PURPOSE: This study aimed to assess 16-wk improvements of physical fitness, metabolic, and psychological parameters in people living with HIV (PLWH) exercising with the support of asmartphone application, as compared with a control group exercising without application. METHODS: This was a randomized, open-label, pilot study enrolling PLWH in a 16-wk protocol consisting of moderate physical activity three times per week, which included an initial coach-supervised period of 4 wk, followed by 12 wk where participants trained independently. Participants were allocated to either an experimental group that trained using a smartphone application (APP) or a control group that practiced following a hard copy training program (No-APP). At baseline (BL) and after 16 wk (W16), patients were assessed for cardiorespiratory fitness, body composition, blood lipid profile, and POMS. RESULTS:Forty-eight PLWH were screened and 38 were eligible: 20 were allocated to the APP group and 18 to the No-APP group. Two APP and two No-APP participants were lost to follow-up. Intention-to-treat analysis showed a W16 improvement from BL of ≥15% V˙ O2peak in 13 (72%) of 18 in APP, but only in 3 (19%) of 16 in No-APP participants (P = 0.025). Significant W16 improvements were observed in APP, but not in No-APP participants, in V˙O2peak; fat mass and fat-free mass percent; total cholesterol, LDL cholesterol, and triglycerides; vigor; and total mood by POMS. Accordingly, significant percent change differences between the APP and the No-APP groups were observed in V˙O2peak; fat and fat-free mass percent; total cholesterol, LDL cholesterol, and triglycerides; and depression, vigor, anger, and total mood by POMS. CONCLUSIONS: Exercising using a smartphone application improved cardiorespiratory fitness, body composition, cholesterol profiles, and psychological outcomes in PLWH.
