Body Composition

  1. 1. Body Composition<br />Ideal<br />Non-Ideal<br />
  2. 2. Obesity<br />Obesity is defined as the accumulation of excess fat for one’s age and body type which is determined by hydrostatic weighing or skin fold measures.<br />Ideal Body Fat % For College Students:<br />Men 11-15%<br />Women 18-22%<br />Men with 23% and Women with 28% are considered in the Obese category<br />
  3. 3. Ideal Weight Based on Height<br />For Women For Men<br />
  4. 4. Problems With Charts<br /><ul><li>People place far too much emphasis on charts
  5. 5. Experts would rather people not look at their actual weight
  6. 6. Body weight does not tell us what is really important
  7. 7. How much body fat the person has and how fit they are.
  8. 8. Non-Caucasians are underrepresented
  9. 9. Age is not considered
  10. 10. Desirable weights are too high for young people and too low for elderly
  11. 11. They only are accurate for mid age people</li></li></ul><li>Body Fat Percentages<br />Adipose tissue is fatty tissue <br /> -Most fatty tissue lies right under the skin<br />When looking at goal setting you should look at the amount of fat that you have not your body weight <br />One simple way to measure body fat is to pinch certain areas<br />
  12. 12. Determining Body Mass Index(BMI)<br />Body Mass Index provides a ratio between body weight and height and is quickly becoming the standard way that we define obesity.<br />Federal guidelines suggest that we keep BMIs under 25.<br />BMI 19-25 <br />desirable; minimal and low risk<br />Pay attention to diet, increased physical activity and lifestyle changes.<br />BMI 26-29 increased health risk; moderate risk<br />All of the preceding and a low calorie diet(800-1,200 calories daily)<br />BMI 30-40 Obese; high and very high risk<br />All of the preceding, drug therapy, and a very low calorie diet<br />BMI over 40 Extremely Obese; extremely high risk<br />All of the preceding and surgery<br />
  13. 13. Problems with BMI<br /><ul><li>The test incorrectly classifies 5-10% of the population as overweight or obese.</li></ul>Such as:<br />Muscular athletes 6 foot 190 pounds or 6-foot-1, 220 are labeled as overweight or obese<br /><ul><li>Overestimates the relationship between overweight and health when what creates the health problems is body fat. </li></ul>When you are looking at how to lose weight you should focus on body fat not overall body weight.<br />
  14. 14. Other Tests Used to Determine Weight<br />Electrical impedance is a quick and fairly accurate means of determining an individual’s percentage of body fat that uses electrodes attached to the wrists and ankles to determine the percentage electronically.<br />Hydrostatic weighing is a method of measuring body fat by submerging an individual in water.<br />
  15. 15. Weight Loss Vs Fat Loss<br />Typical Diet with no aerobic exercise and strength training may result in fat loss of only 6-7 pounds but also a loss of 2-4 pounds of lean muscle tissue<br />Ideally we want a fat loss without a loss of lean muscle tissue.<br />Many dieting fads may lose 2-3 pounds per week, but the main problem is that they are losing lean muscle mass and not fat. When the weight is gained back the weight is fat not muscle <br />Which will result an uneven fat to muscle ratio that is unhealthy for the body.<br />
  16. 16. For Activity<br />Use two of the methods discussed to determine your Body Composition to be turned in next time.<br />Information on how to do each method can be found in the book<br />
