Body Fat Test
The objective of this test is to monitor the athlete's level of body fat.
To undertake this test, you will require:
How to conduct the test
The fat-free body mass (FFBM) represents the body mass devoid of all fat whereas lean body mass (LBM) contains a small percentage of essential fat. For men Behnke (1953) considered it to be FFBM+3% essential fat and for females FFBM+12% fat (3% essential fat + 9% sex-specific essential fat).
The density of fat and fat free tissue remains relatively constant: fat = 0.9 grm/cm³ and fat free tissue = 1.1 gm/cm³.
Analysis of the result is by comparing it with the results of previous tests. It is expected that, with appropriate training and diet between each test, the analysis would indicate an improvement in the athlete's percentage body fat.
This test is suitable for everyone but not for individuals where the test would be contraindicated.
Test reliability refers to the degree to which a test is consistent and stable in measuring what it is intended to measure. Reliability will depend upon how strict the test is conducted. The following link provides a variety of factors that may influence the results and therefore the test reliability.
Test validity refers to the degree to which the test actually measures what it claims to measure and the extent to which inferences, conclusions, and decisions made on the basis of test scores are appropriate and meaningful. This test provides a means to monitor the effect of training on the athlete's physical development.
The test is not a good predictor of percentage body fat; however, it can be used to indicate changes in body composition over time.
