Summary
This study looked at how different types of aerobic exercise (moderate continuous training vs. high-intensity interval training) and diet counseling affect cell health in people with type 2 diabetes. Researchers measured changes in mitochondria (the cell's power plants) and oxidative stress (cell damage) in 146 participants over 12 weeks. The goal was to find the best combination of exercise and diet for improving cell function and overall health.
