Aerobic Capacity vs Work Capacity

Core Difference
Aerobic capacity reflects long-duration oxygen-based energy production, while work capacity reflects the ability to perform and recover from repeated work.

Aerobic Capacity Focus
Aerobic capacity supports recovery, endurance, and fatigue resistance.

Work Capacity Focus
Work capacity emphasizes output density, repeated effort tolerance, and recovery speed.

Why the Difference Matters
High work capacity without aerobic support often leads to rapid fatigue accumulation.

Key Takeaway
Aerobic capacity underpins sustainable work capacity.
