2017.01.17 CSCS Daily Study Question:
When an athlete is exercising, the amount of deoxygenated blood returning to the heart from systemic circulation increases. The increased blood volume returning to the heart causes the end diastolic volume of the heart to be greater than it would when the body is at rest. The increased end diastolic volume causes greater stretch of cardiac myocytes and results in a more forceful contraction causing greater cardiac emptying. Which of the following relates to this principle?
(A) Bohr Effect
(B) Frank-Starling Mechanism
(C) General Adaptation Syndrome
(D) Matveyev’s Model

(B) Frank-Starling Mechanism
The Frank-Starling (pronounced “Frahnk”) mechanism refers to the principle of greater stretch of muscle cells causing a greater force of contraction.
The Bohr Effect refers to oxygen being unloaded by hemoglobin in tissues with higher concentrations of carbon dioxide. Matveyev’s Model refers to periodization training and General Adaptation Syndrome is the model used to describe how the human body reacts to stress (shock/alarm, resistance/adaptation).
