Exercise Physiology Trivia Facts! Quiz - Quiz

Our bodies may have the same anatomy, but some of us have a hard time getting fit through exercises and being that you are planning to be a physiologist you need to understand the human body and how it reacts to a particular exercise. Below is an exercise physiology review quiz to see how much you understood. Take it up and see how good you do.

Questions and Answers

1.

Heavy resistance training and straining type exercises:
- A.
  
  Decrease blood pressure dramatically
- B.
  
  Increases the risk for individuals with existing hypertension or CAD
- C.
  
  Increases blood pressure dramatically because it compresses peripheral arterioles
- D.
  
  Both b and c
Correct Answer
D. Both b and c

Explanation
Both heavy resistance training and straining type exercises can increase blood pressure dramatically. Heavy resistance training puts strain on the cardiovascular system, leading to an increase in blood pressure. Additionally, these exercises can compress peripheral arterioles, further contributing to the increase in blood pressure. For individuals with existing hypertension or coronary artery disease (CAD), this can pose a greater risk as it can exacerbate their condition. Therefore, the correct answer is both b and c.

A thrombus:
- A.
  
  Can cause chest pain
- B.
  
  Severely impair normal heart unction
- C.
  
  Can be a form of a heart attack called myocardial infarction
- D.
  
  All of the above
Correct Answer
D. All of the above

Explanation
A thrombus refers to a blood clot that forms within a blood vessel. It can cause chest pain because it restricts blood flow to the heart, leading to reduced oxygen supply. This can severely impair normal heart function, potentially causing heart failure. In some cases, a thrombus can lead to a heart attack called myocardial infarction, where a portion of the heart muscle is damaged or dies due to lack of blood flow. Therefore, all of the given options are correct as they describe different consequences of a thrombus.

What are the three mechanical factors that determine myocardial oxygen uptake?
- A.
  
  Tension development within the myocardium, stroke volume, and blood pressure
- B.
  
  Blood pressure, tension development, and heart rate
- C.
  
  Myocardial contractility, heart rate, and blood pressure
- D.
  
  Tension development within the myocardium, myocardial contractility, and heart rate
Correct Answer
D. Tension development within the myocardium, myocardial contractility, and heart rate

Explanation
The three mechanical factors that determine myocardial oxygen uptake are tension development within the myocardium, myocardial contractility, and heart rate. Tension development within the myocardium refers to the force generated by the contraction of the heart muscle. Myocardial contractility refers to the ability of the heart muscle to contract and pump blood effectively. Heart rate is the number of times the heart beats per minute. These factors collectively determine the amount of oxygen that the myocardium requires to function properly.

Rate pressure product and oxygen uptake can be determined by:
- A.
  
  Diastolic and systolic blood pressure
- B.
  
  Systolic blood pressure and stroke volume
- C.
  
  Diastolic blood pressure and heart rate
- D.
  
  Systolic blood pressure and heart rate
Correct Answer
D. Systolic blood pressure and heart rate

Explanation
The rate pressure product is a measure of the oxygen demand of the heart and can be determined by multiplying the systolic blood pressure and heart rate. This is because the systolic blood pressure represents the force exerted on the walls of the arteries during the contraction of the heart, while the heart rate represents the number of times the heart beats per minute. Therefore, multiplying these two values provides an estimation of the oxygen demand of the heart.

5.

After a bout of sustained light to moderate intensity exercise:
- A.
  
  Systolic blood pressure increases
- B.
  
  Systolic blood pressure permanently drops
- C.
  
  Systolic blood pressure temporarily drops below pre exercise levels for up to 12 hours
- D.
  
  Diastolic blood pressure temporarily drops below pre exercise levels for up to 12 hours.
Correct Answer
C. Systolic blood pressure temporarily drops below pre exercise levels for up to 12 hours

Explanation
After a bout of sustained light to moderate intensity exercise, the systolic blood pressure temporarily drops below pre-exercise levels for up to 12 hours. This is because during exercise, the heart pumps more blood to meet the increased demand for oxygen and nutrients in the muscles. As a result, the blood vessels dilate, allowing for increased blood flow and lowering the resistance to blood flow. After exercise, it takes some time for the blood vessels to return to their normal state, causing a temporary drop in systolic blood pressure. This drop usually lasts for up to 12 hours before returning to pre-exercise levels.

6.

Blood pressure is equal to:
- A.
  
  Cardiac output divided by heart rate
- B.
  
  Cardiac output multiplied by stroke volume
- C.
  
  Cardiac output multiplied by total peripheral resistance
- D.
  
  Blood pressure divided by cardiac output
Correct Answer
C. Cardiac output multiplied by total peripHeral resistance

Explanation
Blood pressure is determined by the amount of blood pumped by the heart (cardiac output) and the resistance encountered by the blood vessels (total peripheral resistance). When the heart pumps more blood and the resistance in the blood vessels is higher, the blood pressure increases. Therefore, the correct answer is "cardiac output multiplied by total peripheral resistance" because both factors contribute to determining blood pressure.
