Abstract
Duel digital-photograph anthropometry (DDPA) is a new development of potential value in the assessment of human total body volume (TBV), body composition and circumference measurements. Initial research with this method used lung volume assessments [functional residual capacity (FRC)] when creating regression formulas for the prediction of TBV. PURPOSE: To assess the benefit of FRC measurement inclusion in TBV regression formulas. METHODS: Healthy female adults (n = 18) (age 22 to 51) were evaluated for TBV by DDPA and hydrodensitometry from a single tester. FRC was measured using an oxygen dilution method. Results of regression analyses both with and without FRC are presented in the table below. RESULTS: Stepwise linear regression analysis indicate that the inclusion of FRC calculations do not significantly improve predictions of TBV when using DDPA. CONCLUSION: Exclusion of lung volume assessments from the DDPA protocol will substantially reduce the cost and time of testing while making the evaluations more comfortable and convenient for subjects.Table: No Caption Avilable
