Document Summary
The effect body composition information, has on people. Understanding body composition: semantics/words; use adipose tissue, emotions elicited; anxiety/frustration/discouragement/bad feelings. We have done studies of grade-school girls, and even in grade 1, girls think the culture is telling them that they should model themselves after celebrities who are svelte . Those girls were shown to have the highest body esteem. People who think its great to eat nothing. Maintaining healthy body composition is difficult for most people. Quantity of amount of foods with high fat becomes the issue. Energy storage, protection (physical and cold), maintain serum lipids, vitamin storage, burn fat (thermogenesis) If not drinking enough, adipose tissue will be high: drink water- %bf will be lower. Errors in collection (mm of skin folds) Measure error and biological variability: standard error of the estimate, represents a range where there is a 68% probability for the true value to be located. Importance of precise measurement: within the numbers there is truth.
