What is Stroke volume |
The amount of blood pumped out of the left ventricle of heart in a single contraction |
|
|
How is stroke volume effected by aerobic training |
An increase in stroke volume, more blood pumped around the body per contraction |
|
|
Cardiac output |
Amount of blood pumped out of the L- ventricle per minute |
|
|
How is cardiac output calculated? |
Stroke volume (SV) X Number of beats per minute (HR) = Cardiac output (CO) |
|
|
How is CO effected by training |
Increase in cardiac output, heart pumps more blood around the body at any HR, decrease in resting HR |
|
|
What is haemoglobin |
Responsible for the transport of oxygen, CO2 binds to haemoglobin then delivers to the working cells |
|
|
How does training affect haemoglobin level |
Increases level of haemoglobin per millilitre of blood, meaning each ML of blood is delivering more oxygen |
|
|
Oxygen uptake |
The body’s ability to absorb oxygen into the blood, transport the oxygen, then transfer it into the muscle |
