What Is Aerobic Capacity?

Definition
Aerobic capacity is the ability of the body to produce energy through oxygen-dependent processes over extended periods. It underpins endurance, recovery, and repeated-effort performance.

What It Includes
Aerobic capacity involves cardiovascular delivery, mitochondrial function, capillary density, and oxidative enzyme activity. It supports both continuous and intermittent work.

What It Is Not
Aerobic capacity is not synonymous with VO₂max alone. High aerobic capacity does not automatically imply sport-specific endurance or tactical readiness.

Why It Matters
A strong aerobic base improves recovery between efforts, supports higher training volumes, and reduces fatigue accumulation across training and operational demands.

Practical Implications
Aerobic capacity should be developed consistently through appropriately dosed low- and moderate-intensity training rather than relying solely on high-intensity intervals.
