ABSTRACT

O objetivo do presente estudo foi avaliar os efeitos do treinamento físico combinado (TC) de 16 semanas sobre a composição corporal e o sistema imune, bem como velocidade e inclinação da esteira rolante obtidos na intensidade do limiar anaeróbio (LAn) em indivíduos com HIV. Participaram do estudo10 indivíduos, sendo 5 homens e 5 mulheres (44,7±8,97 anos; Tempo de Terapia Antirretroviral Altamente Ativa [HAART]: 8,89±6,21 anos; Tempo Portador: 9,14±5,37 anos; Carga Viral: indetectável), os quais foram submetidos a 16 semanas de TC. Os dados foram expressos como média±desvio padrão (p≤0,05). Foram observadas melhoras em relação à massa magra relativa (MMR; %) (Pré: 45,5 [32,8 – 63,0]; Pós: 47,9 [33,7 – 66,3]) e massa magra absoluta (MMA; %) (Pré: 67,0 [55,0 – 75,2]; Pós: 68,8 [56,6 – 75,7]). O índice de massa corporal (IMC; kg/m2 ) não sofreu alteração pós TC (Pré: 24,2 [21,3 – 28,7]; Pós: 23,7 [21,8 – 30,0]). A carga viral permaneceu indetectável, sendo que houve aumento no número delinfócitos T CD4+ (Pré: 529 [426,0 – 900,0]; Pós: 694 [381,0 – 1175,0]). Além disso, houve melhora nosvalores de VO2 (ml.kg.min-1) (Pré: 16,2±4,9; Pós: 21,2±3,2), velocidade (km/h) (Pré: 5,7±0,9; Pós: 6,3±1,0) e inclinação (%) (Pré: 3,8±1,2; Pós: 4,9±1,0) obtidos na intensidade do LAn. Conclui-se que oTC melhorou o VO2 na intensidade do LAn e induziu a aumentos de MMR e de MMA. Finalmente, o TC promoveu aumento no número de linfócitos T CD4+, sem efeito negativo sobre a carga viral. Estes resultados são de extrema importância para a qualidade de vida dos pacientes com HIV.


The aim of the present study was to evaluate the effects of combined physical training (CT) on body composition and immune system, as well as, speed and inclination obtained at the intensity of anaerobic threshold (AT) in subjects with HIV. Ten individuals, 5 men and 5 women, united in a single group (44.7±8.97 years of age; Highly Active Antiretroviral Therapy [HAART] time: 8.89±6.21 years; HIV-Bearer Time: 9.14±5.37 years; Viral Load: undetectable), were subjected to 16 weeks of CT. Data were expressed as mean±standard deviation (p ≤ 0.05). Both relative lean mass (RLM; %) (Pre: 45.5 [32.8-63.0]; Post: 47.9 [33.7-66.3]) and absolute lean mass (ALM; %) (Pre: 67.0[55.0-75.2]; Post: 68.8 [56.6-75.7]) were improved after CT. The body mass index (BMI; kg/m2 ) did not change post-CT (Pre: 24.2 [21.3 – 28.7]; Post: 23.7 [21.8 – 30.0]). The viral load remained undetectable, while the number of CD4+ T lymphocytes was increased (Pre: 529 [426.0-900.0]; Post: 694 [381.0-1175.0]). In addition, VO2(ml.kg.min-1) (Pre: 16.2 ± 4.9; Post: 21.2 ± 3.2), speed (km/h) (Pre: 5.7 ± 0.9; Post: 6.3 ± 1.0) and inclination (%) (Pre: 3.8 ± 1.2; Post: 4.9 ± 1.0), obtained at AT intensity, were improved. It was concluded that CT was able to improve the VO2 at the intensity of AT and induced increases in RLM and ALM. Finally, the CT increased the number of CD4 + T lymphocytes, with no negative effect on the viralload. These results are extremely important for the quality of life of patients with HIV.
