CPSS Foundations of Exercise Science 5

Question 1

Which principle of training states that adaptations are specific to the type, intensity, and mode of exercise performed?

Accepted Answer

SAID principle (Specific Adaptation to Imposed Demands)

Answer

The SAID principle dictates that the body adapts specifically to the demands placed on it, so training must mimic the sport or performance goal.

Question 2

The primary function of the Golgi tendon organ (GTO) is to:

Accepted Answer

Sense tension within the tendon and inhibit excessive muscle force

Answer

GTOs are mechanoreceptors at the musculotendinous junction that monitor muscle tension and trigger autogenic inhibition to protect against excessive force.

Question 3

What does the term 'ventilatory threshold 2' (VT2) physiologically correspond to?

Accepted Answer

The intensity where ventilation increases disproportionately due to excess CO2 buffering of bicarbonate

Answer

VT2 (also called the respiratory compensation point) occurs when hyperventilation accelerates to buffer rising H+ via bicarbonate, producing a second steep rise in VE/VCO2.

Question 4

Which of the following is a primary chronic cardiovascular adaptation to endurance training?

Accepted Answer

Cardiac hypertrophy (eccentric) with increased left ventricular end-diastolic volume

Answer

Endurance training induces eccentric left ventricular hypertrophy, increasing chamber volume and stroke volume, which contributes to athlete's bradycardia.

Question 5

In biomechanics, the 'stretch-shortening cycle' (SSC) refers to:

Accepted Answer

The sequential eccentric loading followed by rapid concentric contraction that enhances power output

Answer

The SSC involves a rapid eccentric pre-stretch that stores elastic energy and potentiates muscle activation, enhancing subsequent concentric force and power production.
