Body Composition Lab Report

The World Health Organization (WHO) defines body mass index (BMI) as a simple index of weight-for-height that is commonly used to classify overweight and obesity. To determine BMI, a person’s weight, in kilograms, is divided by the square of the person height in meters

Introduction: In this experiment, cardiovascular fitness is being determined by measuring how long it takes for the test subjects' to return to their resting heart rate. Cardiovascular fitness is the ability to "transport and use oxygen while exercising" (Dale 2015). Cardiovascular fitness utilizes the "heart, lungs, muscles, and blood working together" while exercising (Dale 2015). It is also how well your body can last during moderate to high intensity cardio for long periods of time (Waehner 2016). The hypothesis is that people who exercise for three or more days will return to their resting heart rate much faster than people who only exercise for less than three days.

Introduction Muscle is formed with a long and thin tissue called muscle tissue which moves the organs and organisms, and the muscle tissue is made out of a group of cells called the muscle fibers. There are three types of muscle: skeletal muscle, smooth muscle, and cardiac muscle. Skeletal muscle is the muscle who moves the bones, it has much longer fibers than the smooth muscles. Smooth muscle forms the walls of organs, for example, the wall of a stomach. Cardiac muscle is the muscle that forms the heart. From the cross-section view of a muscle, it shows that there is a layer of muscle sheath around the outermost layer of the muscle. The blood vessels that brings glucose and oxygen to the muscle are weaved in the fibers, and there is a layer of epithelial cells around the muscle to keep the fibers together.Muscle tissue can repair itself, but with round scar tissue instead of long, stretchy fibers. Skeletal

1.0. INTRODUCTION The primary function of the digestive system is to transfer nutrients, water, and electrolytes from the food consume into the body’s internal environment. The ingested food is essential as an energy source, or fuel, from which the cells can generate ATP to carry out their particular energy-dependent activities such as contraction, transport, synthesis, secretion and even renewal of body tissues. Three primary categories of food ingested by humans which are carbohydrates, proteins and fats emerge as large molecules. These large molecules cannot cross plasma membranes intact to be absorbed from the lumen of the digestive tract into the blood or lymph; hence, it must undergo degradation in size (Sherwood, 2013). This

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

The Army Body Composition Program (ABCP) relies on a basic form of body circumference measurements to determine a soldier’s body fat composition. Many people believe this standard of measuring is an unfair and inaccurate representation of their true body composition. There are several options that could provide a more accurate

Body fat distribution can be estimated by skin fold measures, waist-to-hip circumference ratios, or techniques such as ultrasound, computed tomography, or magnetic resonance imaging.” (www.cdc.gov) The difference is that obesity is a definite problem, whereas being overweight can be directly related to obese but may just be that your lean muscle weight is higher than the average person in you height category.

Statistics uses math to determine whether or not an experiment happened by chance. In other words, it determines the probability of your results being by chance or if it is factual data. The mathematical ways of determining probably include looking at mean, standard deviation, mode, and median. This experiment will use statistics to test the probability.

From the calculations in the data analysis, the actual percent composition of magnesium is 65.3% ± 1.7%, the actual percent composition of oxygen is 34.7% ±2.5%. The purpose of this lab was achieved as the percent composition of the magnesium oxide was determined and was used to test the law of definite proportions. The hypothesis was mostly correct as the results demonstrated that the actual percent composition was only slightly greater/lesser than the hypothesized percent composition. However, the actual percent composition may have been affected by several limitations during this investigation.

The experimental procedures for Lab 2 were provided on Blackboard labelled as “Pre-Lab 2: Techniques & Measurement”.

The first error noticed is the fact that we measured everything with a small measuring tape instead of a big measuring tape, which didn’t help since we were taller and bigger than the measuring tape, so we had to use two measuring tapes added together. Using a small measuring tape to find out these measurements ended being extremely inaccurate. After data collection we were not really sure if the numbers we got were real, and it probably affected a lot on the way the results came out. The lab activity validity started to be questionable now.

MethodsThe activities which I have taken on for my practicum have included, assisting carrying out them-NEAT evaluation at various locations around Hurlburt Field; creating nutritional informationpackets for various squadrons participating in the m-NEAT assessment; participating in theorientation briefings for new airmen and new to Hurlburt officers; distributing OperationSupplement Safety (OPSS) information; conducting InBody Body Composition assessments;providing gait analysis evaluations; and assisting with nutritional briefings. The priority of mypracticum is assisting the health professionals at the HAWC with the m-NEAT assessment.

Introduction: Exercise is a physical activity or particular movement that is used in order to become healthier and stronger. (1) Exercise, in all of its forms, has various effects on the different systems in the human body. One of the main benefits is cardiovascular health, including circulation and heart health. Exercise uses a lot of energy, which the cells derive from oxidising glucose. Meaning that the heart has to work harder to pump more blood throughout the body and the heart has to beat faster in order to achieve a high effort. (2) The heart benefits from exercise include being able to pump more blood through the body and continue working at a higher level with less strain. (3)

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.

INTRODUCTION: Carbohydrates are the product that made up from carbon, hydrogen and oxygen. Carbohydrates are form by the combination of carbon dioxide and water molecules. The carbohydrates contain two specific functional group in it which is the hydroxyl groups and carbonyl groups.A reducing sugar is a type of sugar with is an aldehyde group.This means that sugar can act as a reducing agent.The procces of reducing sugar is isomerisation,example of reducing sugar islactose,maltose,glucose and fructose.All monosaccharides are capable of reducing other chemicals such as copper (II) sulphate to copper oxide.Beside that disaccharides such as maltose and lactose are reducing sugar,however sucrose is non reducing
