EXPH 386 Test 2The intensity and duration of the exercise and the fitness level of the individual - Answer-What are the
contributions from the various pathways of energy metabolism dependent on?
Primarily from glucose and stored glycogen during the anaerobic process of glycolysis resulting primarily
in the formation of lactic acid - Answer-Where does the energy to replace the high-energy phosphates
during strenuous exercise come from?
NO - Answer-Does blood lactate accumulate at all levels of exercise?
No, it only appears in higher amounts during higher intensity exercise - Answer-Does lactic acid appear
in the blood during all types of exercise?
Hypoxia - Answer-Low oxygen
Increases the rate of glycolysis - Answer-What does relative hypoxia do?
Anaerobic Threshold or Blood Lactate Threshold - Answer-The threshold for lactate buildup
-Genetic endowment (Muscle Fiber Type)
, -Adaptations that cause less lactic acid production
-Greater rate of removal
-Metabolize lactate at muscular level - Answer-Why could an athlete's threshold for lactate buildup
occur at a higher percent of the athletes aerobic capacity?
-Increased capillary density
-Increased number and size of mitochondria
-Increase in aerobic enzymes and transfer agents - Answer-What may cause adaptations and increased
removal of lactate?
80-90% - Answer-At what percent of maximal capacity for aerobic metabolism can trained athletes
perform at before significant increases in blood lactate occur?
20-30% - Answer-How much higher is an athletes blood lactate levels after performing maximal short-
term exercise than an untrained individual?
Steady State (Rate) - Answer-Balance between the energy required by working muscles and the rate of
ATP production via aerobic metabolism
Oxygen Deficit - Answer-The difference between the total oxygen consumed during exercise and the
total that would have been consumed had a steady rate of aerobic metabolism been reached
immediately
A trained individual - Answer-Would oxygen deficit be lower for a trained or untrained individual?
Fast Twitch (Type 2) Muscle Fibers - Answer--Possess a high capability for anaerobic production of ATP
during glycolysis
-Activated during change-of-pace (stop-and-go) activities (basketball, hockey, etc.)
-Activated during all-out exercise
