what increases most after exercise-systolic or diastolic pressure?
You systolic will increase more than diastolic. This is because the heart is working very hard during the exercise and will pump extra blood with each beat as well as increasing the heart rate. Natually this will increase both the diastolic and the systolic. However, with excercise, many blood vessels in the muscle are dialated. That reduce the peripheral resistance and will reduce blood pressure, especially the diastolic.
