Question 1

Creatine supplementation is MOST effective for improving performance in which type of activity?

Accepted Answer

Repeated high-intensity bouts with short recovery periods

Answer

Creatine enhances phosphocreatine resynthesis, improving repeated high-intensity, short-duration performance such as sprints, heavy lifts, and interval sports.

Question 2

Which ergogenic aid has the MOST consistent scientific evidence supporting performance enhancement across a wide range of sports?

Accepted Answer

Creatine monohydrate

Answer

Creatine monohydrate has the largest and most consistent evidence base of any legal ergogenic supplement, improving power, strength, and high-intensity exercise capacity.

Question 3

Caffeine enhances athletic performance primarily through which physiological mechanism?

Accepted Answer

Blocking adenosine receptors in the central nervous system

Answer

Caffeine primarily blocks adenosine receptors in the central nervous system, reducing perceived exertion and delaying the onset of fatigue.

Question 4

Iron deficiency anemia would most adversely affect which aspect of athletic performance?

Accepted Answer

Aerobic endurance capacity

Answer

Iron is a component of hemoglobin; iron deficiency reduces the oxygen-carrying capacity of blood, most severely impairing aerobic endurance performance.

Question 5

"Low energy availability" in athletes is BEST described as:

Accepted Answer

Energy intake minus exercise energy expenditure leaving insufficient energy for physiological functions

Answer

Low energy availability is defined as dietary energy intake minus exercise energy expenditure, with the remainder being insufficient to support normal physiological processes such as hormone production and bone remodeling.
