MOREIRA, Pedro Vieira Sarmet et al. Análise de equações preditivas da gordura corporal em jovens atletas de “taekwondo”. Rev. Bras. Educ. Fís. Esporte [online]. 2012, vol.26, n.03, pp.391-399. ISSN 1981-4690.

Due to the lack of valid and accessible tests to measure the body fat percentage (BF%) of adolescent taekwondo athletes (TKDA), this study aimed to analyze six anthropometric equations in the prediction of BF% with the Dual-Energy-x-Ray (DEXA) as referential method for fi ve TKDA (12.23 years ± 1.60). The BF% estimated by the equations were compared with DEXA values using the t-student , linear regression and Bland & Altman (B& A) tests. Only the equation of SLAUGHTER et al. (1988) was adequated by the sample size calculation, and although it subestimated the BF% (in 4.85% ± 0.98), it showed a high correlation (R = 0.935; R2 = 0.874 EPE = 1.01) and low amplitude in the limits of agreement at 95% (3.84%) by B&A in comparison to DEXA. However, this equation is adequated to predict the BF% in TKDA, if it’s corrected by the adjustement equation [%G (DEXA) = 1,64 + 1,24 • %G (Eq 4)] generated by linear regression.
