSSG of 160% (pre: 0.40 ± 0.11; 1h: 1.18 ± 0.36; 2h: 1.04 ± 0.25 mmol/g), TNF-α of 98 % (pre: 4.60 ± 0.55; 1h: 6.95 ± 0.77; 2h: 9.10 ± 1.03 pg/ml) and 52% IL-6 (pre: 2.47 ± 0 .67; 1h: 3.63 ± 1.26; 2h: 5.38 ± 2.15 pg/ml). The other variables remained unchanged (P > 0.05). It is concluded that a RE session increased the levels of inflammatory markers and oxidative stress in PLH in a non-exacerbated way.
