Name: Kai Chen Course Name: Issue in Biology Date: 18/10/12 Professor: Jay Wildt Assignment: Lab Report 1 The relationship of cardiovascular fitness and aerobic exercise by Pulse Rate Test between Athletes and Non-Athletes Introduction: The lab experiment one is going to use pulse rate test to test the difference between people who has physically fit and less fit, to figure out whether the cardiovascular fitness can be determined by measuring a person’s heart before and after aerobic exercise. A physically fit person such as athletes should have a relatively slower pulse rate after exercise than non-athletes. The aerobic is means `with oxygen,' when people doing aerobic exercise, the muscles will require to use oxygen from the blood (Gilliam, 2002). The pulse is the heart beats rate, so it is also called heart rate, which is the total times the heart beats every minute (bpm) (Chernecky and Berger, 2004). The subjects of experiment are Athletes and Non-Athletes, which is compare of a person who works out a lot and who are not works much. The aerobic exercise always use a lot of oxygen, one of the functions of blood is to deliver oxygen, in order to deliver more oxygen, the heart will beat faster to make more blood ( Brain , 2007). Because of athletes always have a lot of aerobic exercises, so theirs heart are trained stronger than normal person. This lab report will use the alternate hypothesis, which assumes that there is an
