  1. During resistance training, EPOC (excess post-exercise oxygen consumption) is PRIMARILY elevated due to:

    Answer: Restoration of oxygen stores, PCr resynthesis, and elevated metabolism from hormonal response

    EPOC after intense resistance training reflects the oxygen cost of replenishing PCr, clearing lactate, restoring body temperature, and catecholamine-driven metabolic elevation.

  2. A Golgi tendon organ (GTO) fires in response to:

    Answer: High muscle tension, causing reflexive muscle relaxation

    GTOs are tension-sensitive mechanoreceptors that trigger the autogenic inhibition reflex, causing the muscle to relax when tension becomes dangerously high.

  3. Which of the following BEST describes the concept of 'progressive overload'?

    Answer: Gradually increasing training stress over time to continue driving adaptation

    Progressive overload means systematically increasing volume, intensity, or complexity so the body continues to adapt beyond its current capacity.

  4. Which metabolic substrate provides the GREATEST proportion of fuel during low-intensity, prolonged exercise (e.g., 30–40% VO₂max)?

    Answer: Fat (free fatty acids)

    At low intensities (≤40% VO₂max), fat oxidation dominates fuel use because the slow aerobic pathway efficiently metabolizes free fatty acids.

  5. What is the normal resting cardiac output for an average adult?

    Answer: 5–6 liters per minute

    Resting cardiac output averages ~5 L/min (HR ~70 bpm × SV ~70 mL), and can rise to 20–25 L/min during maximal exercise in trained individuals.

  6. Muscle soreness that peaks 24–72 hours after unaccustomed eccentric exercise is called:

    Answer: Delayed onset muscle soreness (DOMS)

    DOMS results from micro-tears and inflammatory responses in muscle tissue and connective fibers, peaking 24–72 hours post-eccentric exercise.

  7. Which of the following best describes the 'oxygen-carrying capacity' adaptation seen with endurance training?

    Answer: Increased total hemoglobin mass and blood plasma volume

    Endurance training increases plasma volume and total hemoglobin, enhancing the blood's ability to carry and deliver oxygen to working muscles.
