Universidad de Zaragoza Comparison Of Body Composition Methods For The Assessment Of Body Fat In Adolescent Soccer Players 2016 Access copy available to the general public Unrestricted Anthropometry, dual energy x-ray absorptiometry (DXA) and air displacement plethysmography (ADP) are widely used for assessing body fat percentage (%BF). The accuracy among body composition methods in different kind of populations such as children, adults, obese persons, and athletes has been studied but there are some discrepancies between them. PURPOSE: To compare %BF assessed by DXA, ADP and anthropometry in adolescent soccer players. METHODS: %BF was assessed in ninety-two soccer players (64 males, 13.3 ± 0.5 y; 28 females, 13.3 ± 0.6 y) by anthropometry, DXA and ADP. Anthropometry measurements were registered following the recommendations of the ISAK. Anthropometry %BF was calculated using the equation proposed by Slaughter et al for adolescents. ADP %BF was calculated with 3 different formulas: (i) the general Siri equation (ADPSiri); (ii) the age- and sex-specific equation by Lohman (ADPLohman) and (iii) the age- and sex-specific equation by Silva (ADPSilva). Agreement and differences between methods were assessed by two-paired samples t tests and calculating the 95% limits of agreement. RESULTS: In the whole sample, ADPSiri ADPLohman ADPSilva and anthropometry underestimated %BF by 2.0, 6.9, 6.2, and 6.0% respectively compared to DXA (all p<0.05). The 95% limits of agreement ranged from ±5.91% to ±10.78%. Similar results dividing by sex were found. CONCLUSION: Although the 3 used methodologies have been several times described as valid for the assessment of %BF, based in our data it seems that ADP, anthropometry and DXA are not interchangeable for the assessment of %BF in adolescent soccer players. info:eu-repo/grantAgreement/ES/MEC/AP-2012-02854 info:eu-repo/grantAgreement/ES/MINECO/DEP2012-32724 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 4.141 2016 SPORT SCIENCES 6 / 81 = 0.074 2016 Q1 T1 2.052 2016 Orthopedics and Sports Medicine 2016 Q1 Sports Science 2016 Q1 Physical Therapy, Sports Therapy and Rehabilitation 2016 Q1 info:eu-repo/semantics/conferenceObject info:eu-repo/semantics/publishedVersion (orcid)0000-0002-0137-9900 Lozano-Berges, G.
