Aerobic vs. Anaerobic Physical Activities

There are two sides to total fitness:

cardiorespiratory fitness

anaerobic fitness

5

Aerobic vs. Anaerobic Physical ActivitiesAerobic activity must occur over a sustained period of time; anaerobic activity works differently.

Anaerobic activity

Activity that requires high

levels of energy and is done for

only a few seconds or minutes at a

high level of intensity.

Term to Know

6

Aerobic vs. Anaerobic Physical Activities

Anaerobic means “without oxygen.”

The energy produced in anaerobic activities does not depend on oxygen.

7

Aerobic vs. Anaerobic Physical ActivitiesParticipation in anaerobic activities leads to anaerobic fitness.

anaerobic fitness

Higher levels of muscular strength,

muscular endurance, and

flexibility.

Term to Know

8

Aerobic vs. Anaerobic Physical Activities

Anaerobic activities require large amounts of energy, a requirement that your body cannot meet for very long.

This is because your heart cannot supply enough oxygen-rich blood to your tissues and organs to meet the high demand.

9

Aerobic vs. Anaerobic Physical Activities

When you can meet your energy needs by supplying large amounts of oxygen to your body, you are working primarily in an aerobic mode.

If you cannot meet the oxygen demands of a high-intensity physical activity, your body is more conditioned to working anaerobically.

10

Aerobic vs. Anaerobic Physical ActivitiesInterval training can allow you to work aerobically and anaerobically in the same workout.

Interval training

A program in which high-intensity

physical activities alternate with low-intensity recovery bouts for several minutes at a time.
