maximal aerobic capacity

Maximal aerobic capacity, often called VO2 max, is the highest amount of oxygen your body can use during intense exercise. It reflects your cardiovascular fitness and how efficiently your heart, lungs, and muscles work together to produce energy. A higher VO2 max indicates better endurance and fitness, enabling you to perform sustained physical activity more effectively. It’s commonly measured in labs through specialized testing, but generally, activities like running, cycling, and swimming can help improve this capacity by challenging your cardiovascular system.
