Introduction The purpose of this lab was to measure resting heart rate and blood pressure as well as during submaximal exercise to see the effects of exercise has on the body. Submaximal graded exercise test is any physical activity whose intensity increases at regular intervals up to but never exceeding 85 percent of an individual’s maximum heart rate. Testing the submaximal level is ideal because all subjects can participate and it is safer. Heart rate is the number of beats per minute measured by either at the radial or the carotid. This gives you the beats per minute which ideally needs to stay around 60-80 BPM. The difference in heart rate between males and females vary. Males tend to have a higher heart rate because they are bigger and it takes more force to send blood throughout their body and the males heart are bigger than a female. Heart rate can also decrease in trained individuals, this is because the heart enlarges and strengthens which leads to larger heart chambers that can pump twice as much blood than an untrained individual. Blood pressure is the measure of heart work or pressure exerted against the walls of the various vessels of the circulatory system by the heart as it pumps blood to the body. This can be measured in mmHg by using a sphygmomanometer and a stethoscope. When measuring blood pressure, you will get two numbers, the first one is the systolic pressure and the second one is the diastolic pressure. The systolic blood pressure measures the
