Physiology of Training Part 1

Flashcards on Physiology of Training

Progressive Overload

An organ system or tissue must be exercised at a level beyond which it is accustomed to achieve a training adaptation.

Specificity

Training adaptations are highly specific to the type of activity being performed and the volume and intensity of the exercise.

Reversibility

Fitness gains from exercising are quickly lost when training stops; physiological adaptations will be reversed.

V̇O2max Increases with Training

A 2 to 3 month training program typically results in a 15–20% increase in V̇O2max.

Genetics and V̇O2max

Heritability determines 50% of V̇O2max in untrained subjects and plays a significant role in how individuals respond to training.

Cardiac Contractility

Strength of cardiac muscle contraction when EDV, afterload, and HR remain constant.

Endurance Training and Afterload

Endurance training results in a decrease in afterload.

Maximal cardiac output

One of the factors contributing to training-induced increases in VO2max.

a-v 02 difference

One of the factors contributing to training-induced increases in VO2max.

Stroke volume

One of the factors contributing to training-induced increases in VO2max.

Muscle blood flow

One of the factors contributing to training-induced increases in VO2max.

Capillaries

One of the factors contributing to training-induced increases in VO2max.

Mitochondria

One of the factors contributing to training-induced increases in VO2max.
