Summary
This study compares two methods of prescribing high-intensity interval training (HIIT) for people in cardiac rehabilitation. Thirty adults with heart conditions will follow a 12-week exercise program to see which prescription approach improves fitness, heart function, and oxygen use better. The goal is to find the most effective way to help heart patients recover through exercise.
