There are 5 names in this directory beginning with the letter A.
Aerobic
Meaning "with Oxygen", used to refer to exercise at low enough intensity that cardiovascular systems can deliver Oxygen required by muscles and lactic acid doesn't build up in muscles. Aerobic pace should be sustainable for very long periods of time.

Aerobic Capacity
The maximum amount of oxygen that can be utilized by the body, also called VO2max.

Anaerobic
Meaning "without Oxygen", used to refer to higher intensity exercise that cannot be maintained for very long because muscles are not getting needed Oxygen and will build up lactic acid.

Anaerobic Capacity
The maximum amount of energy that can be produced without requiring oxygen.

Anaerobic Threshold (AT)
The line between aerobic and anaerobic running. Good training will increase this threshold by teaching the muscles to use oxygen more efficiently, so that less lactic acid is produced.
