Hypothesis: Exercise can raise the blood pressure and the pulse rate.
Aim: To determine the effect of exercise on the blood pressure and the pulse rates of students in the class.
Introduction: The blood pressure of a person is the force exerted by the blood on the walls of the arteries per unit area. The blood pressure unit is mmHg. The blood pressure of an individual is expressed in two ways, the systolic (due to the contraction of the ventricle) and diastolic, (due to the relaxation of the ventricle). The normal blood pressure of an individual is 120/80 (systolic / diastolic). Various factors can alter a person's blood pressure; this includes exercise, smoking, stress, diseases and age.
