EXSC 191 Exam 2 ACTUAL UPDATED
Exam Questions and CORRECT Answers
cardiorespiratory endurance - CORRECT ANSWER the ability of the heart, lungs, and
blood vessels to deliver adequate amounts of oxygen to the cells to meet the demands of
prolonged physical activity, determines how well essential systems work together for long
periods of physical activity
Basic Cardiorespiratory Physiology - CORRECT 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 - CORRECT 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 - CORRECT ANSWER elastic/unobstructed, carries deoxygenated blood, relies on
pumping action of muscles to facilitate venous return
Oxygen Uptake (VO2) - CORRECT ANSWER capacity of the body to deliver and utilize
oxygen, higher capacity=greater efficiency
maximal oxygen uptake (VO2 max) - CORRECT ANSWER maximum amount of oxygen
the body us able to use per minute of physical activity, expressed in L/min
factors affecting VO2 max - CORRECT 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 - CORRECT 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 - CORRECT 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 - CORRECT 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 - CORRECT 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 - CORRECT ANSWER <24.9 in men, <23.9 in women
Fair VO2 max - CORRECT ANSWER 25-33.9 in men, 24-30.9 in women
Average VO2 max - CORRECT ANSWER 34-43.9 in men, 31-38.9 in women
Good VO2 max - CORRECT ANSWER 44-52.9 in men, 39-48.9 in women
Excellent VO2 max - CORRECT ANSWER >53 in men, >49 in women
, 1.0 Mile Walk Test - CORRECT 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 - CORRECT 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 - CORRECT ANSWER distance completed in amount of time, should
be limited to skilled/conditioned swimmers, considered maximal test
maximal heart rate - CORRECT ANSWER 208 - (0.7 x age)
Target zone - CORRECT ANSWER calculate 65%-80% of maximal heart rate
stroke volume - CORRECT ANSWER the amount of blood pumped per beat by the left
ventricle, exercise increases this
ejection fraction - CORRECT ANSWER the amount of blood pumped out of the heart
with each beat, referred to as percentage, related to stroke volume
cardiac output - CORRECT ANSWER amount of blood pumped by the heart per minute,
product of stoke volume and heart rate (SV x HR), exercise increases this but stays the same at
rest between fit and unfit individuals, increases proportionally with intensity
overload principle - CORRECT ANSWER for a muscle to get stronger, it must be worked
against a load greater than normal, doing more that normal is necessary to force the body to
adapt to the challenge
