Training at altitude Flashcards

1
Q

Explain cardiovascular drift

A

Cardiovascular drift starts after 20mins
Fluid lost from blood as sweat
Blood becomes more viscous
SV decreases so HR increases

Q

Explain the effects of altitude on the respiratory system and cv system

A

A DECREASE IN PPO2 IN ATMPSPHERIC AIR LEADS TO DECREASE PPO2 IN THE ALVEOLI

DECREASES PO2 CAUSES A REDUCTION IN THE DIFFUSION GRADIENT

LEAD TO LESS AFFINITY BETWEEN 02 AND HB

DECREASED 02 TRANSPORT IN BLOOD

BR TO COUNTER THE ISSUES OF HYPOXIC CONDITIONS, HEART AND BREATHING RATE WILL BE ELEVATED AS THE BODY STRIVES TO DELIVER 02 TO THE MUSCLES \ ORGANS

Q

Explain the advantages of altitude training

A

Low pp of PP02

EPO hormone is stimulated to produces more HG to carry as much 02 as possible

Increased oxygen carrying capacity

Leading to a higher aerobic performance
And ability to work harder without producing as much lactic acid

Q

Describe ‘cardiovascular drift’

A

The viscousity of blood increasing due to the loss of blood plasma as a result of sweating to regulate temperature
This results in HR having to increase as SV decreases
This usually occurs 20minutes after excercise
