Exercise Physiology & Energy Systems (1–15)
1. What is the primary function of the neuromuscular system in sport
performance?
Control of voluntary and involuntary movements
Rationale: The neuromuscular system controls both conscious movements, like
sprinting, and involuntary reflexes, such as the stretch reflex. It coordinates neural
drive with muscle activation to produce efficient sports performance.
2. Which of the following is an example of anaerobic exercise?
Sprinting
Rationale: Anaerobic exercise involves high-intensity efforts lasting <2 minutes,
relying on ATP-PC and glycolytic pathways independent of oxygen.
3. What is the main role of lactate in exercise?
Lactate is a waste product of anaerobic metabolism
Rationale: During high-intensity glycolysis, pyruvate is converted to lactate, which
can be shuttled to other tissues for oxidation or converted back to glucose via the
Cori cycle.
4. What is the primary energy source for prolonged low-intensity exercise?
Fat
Rationale: Fat oxidation provides sustained ATP production during prolonged
,aerobic exercise when oxygen is available, sparing muscle glycogen for higher-
intensity demands.
5. Which hormone is most responsible for acute increases in blood glucose
during high-intensity exercise?
Glucagon and epinephrine
Rationale: Both increase hepatic glucose output, with epinephrine also stimulating
glycogen breakdown and glucagon promoting gluconeogenesis.
6. During rest and recovery, which autonomic nervous system branch
dominates?
Parasympathetic
Rationale: The parasympathetic system, via the vagus nerve, lowers heart rate,
promotes digestion, and facilitates recovery.
7. Which of the following best describes the function of Type IIx muscle fibers?
Low endurance and high force production
Rationale: Type IIx fibers are fast-twitch with high myosin ATPase activity; they
generate high power but fatigue rapidly due to low oxidative capacity.
8. What is the first metabolic pathway to supply ATP during an explosive
movement like a vertical jump?
ATP-PC system
Rationale: Stored ATP is used first, followed by phosphocreatine breakdown to
rapidly regenerate ATP within the first 5–10 seconds.
9. Which central and peripheral sites contribute to fatigue?
Activation of motor command, action potential propagation, excitation-
contraction coupling, and intracellular milieu status
Rationale: Fatigue is multifactorial, involving reduced neural drive, impaired
sarcolemma excitability, disrupted Ca²⁺ handling, and metabolic byproduct
accumulation.
10. What is the psychobiological model of fatigue?
Modification of intensity where fatigue occurs when required effort exceeds
, maximal effort the athlete is willing to exert
Rationale: This model emphasizes perceived exertion and motivation; athletes
stop when they believe continuation is impossible or effort is maximal.
11. What is the integrative governor theory?
Suggests both psychological and physiological factors limit performance,
focusing on subconscious avoidance of catastrophic failure
Rationale: This theory proposes the brain constantly monitors homeostasis and
paces effort to prevent severe disruption.
12. Which statement best describes the oxygen deficit during the onset of
constant-load exercise?
The lag between increased oxygen demand and steady-state oxygen uptake,
partially repaid by excess post-exercise oxygen consumption
Rationale: The oxygen deficit reflects anaerobic energy contribution until aerobic
metabolism fully adjusts.
13. Which measurement technique directly quantifies maximal oxygen
consumption (VO₂max)?
Open-circuit indirect calorimetry during a graded exercise test
Rationale: This gold-standard method analyzes expired gases to determine the
highest rate of oxygen consumption.
14. A 70 kg athlete produces an average power output of 300 W during a 10-
minute cycling time trial. What is the athlete’s approximate gross metabolic
efficiency if VO₂ is 3.5 L/min?
~26%
Rationale: Calculate: 300 W × 0.01433 = ~4.3 kcal/min energy expenditure. VO₂
3.5 L/min × 5 kcal/L O₂ = 17.5 kcal/min metabolic power. Efficiency = 4.3/17.5 ×
100 = 24.6% (energy cost of cycling ~1,000 W).
15. An 80 kg athlete has a resting VO₂ of 0.35 L/min and a maximal VO₂ of
4.0 L/min. What is the athlete’s maximal MET level?
11.4 METs
Rationale: VO₂max = 4.0 L/min → 4.0 L/min × 1,000 ml/L = 4,000 ml/min →
