A comparison of fat mass and skeletal muscle mass estimation in male ultra-endurance athletes using bioelectrical impedance analysis and different anthropometric methods. For the determination of muscle and fat mass, there are very elaborate methods such as MRI, Dexa or underwater weighing. Ann is very simple and practicable methods such as the determination of the skin fold thickness and bioelectric impedance analysis (BIA). We compared the practically simple methods of skin fold thickness and Bia with more than 200 men.
We came to the conclusion that the methoders of the BIA both the muscle and fat mass overestimated and less reliable appears as the simple method of skin fold thickness. The whole work can be found under https://pubmed.ncbi.nlm.nih.gov/22411391/
