KINES 314 (EXAM 3) UW-MADISON
QUESTIONS AND ANSWERS
What % does VO2 max decline per year after the age of 40? - Correct Answers -1 % a
year roughly
At what age does endurance performance (in time) see a non-linear increase? - Correct
Answers -After the age of 60 performance starts to rapidly decline
What Fick equation variables change with aging and detraining? - Correct Answers --
Max HR decreases as one gets older...HRmax=220-Age
-Decrease in maximal stroke volume... this variable is the main factor in decreased
VO2max in men
-Decrease in maximal a-vO2 difference...this is more so common in women
3 weeks of extreme detraining is essentially the same as how many years of primary
aging? - Correct Answers -3 weeks of extreme detraining is the same as 30 years of
aging
What is the definition of sarcopenia? - Correct Answers -Age related loss of skeletal
muscle mass
At what age does skeletal muscle mass start to decline? - Correct Answers -50, this is
due to sarcopenia
How did the Fick equation variables change during the 3-week bed rest study? - Correct
Answers --HRmax...This variable actually increased a little bit, probably because of
increased SNS activity
-SV...Stroke Volume saw severe reductions following the bed rest study. As a result,
there was a large decrease in CO.
-a-vO2...This variable really did not drop that much during the 3-week bed rest study.
However, after 3-weeks of detraining a-vO2 started to decrease rapidly
Why is exercising in the heat so stressful on the body? - Correct Answers -The
competition existing between trying to cool the body off and maintaining MAP. If the
body vasodilates more then the MAP drops.
