Does creatine improve cardio?
Aerobic and Anaerobic Energy Pathways
Before we get into whether creatine and aerobic exercise/cardio are a good fit, we need to understand the basics of how the body produces ATP. ATP, or adenosine triphosphate, is the main energy currency in the body. Regardless of whether you eat fats, carbohydrates, or proteins, calories are eventually converted into ATP which directly powers muscle contractions. The body has a few ways to produce ATP depending on how demanding an activity is.
