Analysis of the behavior of the body composition measurements by Bioimpedance and DEXA
Athlete, Bioimpedance, Body Composition and Dexa
Objective: To verify the capacity of the different equations proposed by the manufacturer of a bioimpedance in predicting the body composition, when compared to the result of DEXA. METHODS: Thirty-nine men, athletes of the university soccer team, were submitted to body composition evaluation through bioimpedance and DEXA methods. The results obtained were compared between the gold standard, DEXA, and four equations validated and proposed by the bioimpedance manufacturer. Results: The proposed equations did not show significant agreement with the DEXA result. Conclusion: There is a need to develop new equations with the respective group, in order to obtain a more reliable evaluation.
