Blood flowing through the vessels exerts pressure on the walls of these
vessels. This pressure is called blood pressure and is measured by the number
of millimeters that the blood causes a column of mercury to rise. We need two measurements
of pressure to identify the force of the blood flow: the pressure when the
heart beats and the pressure when it is resting between beats. The first is
called systolic and second diastolic. Typical resting systolic and diastolic
blood pressures are 120 and 80 mm Hg respectively.

Effects of training on stroke volume
Stroke volume is termed the amount of blood that is pushed out of the
ventricles of the heart with each beat.
A normal range of values at rest is between 60 and 130 ml per beat.
These amounts can increase to between 150 and 180 ml per beat during exercise.
These values refer only to the blood that is pumped out of the left ventricle.
An equal amount of blood will simultaneously be pumped out of the right
ventricle.
