Brief Report: Effects of Low-Volume High-Intensity Interval Training in Hispanic HIV+ Women: A Nonrandomized Study

Background: Low cardiorespiratory fitness (CRF) is usually observed in people living with HIV. The effect of a low-volume high-intensity interval training (LV-HIIT) on CRF in HIV+ and HIV− Hispanic women was evaluated in this study. Setting: A nonrandomized clinical trial with pre-test and post-test using a LV-HIIT intervention was conducted in the AIDS Clinical Trials Unit and the Puerto Rico Clinical and Translational Research Consortium at the University of Puerto Rico Medical Sciences Campus. Methods: Twenty-nine HIV+ and 13 HIV− Hispanic women recruited from community-based programs and clinics, and able to engage in daily physical activities, volunteered to participate. Of these, 20 HIV+ (69%) and 11 HIV− (85%) completed the study and were included in the analyses. LV-HIIT consisted of 6-week, 3 d/wk, 8–10 high-intensity and low-intensity intervals on a cycle ergometer at 80%–90% of heart rate reserve. Main outcome measures were CRF (defined as VO2peak), peak workload, and time to peak exercise. Results: Average peak workload and time to peak exercise increased after training (P
