Lecture exam 2 (metabolism up to anaerobic glycolysis) Flashcards
Metabolism as it pertains to exercise
how we produce ATP to give energy for activity
Metabolism underlies this
all forms of muscle contraction
This must continuously be produced during exercise
ATP
This to exercise training change the metabolic process
adaptations
exercise training programs are best designed on this
metabolic needs of the activity
Knowing the metabolic needs of the activity does this
allows us to refine training process
Metabolism =
to change
anabolism =
to build up, produce ATP
catabolism =
to breakdown, breakdown of foodstuffs to produce ATP
Two types of ATP production
aerobic and anaerobic
aerobic ATP production
producing ATP in situtations where enough O2 in cell
anaerobic ATP production
producing ATP W/O O2
Aerobic intensity
moderate
Anaerobic intensity
greater intensity
anaerobic energy substrates
phosphogens (CP, ATP) carbohydrates in form of glucose
aerobic energy substrates
carbohydrates, proteins, fats
T/F: most activities are a blend of aerobic and anaerobic
T
Long-duration actvivites use primarily this
aerobic metabolism
high intensity activities use primarily this
anaerbic metabolism
In enchance training mach this to this
match the activity (exercise) to desired activity (sport)
ability to recover in between exercise
aerobic base
Time course of involvement of metabolic pathways (3)
phosphogens to glycolytic to oxidative (fig 3.6 pg 50)
time is important to this
power production
Work =
F x D
Power =
Work / time
the amount of ATP that can be produced
capacity
the amount of ATP produced/unit time
power
The most to least powerful energy producing systems
phosphogen system
anaerobic glycolysis (of carbs)
carbohydrate oxidation (aerobic)
fatty acid oxidation
Time to produce ATP from fastest to slowest
phosphogen system
anaerobic glycolysis (of carbs)
carbohydrate oxidation (aerobic)
fatty acid oxidation
Phosphogen system (ATP-PC system) is used at this intensity
100% intensity
Anaerobic glycolysis of carbohydrates is used at this intensity
powerful enough for 80-90% max intensity
aerobic/anaerobic: carbohydrate oxidation
aerobic
carbohydrate oxidation does this in comparison to anaerobic glycolysis
produces less energy per unit time
aerobic/anaerobic: fatty acid oxidation
aerobic
Time is not important to this aspect of ATP production
capacity
total ATP production of a system or total amount of energy available =
capacity
Capacity from least to most
phosphogen system
anaerobic glycolysis
carbohydrate oxidation
fatty acid oxidation
