Training at altitude

Question 1

Explain cardiovascular drift

Answer 1

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

Question 2

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

Answer 2

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

Question 3

Explain the advantages of altitude training

Answer 3

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

Question 4

Describe some of the negative affects of altitude training

Answer 4

Benefits lost within a few days of returning back to sea level
Time away from family
Altitude sickness

Question 5

Describe the term ‘train low recover high’

Answer 5

Training at sea level and recovering in high altitude conditions using things such as hypoxic tents

Question 6

Describe ‘cardiovascular drift’

Answer 6

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

Question 7

What is the optimum temperature of the body

Answer 7

36-38 degrees

Question 8

What is isotonic contraction

Answer 8

Where the muscle changes in length while tension increases the mains constant
