Strength training with blood flow restriction in HIV patients positive: a case study
Keywords:muscle strength, acquired immune deficiency syndrome, HIV-1, exercise, Kinanthropometry
This study purposed to compare responses of segmented neutrophils, monocytes,
lymphocytes, and T lymphocyte Clusters of Differentiation 4 and 8 (CD4+ T and
CD8+ T) to blood flow restriction training in HIV patients. Two HIV patients
participated in the study, one patient had a sedentary lifestyle, and the other was
physically active. HIV-infected female patients performed a blood flow restriction
training session consisting of two exercises: flat bench press and knee extension.
Blood (6 mL) was collected for analysis prior to training, immediately after
training, and 30 minutes after. After blood flow restriction training, percentage
changes in the number of leukocytes were observed in both patients. Monocytes
showed different responses in the two patients: a decrease in monocyte count was
seen in the physically active, and an increase was observed in the sedentary
lifestyle. Lymphocytes showed a higher increase in the physically active than in the
sedentary lifestyle. There was an increase in the CD4+ / CD8+ T lymphocyte ratio
in both patients. It was concluded blood flow restriction promoted acute
inflammation after training, shown by changes in immune cell counts. These
changes did not promote immunosuppression; instead, an increase in CD4+/CD8+
T lymphocyte ratio was observed; and HIV-infected came similar results.
