Physical Education
In the above section you have learnt about the components of physical fitness. and Sports Sciences
Now in the next section you will learn the exercises you can use to train above
mentioned components.

14.3 AEROBIC AND ANAEROBIC EXERCISES

It is often said that exercises cannot be performed without oxygen. To some
extent it is true. When exercises are performed for the longer period of time,
constant supply of oxygen is required. Whereas certain exercises are performed Note
as ballistics movement or separated in shorter span of time. Such activities do
not require constant supply of oxygen. Basic difference in aerobic and anaerobic
can be understood by discussing further about aerobic and anaerobic exercises.

Aerobic Exercise
Aerobic exercises are the exercises which are performed with the oxygen and
glucose and fat used as fuel. Aerobic activities can be sustained for a longer
period of time. Some of aerobic activities are slow and continuous running or
jogging.

Anaerobic Exercise

Anaerobic exercises are performed where the constant supply of oxygen is not
present. Examples of anaerobic exercises are short distance running like 100
meters. While performing anaerobic exercise our body generates lactic acid which
causes fatigue at sustained levels term.

Differences in Aerobic and Anaerobic Exercises

Aerobic exercise Anaerobic exercise

Involves oxygen in energy production Doesn’t involve oxygen in energy
production
May last longer than 2 minutes Lasts from a few seconds to 2
minutes, then a pause is
required

Increases endurance, improves Increases strength, improves bone
cardiovascular system density, builds up muscles

14.3.2 Process of Determining Aerobic or Anaerobic Fitness

For determining the kind of exercise you are performing, you can use your
maximum heart rate (MHR) to calculate which exercise you are performing.
