Exercise Terms You Should Know

Fitness danceAerobic Exercise: An exercise that uses oxygen for energy production. It is more efficient and generates fewer waste products as compared to the anaerobic exercise. When we use the term aerobic exercise, we usually mean — sustained or continuous exercise of major muscles of the body.

Anaerobic Exercise: When we begin to exercise, initial energy is
provided by the blood, which is present in the muscles. As this blood is not rich in oxygen, the energy production is not efficient and plenty of waste products are generated.

Anaerobic mechanism comes into play when we require short bursts of energy, e.g. when we run to catch the bus.

Fitness: It  refers to — how efficiently the oxygen is extracted and
transported from blood to the muscles. The more efficient this mechanism is more is the level of fitness. Measures of fitness are:

1. How long it takes for the pulse rate to return to normal after exercise.

2. What is the resting pulse — the slower is the resting pulse, the more fit a person is.

3. How far and how long can one exercise?

Warm-up: This is the first stage of an exercise schedule; a preparatory phase of 5-10 minutes. During warm-up, muscles gradually shift from anaerobic mechanism to aerobic mechanism. The main benefit of warm-up is that there is less tiredness and risk of exercise-induced injury is also reduced.

Cool-down: The last stage of an exercise schedule. It is also of
10-15 minutes. During cool-down, the heart and blood vessels gradually come back to normal state. The main benefit of cool-down is that there is less muscle ache and the risk of giddiness, which is sometimes felt after severe exercise, is reduced.
