aperson's bloos pressureis measured before and after exercise.what would u expect the activity to have on the systolic blood pressure?on diastolic blood pressure?explain.

The systolic arterial pressure is defined as the peak pressure in the arteries, which occurs near the beginning of the cardiac cycle; the diastolic arterial pressure is the lowest pressure (at the resting phase of the cardiac cycle). The average pressure throughout the cardiac cycle is reported as mean arterial pressure; the pulse pressure reflects the difference between the maximum and minimum pressures measured.

Typical values for a resting, healthy adult human are approximately 120 mmHg (16 kPa) systolic and 80 mmHg (11 kPa) diastolic (written as 120/80 mmHg, and spoken as "one twenty over eighty") with large individual variations. These measures of arterial pressure are not static, but undergo natural variations.

For example, after doing  exercise  the pressure may increase by 15-20mmHg

systolic from 80 ---------> 90/95 mmHg

distolic from 120 --------> approx 130 mmHg
