Question 1Functional anatomy and exercise physiology

What acute cardiovascular response occurs immediately upon commencing strenuous exercise to meet increased muscular oxygen demand?

  1. Decreased stroke volume
  2. Constriction of active skeletal muscle arterioles
  3. Decreased systolic blood pressure
  4. Increased cardiac output (Q = HR x SV) Correct answer.

Explanation

Cardiac output (Q) increases rapidly during exercise as both heart rate (HR) and stroke volume (SV) rise to transport oxygenated blood to active muscles.

Question 2Functional anatomy and exercise physiology

Which chronic adaptation results from long-term aerobic endurance training?

  1. Decreased capillary density surrounding slow-twitch muscle fibers
  2. Decreased mitochondrial size and number
  3. Increased left ventricular cavity size and stroke volume Correct answer.
  4. Decreased resting arteriovenous oxygen difference

Explanation

Aerobic endurance training leads to cardiac hypertrophy (specifically left ventricular cavity enlargement), enabling a larger stroke volume at rest and during exercise.

Question 3Functional anatomy and exercise physiology

What physiological process accounts for Excess Post-exercise Oxygen Consumption (EPOC) following high-intensity anaerobic exercise?

  1. Replenishing intramuscular PC stores, clearing metabolic by-products, and restoring elevated body temperature/heart rate Correct answer.
  2. Synthesizing new muscle proteins to repair micro-tears immediately
  3. Converting blood glucose into stored liver glycogen within seconds
  4. Decreasing pulmonary ventilation below resting baseline levels

Explanation

EPOC represents elevated oxygen consumption post-exercise. The fast component restores ATP and PC stores and oxygenates myoglobin; the slow component metabolizes lactate, supports elevated heart rate, and clears heat.

Question 4Functional anatomy and exercise physiology

During exercise, an athlete's tidal volume is 2.5 L per breath and respiratory rate is 40 breaths per minute. What is their minute ventilation (VE)?

  1. 16 L/min
  2. 42.5 L/min
  3. 0.0625 L/min
  4. 100 L/min Correct answer.

Explanation

Minute Ventilation (VE) = Tidal Volume (TV) x Respiratory Rate (RR) = 2.5 L x 40 breaths/min = 100 L/min.

Question 5Functional anatomy and exercise physiology

How does the arteriovenous oxygen difference (a-vO2 diff) change from rest to maximal aerobic exercise?

  1. It decreases to zero because muscles stop using oxygen
  2. It remains completely unchanged at all exercise intensities
  3. It increases significantly as working muscle tissues extract more oxygen from systemic arterial blood Correct answer.
  4. It fluctuates randomly depending on environmental humidity

Explanation

At rest, arterial blood carries ~20 mL O2/100 mL and venous blood returns ~15 mL, giving an a-vO2 diff of 5 mL. During maximal exercise, muscles extract far more oxygen, dropping venous content to ~3-5 mL, increasing a-vO2 diff to 15-17 mL O2/100 mL.

Question 6Functional anatomy and exercise physiology

How does increased capillary density around skeletal muscle fibers benefit an endurance athlete?

  1. It increases the speed of nerve impulse transmission along motor neurons
  2. It enhances oxygen and nutrient delivery to muscle cells while expediting removal of metabolic waste Correct answer.
  3. It decreases the surface area available for gas exchange
  4. It increases total blood viscosity, making blood thicker

Explanation

Capillarisation shortens the diffusion distance between blood and mitochondria, expanding surface area for oxygen uptake and accelerating removal of carbon dioxide and lactate.

Question 7Functional anatomy and exercise physiology

An athlete exercising on a treadmill has a measured heart rate of 160 bpm and a stroke volume of 125 mL (0.125 L). Calculate their cardiac output (Q).

  1. 1.28 L/min
  2. 28.5 L/min
  3. 200.0 L/min
  4. 20.0 L/min Correct answer.

Explanation

Cardiac Output (Q) = Heart Rate (HR) x Stroke Volume (SV) = 160 bpm x 0.125 L = 20.0 L/min.

Question 8Functional anatomy and exercise physiology

In intermittent sprint sports (e.g., Australian Rules Football), what physiological mechanism dictates the rate of intramuscular phosphocreatine (PC) re-synthesis during short rest intervals?

  1. Anaerobic glycolysis producing high lactic acid to rebuild PC
  2. Ingestion of simple sugars during the 30-second rest break
  3. Conversion of muscle protein into PC stores
  4. Aerobic delivery of oxygen to mitochondria to produce ATP, which donates phosphate to creatine (fast EPOC component) Correct answer.

Explanation

PC re-synthesis is an aerobic process occurring in mitochondria. Oxygen delivered during rest intervals drives aerobic ATP production, which then phosphorylates free creatine back into PC (t1/2 = ~30 seconds).

Question 9Functional anatomy and exercise physiology

Using the Fick Equation (VO2 = Q x a-vO2 diff), calculate an athlete's maximal oxygen consumption (VO2 max) if their maximal cardiac output (Q) is 25.0 L/min and their maximal a-vO2 difference is 160 mL O2/L blood (0.16 L O2/L).

  1. 156.25 L/min
  2. 41.0 L/min
  3. 0.0064 L/min
  4. 4.0 L/min Correct answer.

Explanation

VO2 max = Q x a-vO2 diff = 25.0 L/min x 0.16 L O2/L = 4.0 L/min.
