NCT05965518 · Status: RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 60

Summary

This is a single site, randomized exercise trial with individuals at least 50 years of age living with HIV who experience suboptimal cognition. The overall goals of this proposal are to determine whether 16 weeks of structured high-intensity interval training (HIIT) can overcome vascular and cognitive impairments (Aim 1) to a greater extent than continuous moderate exercise. Additionally, investigator will seek to identify barriers to engagement in exercise and the participants' perceptions of the study and exercise interventions (Aim 2). This study will enroll 60 participants in Birmingham, Alabama. Data collection will occur at each visit, with baseline data collected at the initial visit with a 3-month follow-up occurring following completion of the intervention.

Conditions

  • HIV
  • Arterial Stiffness
  • Cognitive Dysfunction

Interventions

BEHAVIORAL

High-Intensity Interval Training

Following a 5-minute warm-up at 50% VO2peak, high and moderate-intensity exercise bouts alternate, progressing to five bouts of 4-minute high-intensity exercise (90% VO2peak), alternating with four 3-minute bouts of moderate-intensity exercise (50% VO2peak) by week 8, followed by a 5 minute cool-down. The total exercise time is 42 minutes.

BEHAVIORAL

Continuous Moderate Exercise

Following a 4 minute warm-up at 50% VO2peak, the participant walks for up to 42 continuous minutes at 60% VO2peak, followed by a 4 minute cool-down. The total exercise time is 50 minutes.
