Oxygen uptake at rest, during exercise and recovery Flashcards
(11 cards)
Whilst resting, the demand for oxygen is?
LOW- with heart rate, respiratory rate and muscle activity also being low
what is steady state?
when oxygen supply is able to meet oxygen demands
what is oxygen deficit?
A period, typically at the beginning of exercise, when oxygen demands are greater then oxygen supply
what is EPOC?
Excess Post-exercise Oxygen Consumption.
at the completion of exercise, oxygen consumption remains elevated
what is the fast phase of EPOC?
happens in the first 2-3 minutes after exercise. ATP is restored at the muscles, oxygen is restored to myoglobin and CP is resynthesised
What is VO2?
Volume of oxygen consumed by the body per minute.
what is VO2 MAX?
The maximum volume of oxygen the body can take in, transport, and use during intense exercise.
Reflects aerobic fitness.
what is absolute VO2 max?
the total amount of oxygen you breath in (not dependant on weight)
Used to compare individuals regardless of size.
What is relevant VO2 max?
the amount of O2 you inhale relative to your body weight.
Accounts for body weight, allowing fair comparison between people of different sizes.
What factors affect oxygen uptake?
-body size
-gender
-genetics
-age
-training or fitness status
what is the Slow phase of EPOC?
Lasts for the remainder of recovery. Involves the gradual return of core temperature, heart rate, and respiratory rate to resting levels, recovery of body systems (especially muscular), conversion of lactic acid into glycogen, glucose, and protein, increased fat metabolism, and the oxidation of hydrogen ions.
