Aerobic Exercise Principles Flashcards

Vocabulary flashcards for review.

Fitness

A general term used to describe the ability to perform physical work.

Maximal Oxygen Consumption (VO2 max)

A measure of the body's capacity to use oxygen; the maximum amount of oxygen consumed per minute when the individual has reached maximal effort.

Endurance

The ability to work for prolonged periods of time and the ability to resist fatigue.

Muscular endurance

The ability of an isolated muscle group to perform repeated contractions over a period of time

Cardiovascular endurance

The ability to perform large muscle dynamic exercise for long periods of time

Aerobic Exercise Training (Conditioning)

The augmentation of the energy capacity of the muscle by means of an exercise program.

Adaptation

Results in increased efficiency of the cardiovascular system and the active muscles; represents a variety of neurologic, physical, and biochemical changes within the cardiovascular and muscular system.

Myocardial Oxygen Consumption (mVO2)

A measure of the oxygen consumed by the myocardial muscle.

Deconditioning

Occurs with prolonged bed rest and is seen in patients who have had an extended illness

Kilocalorie

Measure expressing the energy value of food

MET (metabolic equivalent)

Defined as the oxygen consumed (milliliters) per kilogram of body weight per minute; used to estimate the metabolic cost (oxygen consumption) of physical activity.

Exercise pressor response

Sympathetic nervous system (SNS) response resulting in the stimulation of small myelinated and unmyelinated nerve fibers in skeletal muscle.

Overload Principle

Stress on an organism that is greater than the one regularly encountered during everyday life.

Specificity Principle

Refers to adaptations in metabolic and physiologic systems depending on the demand imposed.

Reversibility Principle

The beneficial effects of exercise training are transient and reversible.
