Aerobic capacity is the ability of your body to take in, transport, and use oxygen during sustained physical activity.
It reflects how efficiently your heart, lungs, and muscles work together to support endurance performance.
The higher your aerobic capacity, the more oxygen you can deliver to your muscles during exercise.
This capacity is essential for cyclists, as it determines how long you can maintain efforts without fatiguing.
Aerobic capacity is closely related to VO2Max, although they are not exactly the same.
Training at low to moderate intensity improves aerobic capacity over time.
Rides in heart rate Zone 2 are especially effective for developing this system.
Improving aerobic capacity enhances fat metabolism, cardiovascular function, and muscular endurance.
It also builds the foundation for higher-intensity training in later phases.
Understanding aerobic capacity helps you structure your training for long-term endurance and consistent performance.
