Body Fat Validity

The researchers used the Body Mass Index (BMI) categories to classify participants in the study. The study used a two part, multi-variable model, adjusted for age, gender, race, income, education level, and type of health insurance, marital and smoking status (Arterburn, Maciejewski & Tsevat). The results of the survey are as follows:

Thirteen healthy undergraduate students at the University of Brighton (8 males, 5 females; mean ± SD, age: 19.2 ± 1.5 years; body mass: 67.4 ± 16.1 kg; height: 177 ± 28.2m) were briefed with the study procedure. Their anthropometric data was collected, along with a medical questionnaire and their consent to participate in the study. All of the participants were familiar with the laboratory testing procedures.

However, it is difficult to compare body fat percentages, due to the different measurement error associated with each method (Duthie et al., 2003). These limitations lead researchers and coaches to monitor athletes’ body mass and sum of skin folds rather than estimating percentage body fat (Gore, 2000).

The reliability of the BMI depends on the individual’s abilities to accurately measure, calculate and record the BMI. The tools used to measure the patients height and weight should also be checked to ensure they read accurately, for example calibrating

Body composition provides an overall assessment of health and it is important in assessing an individual’s risk of developing diseases such as diabetes, high blood, obesity and some forms of cancer. Body composition indicates the proportion of essential fats and non-essential fats in the body (ACSM, 2012). An optimal health range has been established based on the difference in age, sex, height and weight. Individuals above the established range are at increased risk of developing high blood pressure, diabetes and obesity (ACSM, 2012). While, individuals below the established range are more likely to interrupt the delivery of key vitamins and nutrients to the cells of the body as well as adversely affect the proper functioning of their reproductive

Purpose. The focus of this study is to compare the current practices of obtaining daily weights in the afternoon and evenings, compared to the evidenced based practice recommended in the literature.

Adult overweight and obesity have become a worldwide issue that has very dangerous consequences on health. World Health Organization defines obesity as the “epidemic of the 21st Century”. WHO reports show that 1.9 billion people with 18 years age and older are overweight, and 600 million of them are obese. In the United States, obesity is a serious problem today that results from overconsumption of high-fat food and sugary food with lack of exercise. The Centers for Diseases Control and Prevention reports show that the obesity rates are above 20 percent in all states. Overweight and obesity have become a major public health issue because of their high rates of mortality and morbidity. People who are considered overweight or obese are at increased

The Army’s circumference measuring is the only way authorized to determine a soldier’s body composition. For males it is used by measuring the circumference of the neck and waist and for females it is the waist, neck and hips. Based on soldiers’ height and age their body composition is calculated and compared to a predetermined chart. Many service members including leaders disagree with this method of determining body composition stating it is outdated and inaccurate; however, there are many benefits to using this method as well. This method is beneficial being in the military because it is cost effective, easy to administer, and the least time consuming of most of the other options out there. This way of measuring can be considered inaccurate. It does not directly reflect the body composition of the person being measured especially for individuals who participate in

Obesity rates are soaring throughout North America (What Is Obesity?, 2013). With obesity reaching almost epidemic proportions in the United States, and the threat of a global epidemic, we must watch this alarming increase carefully ( Health Risks of Obesity, 2013). Obesity is defined as: "…an excess of adipose tissue…" (A Report of the Surgeon General, 2014). The two most common measures of obesity are Body Mass Index (BMI is a ratio of weight to height) and relative weight index, such as percent desirable weight (Body Mass Index , 2013). BMI is the most frequently used measure of obesity as it has a strong correlation with more direct measures of adiposity, such as underwater weighing (A Report of the Surgeon General, 2013). Some

Overweight is often misinterpreted as obesity, but it has been proven that individuals such as bodybuilders and professional athletes can be overweight yet they do not suffer from obesity. Obesity refers to just excessive body fat whereas overweight refers to excessive body weight including water, bone, fat, and muscle. A certain amount of fat is needed to store energy, heat insulation, shock absorption, and other functions, but when men reach more than twenty-five percent body fat, and women reach more than thirty percent they are considered obese. A person’s body mass index (BMI) is measured by dividing body weight in kilograms by the square of body height in meters (Wilmore, et al., 2008).

It is a non-invasive method to measure the body composition of the person the premise underlining this procedure is that fat free tissue in the body is proportional to the electrical conductivity of the body. A small electrical current is passed through the body (from ankle to wrist from some units, or from hand to hand or foot to foot) and the impedance of current is measured. The theory underlining BIA is that the lean mass (mainly water and electrolytes) is good electrical conductor, whereas fat is has poor electrical conduction and so it resists the current to pass through.

In fact, if someone is too skinny, they can be classified as malnourished, which can be just as dangerous as being obese. However, having a low BMI does not mean that someone is malnourished or too skinny; they could be a naturally thin person and be perfectly healthy. Health simply all depends on the individual person. Both the volunteers in this study, for example, were very healthy-looking individuals, despite questionable BMI results. In the BIA, Nicole was above the normal body fat percentage; even though her BMI said she was at overweight according to her ideal weight scale. . Frederick was above normal body fat percentage and even above his ideal weight; even though his BMI said he was in the normal range. Females naturally have more body fat, which makes sense about Nicole being over the normal body fat range. However, some of the values could be out of normal range based on the day’s activities. For example, body fat percentage could be higher due to a large lunch before the test. Someone’s total body water could be above the normal range because of drinking an excessive amount of water before the test. There are many factors that affect the accuracy of the BIA

When I think of the body fat measurement procedure used in Part 1 I think buoyancy is something closed to the same scientific research. Where is no device needed to figure out buoyancy because it is scientific research. What buoyancy measure is the objects weight or know mass in water. This is very important to know the process for buoyancy because of the costal shipping industries. Ship builders need to use the scientific research in determining the buoyancy because is it an essential tool for measurement of the shipping requirements. The standardized measurement of determining buoyancy improves the measurement practices in the shipping industries as well in the art of scuba diving or free diving. The reason standardized measurement

This is a laboratory report on measuring body composition. The aim of the laboratory report was to compare two different field methods skinfolds and bioimpedance analysis to measure body composition and evaluate the most reliable doubly indirect method to measure body composition. A number of studies such as Kitano,T have shown a strong correlation between skinfold and bioelectrical impedance analysis and tend to have an average body fat difference of less than 0.6.
