Abstract: The aim of this study was to examine the validity of two types of OMRON body composition analysers (BF 511 and VIVA) in comparison with the InBody 270 body composition analyser, in karatekas. The measurements were performed during the summer national camp of the FUDO-KAN Karate Federation, and the sample of subjects included 20 men and 27 women (Age = 16 ± 5.99 years; Body height = 158 ± 14.13 cm; Body mass = 51 ± 17.29 kg), and the following body composition variables were used: body mass (BM), body fat percentage (%BF) and skeletal muscle mass percentage (%SMM), which were estimated using all three body composition scales. Pearson correlation coefficient (r) and the coefficient of determination (r2) were used to determine the validity of both OMRON body composition analysers. A high correlation of BM InBody with BM OMRON (BF 511 – r 0.99, r2=0.99; VIVA – r=0.99, r2=0.99), %BF InBody with %BF BF 511 (r=0.92, r2=0.84), and %BF InBody with %BF VIVA (r=0.63, r2=0.40), %SMM InBody with %SMM BF 511 (r=0.68, r2=0.46) were observed. The results obtained indicate that there are certain deviations, especially when it comes to assessing skeletal muscle, when compared with the InBody 270 body composition scale.
