Personal Trainer Practice Questions
A personal trainer is an individual certified to have a varying degree of knowledge of general fitness involved in exercise prescription and instruction. Before certification, a personal trainer must excel in the practice qualification exams. As a result, we have compiled some questions for you to practice before the big deal.
- 1.
Which organ system is responsible for the transport of nutrients, removal of waste and overall environmental maintenance to support the body's function?
- A.
Respiratory
- B.
Reproductive
- C.
Cardiovascular
- D.
Endocrine
Correct Answer
B. Reproductive -
- 2.
What relays information to the central nervous system about changes in the body and limbs' positions due to muscular motions?
- A.
Muscle spindles
- B.
Motor endplates
- C.
Proprioceptors
- D.
Nerve cells
Correct Answer
B. Motor endplatesExplanation
Motor endplates are specialized structures located at the neuromuscular junction, where the motor neuron connects with the muscle fiber. They play a crucial role in relaying information to the central nervous system about changes in the body and limbs' positions due to muscular motions. When a muscle contracts or stretches, the motor endplates detect these changes and send signals to the brain, allowing for coordination and control of movement. Therefore, motor endplates are responsible for providing proprioceptive feedback, which helps in maintaining body posture and executing precise movements.Rate this question:

What controls the process of changing membrane potential in the nerve cell membrane by allowing sodium ions to rush into the cell?
- A.
Depolarization
- B.
Saltatory conduction
- C.
Sodium-potassium pump
- D.
Hyperpolarization
Correct Answer
A. DepolarizationExplanation
Depolarization is the process that controls the changing of membrane potential in a nerve cell membrane by allowing sodium ions to rush into the cell. During depolarization, the cell membrane becomes less negative, and this change in charge triggers the opening of sodium channels, allowing sodium ions to flow into the cell. This influx of positive ions further depolarizes the cell and generates an electrical impulse, which is essential for the transmission of nerve signals.Rate this question:

What part within the muscle fiber stores glycogen and myoglobin and is made up of lipids, enzymes and various types of cellular organelles?
- A.
Transverse tubules
- B.
Myofibrils
- C.
Sarcolemma
- D.
Sarcoplasm
Correct Answer
C. SarcolemmaExplanation
The sarcolemma is the correct answer because it is the part within the muscle fiber that stores glycogen and myoglobin. It is also composed of lipids, enzymes, and various types of cellular organelles. The sarcolemma is the cell membrane of the muscle fiber and plays a crucial role in maintaining the integrity and function of the muscle cell.Rate this question:

Which of these signs/symptoms is synonymous with ischemia?
- A.
Dizziness
- B.
Difficulty breathing with usual activities
- C.
Pain (tightness) or discomfort in jaw
- D.
Pain sensations or cramping in lower extremities
Correct Answer
B. Difficulty breathing with usual activitiesExplanation
Ischemia refers to a reduced blood supply to a particular organ or tissue. Difficulty breathing with usual activities can be a sign of ischemia because it indicates that there is not enough blood flow to meet the oxygen demands of the body during physical exertion. This can be caused by narrowed or blocked blood vessels, such as in the case of ischemic heart disease. The other signs/symptoms mentioned, including dizziness, pain or discomfort in the jaw, and pain or cramping in the lower extremities, may be associated with other conditions but are not directly synonymous with ischemia.Rate this question:

Which of these forms states that the client is acknowledging having been notified about the risks associated with exercise?
- A.
Release of Liability
- B.
Waiver
- C.
Informed Consent
- D.
Medical Release
Correct Answer
A. Release of LiabilityExplanation
The form that states that the client is acknowledging having been notified about the risks associated with exercise is the Release of Liability. This form typically includes a statement where the client acknowledges that they understand the potential risks involved in participating in physical activities and that they are voluntarily assuming these risks. By signing this form, the client agrees to release the organization or individual from any liability in case of injury or harm during the exercise.Rate this question:

Which is a cardiovascular disease characterized by hardening of arteries as well as thickening of arterial walls and loss of elasticity?
- A.
Arthritis
- B.
Atherosclerosis
- C.
Chronic Obstructive Pulmonary Disease (COPD)
- D.
Diabetes
Correct Answer
C. Chronic Obstructive Pulmonary Disease (COPD) -
- 8.
A blood pressure of 142/92 is considered...
- A.
Low
- B.
Moderate
- C.
Normal
- D.
High
Correct Answer
D. HighExplanation
A blood pressure of 142/92 is considered high because it falls within the range of hypertension. Hypertension is a condition characterized by consistently elevated blood pressure levels, which can increase the risk of various health problems such as heart disease, stroke, and kidney disease. The top number, 142, represents the systolic pressure, which measures the pressure in the arteries when the heart beats. The bottom number, 92, represents the diastolic pressure, which measures the pressure in the arteries when the heart is at rest between beats.Rate this question:

What are Beta Blockers?
- A.
Increase blood pressure and decrease heart rate
- B.
Increase heart rate and increase blood pressure
- C.
Decrease heart rate and decrease blood pressure
- D.
Increase heart rate and decrease blood pressure
Correct Answer
C. Decrease heart rate and decrease blood pressureExplanation
Beta blockers are medications that work by blocking the effects of adrenaline on the body's beta receptors. By doing so, they decrease the heart rate and the force of contractions, which ultimately leads to a decrease in blood pressure. This is why the correct answer is "Decrease heart rate and decrease blood pressure." Beta blockers are commonly prescribed to treat conditions such as high blood pressure, angina, and certain heart rhythm disorders.Rate this question:

Which of the following medications produces a lower heart rate at rest and while exercising?
- A.
Antidepressants
- B.
Diuretics
- C.
Beta Blockers
- D.
Antihistamines
Correct Answer
C. Beta BlockersExplanation
Beta blockers are a class of medications that work by blocking the effects of adrenaline on the heart. By doing so, they reduce the heart rate and decrease the force of contractions, resulting in a lower heart rate at rest and during exercise. This makes beta blockers an effective treatment for conditions such as high blood pressure, angina, and certain heart rhythm disorders. Antidepressants, diuretics, and antihistamines do not have the same effect on heart rate as beta blockers.Rate this question:
