CFP Exercise Science & Physiology 1

Question 1

What is the primary energy system used during short bursts of intense exercise, such as sprinting?

Accepted Answer

Phosphagen system

Answer

Aerobic system

Answer

Lactic acid system

Answer

Glycolytic system

Question 2

What is the primary function of the cardiovascular system during exercise?

Accepted Answer

Answer

To provide structural support to the bones.

Answer

To regulate body temperature by sweating.

Answer

To deliver oxygen and nutrients to muscles and remove waste products like carbon dioxide.

Answer

To enhance muscle strength during exercise.

Question 3

What is the role of mitochondria in muscle cells during exercise?

Accepted Answer

Answer

They store energy in the form of glucose.

Answer

They produce ATP for energy through aerobic processes.

Answer

They regulate the contraction of muscles.

Answer

They store waste products generated during exercise.

Question 4

Which of the following best describes muscle hypertrophy?

Accepted Answer

Answer

An increase in muscle endurance without a change in size.

Answer

An increase in muscle size due to an increase in muscle fiber volume.

Answer

A decrease in muscle mass due to inactivity.

Answer

A decrease in fat storage in the muscles.

Question 5

What is the effect of aerobic exercise on the cardiovascular system?

Accepted Answer

Answer

It decreases the resting heart rate and increases the efficiency of oxygen delivery.

Answer

It decreases stroke volume and raises blood pressure.

Answer

It decreases the overall strength of the heart.

Answer

It reduces blood flow to muscles.

Question 6

What is the primary function of the skeletal system during exercise?

Accepted Answer

Answer

To produce energy for muscle contractions.

Answer

To absorb oxygen and distribute it to muscles.

Answer

To support the body and facilitate movement by providing attachment points for muscles.

Answer

To regulate body temperature during exercise.

Question 7

What is the role of the endocrine system in exercise?

Accepted Answer

Answer

It regulates muscle contraction directly.

Answer

It produces hormones that influence energy production and stress response.

Answer

It increases blood pressure during rest.

Answer

It decreases the release of insulin during exercise.

Question 8

What is the physiological response of the body to resistance training?

Accepted Answer

Answer

It decreases muscle mass while increasing endurance.

Answer

It causes muscle fibers to become stronger and thicker through repair after microtears.

Answer

It reduces flexibility but increases muscle strength.

Answer

It increases fat storage in muscles.

Question 9

What is the importance of flexibility training in exercise physiology?

Accepted Answer

Answer

It increases muscle strength.

Answer

It improves joint mobility and reduces muscle tightness, helping prevent injuries.

Answer

It is only necessary for advanced athletes.

Answer

It decreases muscle endurance.
