Improving aerobic fitness in older adults with heart conditions

Optimizing Aerobic Fitness and Functional Response to Exercise in Older Adults

Not applicable Interventional University of Vermont Medical Center · NCT06951620

This study is testing whether a new exercise program that combines high-intensity workouts can help older adults with heart conditions get fitter and feel better compared to a more moderate exercise routine.

What this trial studies

This study aims to enhance aerobic fitness and physical function in older adults with cardiovascular disease by comparing two exercise regimens: high intensity interval training (HIIT) combined with high intensity resistance training (HIRT) versus moderate intensity continuous training (MICT) combined with moderate intensity resistance training (MIRT). The research focuses on older cardiac patients who often experience limited benefits from traditional rehabilitation methods. By addressing the unique needs of this population, the study seeks to optimize recovery and improve clinical outcomes. The primary goals are to assess the effectiveness of each training approach in increasing VO2peak and physical function.

Who should consider this trial

Good fit: Ideal candidates are older adults over 65 years old who are ambulatory and enrolled in cardiac rehabilitation following a recent myocardial infarction or percutaneous intervention.

Not a fit: Patients with active malignancies or those unable to comply with the prescribed exercise regimen may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could significantly improve the recovery and quality of life for older adults recovering from cardiac events.

How similar studies have performed: Previous studies have shown that high intensity interval training can be more effective than moderate intensity training in improving aerobic fitness, suggesting potential success for this approach.
