V02 max and obla Flashcards
What is v02 max?
The maximum amount of oxygen that can be taken in and used per minyre
What physiology effects?
Hypertrophy- bigger heat»_space; sv
increase sv increases haemoglibin increase in o2 to muscles
» my glob in
»capillary density increase in capillaries meaning increase in vasodilation to muscles
twitch fibres- slow twitch fibres better vo2
What are the gender factors?
males have a higher vo2 naz
How does lifestyle?
Methods of training- Fartleks training increase vo2 adaptations
endurance
smoking- decreases alveoli less gas exchange
What is lactate threshold?
When performer uses lactic acid system
What is lactate tolerance?
The amount of lactic acid the athlete can take - stops
What happens when athletes untrained?
Athlete reaches obla at 50% vo2 max
Athlete uses obla at half
What happens with a trainer athlete?
accumulate lactic acid at 75% vo2 max and can use buffering capacity to remove it with a high bp2 max
