Letters to editor: Anaerobic Performance in Obese Populations: Underestimation of Power Profiles

We read with interest the article recently published in the september issue of the asian journal of sports medicine by loenneke et al[1]. we were particularly interested in the section that stated; ‘the bia device investigated in this study did not provide a valid estimate of fat free mass index (ffmi) in male and female collegiate athletes. although there was a general tendency for the bioelectrical impedance analysis (bia) to underestimate ffmi compared to dexa, 98% of the estimates were within plus or minus 2 kg/m². therefore, while slightly biased, bia may provide a reasonable (± 2 kg/ m²) estimate of nutritional status for practitioners who are unable able to afford more expensive equipment’.
