Question 1

Protein plays less of a role in energy production during exercise than either carbohydrates or fats; however, it is possible to metabolize some protein during exercise. Which of the following are considered the "building blocks" of proteins?

A)Calcium and sodium
B)Amino acids
C)Triglycerides
D)Lipids

Answer 1

Amino acids

Question 2

When performing any type of physical activity, skeletal muscles need to contract to make the body move. All of the following factors influence the ability of skeletal muscle to contract EXCEPT:

A)Speed of contraction
B)Rate of myosin cross-bridge movement
C)Muscle size
D)Efficiency of muscle fibers

Answer 2

Muscle size

Question 3

There is no such person as Frank Starling. Contrary to popular belief, he never had his own law. Instead, in the late19th century, a man named Otto Frank performed research (with frogs) that was later extrapolated by Ernest Starling (with dogs). Which of the following MOST adequately depicts the Frank-Starling mechanism?

A)A body at rest will stay at rest; a body in motion will stay in motion
B)The strength of ventricular contraction is increased when the ventricle is stretched prior to contraction
C)For every action, there is an opposite and equal reaction
D)The strength by which a nerve or muscle fiber responds to a stimulus is not dependent on the strength of the stimulus

Answer 3

The strength of ventricular contraction is increased when the ventricle is stretched prior to contraction

Question 4

A class member confides that she has gained 4 lbs since Thanksgiving. Is it time for alarm? In general, any gain in weight that can be attributed to an increase in lean body mass is a good weight gain. Which of the following structures is LEAST likely to be a component of lean body tissue?

A)Bone
B)Blood
C)Muscle
D)Essential fat

Question 5

One of the most noticeable physical differences between men and women is the presence - or absence -- of body fat. Because men do not need nearly the quantity of essential body fat, their total amount of fat is often much lower than their female counterparts. What is the ESSENTIAL level of body fat for women?

A)2-5%
B)6-9%
C)10-13%
D)12-16%

Question 6

The efficiency of the human heart is a beautiful thing. All four chambers work in a beautiful, synchronized effort to do one thing well: push blood. When disease compromises the heart's ability to function, the result is often a reduction in "ejection fraction" (EF) or the percentage of the end diastolic volume ejected with each contraction. What is a normal value for EF at rest?

A)50-60%
B)60-70%
C)60-80%
D)70-80%

Question 7

Wolff's Law relates to which of the following?

A)Nervous system arousal
B)Heart tissue efficiency
C)Muscle composition
D)Bone mass and distribution

Question 8

Which of the following characteristics would NOT be found in a student-centered instructor?

A)Provides consistent encouragement
B)Has and shares knowledge of attainable goals
C)Fosters dependence in participants
D)Is centered on reality
