MES Anatomy & Physiology for Special Populations 1 — Questions and Answers
Question 1: Which physiological adaptation is most commonly observed in individuals with type 2 diabetes who engage in regular aerobic exercise?
- Decreased insulin sensitivity
- Improved insulin sensitivity and glucose uptake (Correct answer)
- Increased fasting blood glucose
- Reduced mitochondrial density
Correct answer: Improved insulin sensitivity and glucose uptake
Regular aerobic exercise improves insulin sensitivity by increasing GLUT-4 transporter expression and enhancing glucose uptake in skeletal muscle.
Question 2: In a client with osteoporosis, which type of bone loading is most osteogenic?
- Low-impact repetitive loading
- High-impact dynamic loading (Correct answer)
- Static isometric loading
- Aquatic unloaded exercise
Correct answer: High-impact dynamic loading
High-impact dynamic loading generates the greatest mechanical stress on bone, stimulating osteoblast activity and promoting bone mineral density gains.
Question 3: Which muscle group is most commonly weakened in individuals with chronic low back pain due to prolonged sitting?
- Hamstrings
- Hip flexors
- Gluteus maximus and deep core stabilizers (Correct answer)
- Gastrocnemius
Correct answer: Gluteus maximus and deep core stabilizers
Prolonged sitting causes inhibition and atrophy of the gluteus maximus and deep core stabilizers, contributing to lumbar instability.
Question 4: What cardiovascular change is most characteristic of a deconditioned individual with heart failure?
- Elevated resting cardiac output
- Reduced stroke volume and exercise tolerance (Correct answer)
- Increased maximal heart rate
- Decreased systemic vascular resistance
Correct answer: Reduced stroke volume and exercise tolerance
Heart failure results in reduced stroke volume due to impaired ventricular function, leading to decreased exercise tolerance and VO2 max.
Question 5: In a post-stroke client, which neurological impairment most commonly affects safe exercise participation?
- Hypermobility of joints
- Spasticity and hemiplegia on one side of the body (Correct answer)
- Bilateral peripheral neuropathy
- Increased proprioceptive acuity
Correct answer: Spasticity and hemiplegia on one side of the body
Stroke commonly causes unilateral spasticity and hemiplegia due to upper motor neuron damage, affecting movement control and exercise safety.
Question 6: Which hormonal response is most relevant when designing exercise programs for clients with hypothyroidism?
- Excessive cortisol production limiting recovery
- Reduced metabolic rate affecting exercise intensity tolerance (Correct answer)
- Elevated growth hormone blunting fatigue
- Increased catecholamine release accelerating heart rate
Correct answer: Reduced metabolic rate affecting exercise intensity tolerance
Hypothyroidism reduces metabolic rate due to insufficient thyroid hormone, which can lower exercise tolerance and cause early fatigue.
