Importance of aerobic (mitochondrial) enzyme activity during endurance performance Flashcards
(14 cards)
What is a strong predictor of aerobic endurance?
Maximal oxygen consumption
What affects maximal oxygen consumption?
Aerobic enzyme activity
How is ATP generated?
Through oxidative phosphorylation
What decrease your chance of death?
Increase VO2max
What happens to aerobic capacity as we age?
It declines
What happens to mitochondria number as we age?
It declines
What does the decrease in mitochondria impact?
ATP production via oxidative phosphorylation
What is reduction in performance associated with age most likely due to?
A reduction in mitochondria number
What allows us to infere how many mitochondria are in a muscle?
The DNA as each mitochondria has its own DNA
How can we discover the mitochondria concentration?
Measure the enzyme that occurs in the electron transport chain
What is mitochondrial biogenesis?
Term used to describe the adaptive response for f mitochondria to physiological stimuli
What does complete mitochondria biogenesis represent and increase?
Number
Function
Capacity
-represents an expansion of the mitochondrial reticulum
How can we measure mitochondrial biogenesis?
Altered green
Protein
Enzyme
Synthetic rates
What is a potent stimulus for skeletal muscle mitochondrial biogenesis?
Exercise
