How does taking “high” doses of vitamin C impact health?
More is not always better. In some cases, increasing the dosage does not come with many adverse effects, but it also does not increase health benefits. An increased dose of Vitamin C over 1 g reduces absorption.
How would age and overall health affect testosterone levels among men?
A reduction in testosterone levels occurs with age, and overall health may affect the degree of change.
What does the electron transport chain (ETC) do?
The ETC uses a hydrogen gradient to create ATP.
Which of the following is true of protein shakes?
They are convenient options for increasing protein intake.
What measurement is dependent upon the length of the lever arm and the angle between the force application and the lever arm?
Torque
Pronation of the foot describes what multiplanar movements?
Eversion, dorsiflexion, and ankle abduction
Which characteristic is exhibited by type I muscle fibers?
Slow to fatigue
Where in the digestive system are most fluids absorbed?
Small intestine
Which of the following nutrition topics are within the scope of practice for a Certified Personal Trainer?
General guidance on the importance of nutrition for health and performance
What types of foods provide all the essential amino acids?

What best describes an essential amino acid?
An amino acid that must be obtained via diet, as it is not produced by the body
What type of muscle action would expend the highest amount of energy at a fixed resistance level over a comparable duration?
Concentric
What is cardiac output?
The volume of blood pumped by the heart per minute
What is acidosis in muscle?
