Stroke Volume
Stroke volume is blood pumped per heartbeat, rising with aerobic fitness. Better stroke volume means lower heart rate at the same endurance pace.
Stroke volume is how much blood the heart ejects per beat—rising with aerobic fitness so heart rate stays lower at the same pace. Endurance base training expands stroke volume over months; dehydration and illness shrink it acutely.
It pairs with heart rate to determine cardiac output.
Common questions
-
How do you improve stroke volume?
Months of mostly easy aerobic volume, adequate hydration, and recovery—not all-out intervals every session. Re-test pace at a fixed submax heart rate every four to six weeks.
