Training at altitude Flashcards
Explain cardiovascular drift
Cardiovascular drift starts after 20mins
Fluid lost from blood as sweat
Blood becomes more viscous
SV decreases so HR increases
Explain the effects of altitude on the respiratory system and cv system
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
Explain the advantages of altitude training
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
Describe some of the negative affects of altitude training
Benefits lost within a few days of returning back to sea level
Time away from family
Altitude sickness
Describe the term ‘train low recover high’
Training at sea level and recovering in high altitude conditions using things such as hypoxic tents
Describe ‘cardiovascular drift’
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
What is the optimum temperature of the body
36-38 degrees
What is isotonic contraction
Where the muscle changes in length while tension increases the mains constant
