What is stroke volume?
Volume of blood ejected from the heart per beat
What is heart rate?
Number of heart beats per minute
What is cardiac output (Q)?
Volume of blood ejected from the heart per minute
What is the average stroke volume at rest?
65/70 ml
What is the average heart rate at rest?
70/72 bpm
What is the average cardiac output at rest?
5 litres
What is the trained SV?
80/85 ml
What is a Bradycardia HR?
HR<60 bpm
What is the trained value of Q?
5L
A resting HR below 60 bpm is termed …
Bradycardia
Heart rate plateau reached during constant rate of ………..
Sub maximal work
Aerobic work is where …
O2 supply = muscular demand
The lower the steady - state heart rate …
The more efficient the heart
