Optimizing Aerobic Fitness and Functional Response to Exercise in Older Adults

What this Trial Is About

Cardiovascular disease often leads to hospitalization and disability in older adults. This research aims to improve recovery of aerobic fitness and physical function in older cardiac patients by comparing a new high intensity training program with the traditional moderate intensity cardiac rehabilitation exercises. The study focuses on older adults who have experienced recent heart events like myocardial infarction or percutaneous interventions, seeking better ways to reduce disability and improve health outcomes. Participants will be randomly assigned to one of two exercise programs: a combined high intensity interval aerobic training (HIIT) with high intensity resistance training (HIRT), or the usual moderate intensity continuous aerobic training (MICT) with moderate intensity resistance training (MIRT) used in cardiac rehabilitation. Both approaches are performed during Phase 2 cardiac rehabilitation following hospitalization. The study compares these two regimens to see which better improves aerobic capacity and physical function. During the study, participants’ aerobic fitness and physical function will be measured within four months after starting the exercise program. Tests include the 30-second sit-to-stand test and assessments of quality of life, depressive symptoms, executive function, physical function through a six-minute walk test, enjoyment of exercise, and anxiety. The study involves regular monitoring and safety assessments throughout to evaluate the effects of the training on participants’ recovery and functional abilities.
