KNR 280 Illinois State University -Exercise Physiology
Exam II Questions | 2026/2027 | Answers Correct | With
Complete Solutions
"second wind" Correct Answers occurs once an individual has
surpassed the O2 deficit
A highly trainined endurance athlete would likely have a _____
RER at rest than an untrained individual Correct Answers
lower (closer to 0.7)
aerobic performance indicators Correct Answers - VO2 max
- lactate threshold (LT)
- running economy
account for ~97.6 of variation in run time
anaerobic capacity Correct Answers maximal amount of
energy produced by ATP-CP and anaerobic glycolysis
ANAEROBIC GLYCOLYSIS provides the most ATP to
achieve
At rest, the RER of an aerobically trained athlete would likely be
_____ than the RER of an anerobically trained athlete Correct
Answers lower
ATPase Correct Answers enzyme that catalyzes hydrolysis of
ATP; responsible for the ability to breakdown ATP for energy
ATP -> (ATPase) -> ADP + Pi + energy for work + heat
, ATPase activity _____ in response to exercise training and ____
in response to lactate accumulation Correct Answers increases;
decreases
causes of plateau and retrogression Correct Answers - genetic
barriers
- too many competitions
- poor sleep
- life stressors
- illness
MOST of the time, related to overreaching and overtraining
cool down Correct Answers lowers lactate levels following
intense exercise at a faster pace than at rest
- clears lactate (4 ways)
- regenrates CP
- regulates HR and breathing
CP or glycogen depletion Correct Answers impaired ATP
production; CHO loading and creatine supplementation can
reduce rate of depletion
creatine kinase (CK) Correct Answers rate-limiting enzyme of
the ATP-CP PATHWAY
found in skeletal and cardiac muscle; catalyzes the reaction that
takes place in the ATP-CP pathway
