CPSS Foundational Scientific Disciplines 5

Question 1

Which organ is the primary site of gluconeogenesis during prolonged fasting or endurance exercise?

Accepted Answer

Liver

Answer

The liver is the dominant gluconeogenic organ, synthesizing glucose from lactate, amino acids, and glycerol to maintain blood glucose homeostasis during prolonged exercise.

Question 2

According to Newton's second law applied to sport, doubling an athlete's acceleration while keeping mass constant will:

Accepted Answer

Double the net force required

Answer

Newton's second law (F = ma) shows that force is directly proportional to acceleration; doubling acceleration while mass stays constant doubles the required net force.

Question 3

The term 'periodization' in sport science refers to:

Accepted Answer

Systematic variation of training load and volume over time to optimize performance

Answer

Periodization is the planned manipulation of training variables (volume, intensity, frequency) across time blocks (microcycles, mesocycles, macrocycles) to maximize performance at target competitions.

Question 4

Which type of measurement scale has a true zero point and allows meaningful ratio comparisons?

Accepted Answer

Ratio scale

Answer

Ratio scales have all properties of interval scales plus an absolute zero, allowing statements like 'twice as much' (e.g., force in Newtons, VO2 in mL/kg/min).

Question 5

Excess post-exercise oxygen consumption (EPOC) is primarily caused by:

Accepted Answer

Elevated metabolism needed for restoration of homeostasis after exercise

Answer

EPOC reflects the elevated oxygen consumption during recovery that supports ATP/PCr resynthesis, lactate clearance, temperature normalization, catecholamine metabolism, and protein synthesis.
