EXSC 191 2 ACTUAL TEST PAPER 2026
QUESTIONS WITH SOLUTIONS GRADED A+
●● Basic Cardiorespiratory Physiology.
Answer: heart pumps oxygenated blood to muscles, heart receives
deoxygenated blood from tissues, heart pumps deoxygenated blood to
lungs, reoxygenated blood is pumped through body
●● arteries.
Answer: elastic/unobstructed, the size of the diameter is under muscular
control, carries oxygenated blood, those that are unfit have a reduced
diameter of become inelastic
●● veins.
Answer: elastic/unobstructed, carries deoxygenated blood, relies on
pumping action of muscles to facilitate venous return
●● Oxygen Uptake (VO2).
Answer: capacity of the body to deliver and utilize oxygen, higher
capacity=greater efficiency
●● maximal oxygen uptake (VO2 max).
,Answer: maximum amount of oxygen the body us able to use per minute
of physical activity, expressed in L/min
●● factors affecting VO2 max.
Answer: genetics, gender (15%-30% higher in men), age (decreases
1%/year starting at 25, only 0.5% for active people), training state, and
body composition
●● health benefits of aerobic fitness.
Answer: reduces risk of early death, coronary heart disease, and CHD
risk factors, protection against health risks associated with obesity,
enhances the ability to perform various tasks, improves ability to
function, associated with a feeling of well-being
●● aerobic exercise.
Answer: exercise that requires oxygen to produce the necessary energy
for the activity, primary type of exercise that stimulates improvements in
the cardiorespiratory system
●● Benefits of aerobic exercise.
Answer: higher VO2 max, increase in red blood cell count, decrease in
resting heart rate, increase in cardiac muscle strength, lower heart rate in
workouts, increased number of functional capillaries, faster recovery
time, lower blood pressure/blood lipids, increase in number, size, and
capacity of mitochondria, increase of fat-burning enzymes
,●● Rationale for Cardiorespiratory Assessment.
Answer: - Educate participants regarding present fitness levels
- To motivate individuals to participate in exercise programs
- To provide a foundation for exercise prescription
- To evaluate improvements achieved through exercise programs and
make adjustments
- To monitor changes in fitness over the years
●● Poor VO2 max.
Answer: <24.9 in men, <23.9 in women
●● Fair VO2 max.
Answer: 25-33.9 in men, 24-30.9 in women
●● Average VO2 max.
Answer: 34-43.9 in men, 31-38.9 in women
●● Good VO2 max.
Answer: 44-52.9 in men, 39-48.9 in women
●● Excellent VO2 max.
, Answer: >53 in men, >49 in women
●● 1.0 Mile Walk Test.
Answer: for individuals unable to run because of low fitness levels of
injuries, estimates VO2max based on prediction equation that requires:
time to complete course, heart rate at the end of the test, body weight,
and gender
●● Step Test.
Answer: estimates VO2max based on 3 minute test
-height= 16 1/4"
take 15 sec heart rate between 5-20 seconds into recovery
advantages: short amount of time, little equipment
●● 12 Min Swim Test.
Answer: distance completed in amount of time, should be limited to
skilled/conditioned swimmers, considered maximal test
●● maximal heart rate.
Answer: 208 - (0.7 x age)
●● Target zone.
Answer: calculate 65%-80% of maximal heart rate
