Introduction Your body is made up of six very important nutrients: Water, Fat, Protein, Carbohydrates, and other vitamins and minerals. When dealing with one’s health, there are many factors that can influence one’s body weight. Although weight is not always the best indicator of one’s health, there are ways to determine healthy body composition. The tool is called bioelectric impendence analysis (BIA). Another way to determine one’s body composition is by figuring out one’s body mass index (BMI). To find out your BMI, you take you divide your weight by you height squared then multiply it all by 705. These methods will give you a better understanding of your overall body composition. Three different types of mass make up your body’s mass: lean mass, fat mass, and water mass. You can take this information and break it down further by calculating the percentages of fat, body cell mass (BMC), extra curricular mass (ECM), total body water (TBW), and intercellular water (ICW). These are much better indicators of one’s health than just simply taking their body weight. Fat has a total density of .9g/ml and is the energy storage for the body. This is equal to the person’s actual mass minus the fat free mass. Body cell mass is the portion of the body where the work is done. The body cell mass contains about 98-99% of the body’s potassium, which is needed to maintain the
body’s water balance. While performing BIA you must send a mild electrical current through the body that can connect body changes in resistance and capacitive reactance. The amount of resistance directly correlates with the amount of water and conductive electrolytes of the minerals in the body. To calculate BMI you must use a formula to asses your body weight relative to your height. Although this procedure does have some limitations, it is very useful because it gives a strong connection with body fat in most individuals. Wt (lbs.) / Ht (in) ² x 705. BMI values less than 18.5 are considered underweight. BMI values from 18.5 to 24.9 are healthy. Overweight is defined as a body mass index of 25.0 and over (7 Obesity is a major problem in the United States. Of 39.8 American adults more than 57% of them are obese (2). Obesity leads to many other diseases like coronary heart disease. Coronary heart disease is the number one cause of death for American adults. This can be prevented by having a healthy diet, exercising, minimizing stress, and by refraining from smoking. The Queen’s College Three-Minute Step Test is a test used to evaluate the increased cardiovascular or cardio respiratory need. The participant will step up and down on and off of blocks for three minutes. After the three minutes are up the participants will take their pulse and their heart rate directly correlates with their VO2 level VO2 is an expression of an athlete’s ability to consume and utilize oxygen.

Methods In this lab we first started off by weighing ourselves on the scale. Then we measured our height and went and recorded our data in our lab manual.
