ClinConnect Summary

The COPD-HIIT trial is studying how a new type of exercise called supramaximal high-intensity interval training (HIIT) affects people with Chronic Obstructive Pulmonary Disease (COPD) compared to a more moderate exercise approach. The trial lasts for 12 weeks and will look at how these different exercise methods impact important health areas like brain health, heart fitness, and muscle strength. The researchers are also interested in seeing how these exercise programs compare to usual care over a longer period of 24 months.

To participate in this trial, you need to be at least 60 years old and able to do daily activities on your own. If you have COPD, you should be experiencing symptoms or not exercising regularly at a moderate to high intensity. Healthy individuals with normal lung function can also join as control participants. However, there are some health conditions that would exclude you from participating, such as certain heart or lung diseases. If you decide to join, you can expect to be part of a structured exercise program that aims to improve your overall health and well-being.
