, Question 1
Which of the following best explains the phenomenon where cardiac output
increases during exercise despite a decrease in systemic vascular resistance?
A. Baroreceptor reflex activation increases heart rate and contractility.
B. Sympathetic cholinergic vasodilation in skeletal muscle overrides
sympathetic vasoconstriction.
C. Cardiopulmonary baroreceptors reduce parasympathetic outflow while
muscle mechanoreceptors increase sympathetic outflow.
D. Local metabolic vasodilation in active muscle reduces afterload,
allowing stroke volume to increase via the Frank-Starling mechanism.
Correct Answer: C - Cardiopulmonary baroreceptors reduce
parasympathetic outflow while muscle mechanoreceptors increase
sympathetic outflow.
RATIONALE
During exercise, cardiopulmonary baroreceptors and muscle
mechanoreceptors and metaboreceptors reset the baroreflex, leading to
reduced parasympathetic and increased sympathetic outflow, which
raises heart rate and contractility. This increase in cardiac output
occurs even as systemic vascular resistance falls due to local
vasodilation. Option D is partially correct but does not fully explain
the neural integration; A and B are incorrect because baroreceptor
reflex is reset and sympathetic cholinergic vasodilation is not the
primary mechanism in humans.
Question 2
In a biomechanical analysis of a countermovement jump, which factor most
directly accounts for the increased jump height compared to a squat jump?
A. Increased pre-stretch of the series elastic component, enhancing force
via the stretch-shortening cycle.
B. Greater motor unit recruitment due to longer contraction time.
C. Higher rate of force development from increased muscle activation.
Page 2
, D. Reduced inhibitory signals from Golgi tendon organs during the
eccentric phase.
Correct Answer: A - Increased pre-stretch of the series elastic
component, enhancing force via the stretch-shortening cycle.
RATIONALE
The countermovement jump utilizes the stretch-shortening cycle,
where pre-stretch of the series elastic component (e.g., tendons) stores
elastic energy and enhances force production during the subsequent
concentric phase. While motor unit recruitment and rate of force
development contribute, the primary mechanism for the increased
height is the exploitation of elastic energy. Option D is not the main
factor.
Question 3
Which statement accurately describes the role of the cerebellum in motor
learning?
A. It is primarily responsible for the initial acquisition of motor skills.
B. It integrates sensory feedback to correct ongoing movements and is
essential for adaptation and error-based learning.
C. It stores long-term motor memories independently of the cerebral
cortex.
D. It generates the initial motor command before cortical processing.
Correct Answer: B - It integrates sensory feedback to correct
ongoing movements and is essential for adaptation and
error-based learning.
Page 3
, RATIONALE
The cerebellum is crucial for error-based learning and real-time
correction of movements by comparing intended and actual outcomes
using sensory feedback. It does not initiate motor commands (that is
cortical) nor store long-term memories alone; the basal ganglia and
cortex are also involved in acquisition and storage. Thus, B is the most
accurate.
Question 4
A marathon runner consumes a high-carbohydrate diet and performs
carbohydrate loading. Which of the following is the primary mechanism by
which this strategy enhances endurance performance?
A. Increased fat oxidation, sparing muscle glycogen.
B. Elevated muscle glycogen stores, delaying the onset of fatigue.
C. Enhanced ketone body production, providing an alternative fuel.
D. Improved thermal regulation due to increased blood volume.
Correct Answer: B - Elevated muscle glycogen stores, delaying
the onset of fatigue.
RATIONALE
Carbohydrate loading maximizes muscle glycogen stores, which are
the primary fuel for high-intensity endurance exercise. This delays
glycogen depletion and fatigue. While fat oxidation and other factors
may play minor roles, the main benefit is increased glycogen
availability. Ketone production is not a primary outcome of
carbohydrate loading.
Question 5
Which of the following best describes the concept of 'exercise is medicine' in
the context of chronic disease management?
A. Exercise should be prescribed as a first-line treatment for all chronic
diseases.
