Assignment 5- Body Composition
1. Measure your weight and height on an accurate scale. Calculate BMI as follows:
BMI = Weight in kg / Height in m2
2. Record your data below:
Name:
Gender:
Age:
Height in inches:
Height in meters (meters = inches x .0254)
Square the answer above for meters squared:
Weight in pounds:
Weight in kg (kg = pounds / 2.2):
BMI:
3. Because we are a distance education section of KINE 1000, you do not have access to a skinfold assessment or bioelectrical impedance analysis to determine your body composition (% body fat). While BMI does NOT indicate body composition (only weight relative to height), we can use BMI (along with other predictive factors like age and gender) to ESTIMATE your body composition. Estimate your percent fat from the following equation:
Percent fat = (1.46 x BMI) + (0.12 x age) – (11.61 x gender) – 10.02
Note: Age is in years; and for gender male = 1, female = 0
4. Record your results from #2 and #3 below and indicate how your values are classified (find the “optimal range” of fat for your age and sex in Table 7.2 on p. 37).

5. When using BMI to estimate percent fat, body composition is not considered. Thus, this test does not provide an accurate estimate of percent fat for everyone (for those who have high muscle mass). Do you think the test was accurate for you? Why or why not?
