There is increased value in twain the systolic and diastolic slant pressure and heart rate. The result regarding the blood pressure is consistent with opposite researches (Kelley & Kelley, 2000) which indicated that there is a progressive increase both the systolic and diastolic pressure. The result regarding heart rate is similarly consistent with several studies (Arroll & Beaglehole, 1992) which indicated that there should be an increase in the heart rate later exercise.
