Aerobic Capacity
Sport Science
Aerobic capacity refers to the total amount of work that can be performed using aerobic metabolism — the body’s oxygen-dependent energy system. It encompasses both VO2 max (the ceiling of oxygen utilization) and the ability to sustain effort at a high percentage of that ceiling over time. An athlete with high aerobic capacity can perform more total work, recover more quickly between high-intensity efforts, and maintain performance quality later in games and training sessions.
What Coaches Should Know
Coaches in power and team sports sometimes undervalue aerobic work on the assumption that their sport is primarily anaerobic — but aerobic metabolism contributes significantly to recovery between high-intensity efforts and to sustaining performance quality across the full duration of a game. Athletes with a weak aerobic base hit a wall later in competition and recover poorly between sessions during high-load training weeks.
Off-season and pre-season aerobic base work — low-to-moderate intensity continuous training, cardiac output sessions, extensive tempo runs — builds the platform that makes high-intensity in-season training sustainable and allows athletes to handle higher training loads without accumulating injury risk.
