Aerobic capacity

Aerobic capacity refers to the maximum amount of oxygen the body can use during intense exercise, measured in mL/kg/min. It indicates cardiovascular and respiratory efficiency. Higher aerobic capacity enhances endurance, allowing runners to sustain longer efforts. Training methods like long runs and tempo workouts improve this capacity. For example, marathon runners benefit from high aerobic capacity to maintain pace over 26.2 miles. It matters because it directly impacts performance, recovery, and overall fitness. Elite athletes often have high aerobic capacities, while beginners may need targeted training to improve theirs.
