What is cardiovascular drift?
Characterised by a progressive decrease in stroke volume and arterial blood pressure, with a progressive rise in heart rate after 10 minutes of exercise in a warm environment.
1 of 10
What causes cardiovascular drift?
When we sweat, a portion of the lost fluid volume comes from the plasma volume. Reduced plasma volume, reduces venous return and stroke volume.
2 of 10
Why does heart rate increase?
To compensate and maintain a higher cardiac output in an attempt to create more energy to cool the body down.
3 of 10
How can you minimise cardiovascular drift?
Maintain high fluid consumption before and during exercise.
4 of 10
How long does it take for cardiovascular drift to to occur?
10 minutes of exercise.
5 of 10
What environment is needed for cardiovascular drift to occur?
A warm environment.
6 of 10
What fluid is lost and how?
Plasma through sweating.
7 of 10
Why does cardiac output increase?
More energy is needed to cool body/sweat.
8 of 10
What increases during cardiovascular drift?
Heart rate and cardiac output.
9 of 10
What reduces during cardiovascular drift?
Stroke volume, plasma volume and venous return.
