- Title
TOTAL-BODY PRESSURE MAPPING FOR THE ASSESSMENT OF BODY COMPOSITION.

- Abstract
Several methods of assessing body composition in human beings have questionable reliability and validity. Further, some of them are difficult and/or costly to perform, and may be poorly tolerated by participants. Total-body pressure mapping (PM) is a new method used to assess body composition. This method requires that subjects lie in a supine position on a mattress-sized mat containing a matrix of pressure-sensitive transducers. Data from this mat are used to estimate fat mass (FM), fat-free mass (FFM), and percent body fat. The purpose of this study was to examine the test-retest reliability and validity of PM when compared with criterion values from Dual Energy X-ray Absorbtiometry (DEXA). Twenty seven participants (18 male and 9 female) between the ages of 19 and 24 years were evaluated with PM and DEXA for FM, FFM, and percent body fat. The test-retest intraclass reliability coefficient for PM sensor data was .979. Pearson Product-moment correlation coefficients for FM, FFM, and percent body fat between PM and DEXA were .929, .958, and .872 respectively. The PM method was quick (under 1 second per scan), reliable, valid, easily performed, and well tolerated by all participants. The results of the present study support the need for future research where intricate pressure patterns in a variety of body positions can be tested on multiple populations.
