Currently, one of the most accurate measurements of body composition components, including the fat content of the body is based on the method of dual X-ray absorptiometry (DEXA). The application of the DEXA method in clinical setting is usually limited to the assessment of bone health status due to the device’s cost and immobile nature, therefore in sport diagnostics the body composition estimation is usually carried out with other methods, such as bioimpedance analysis or anthropometrical methods based on the measurement of body dimensions, which ensure a rapid, accurate and frequently repeatable way of examination. For our research goal we choose the comparison of the most frequently used body fat percentage estimation methods. The accuracy of the other methods in the light of the DEXA estimations is presented. Sport Sciences and Diagnostic Research Centre of the Hungarian Handball Federation coordinated the assessment of 171 young elite handball players (14-21-year-olds), whose body composition estimations were performed in the spring and summer of 2023. The preliminary analysis of body fat percentage estimates in handball players carried out with different methods showed that the rapid and cost-efficient estimations based on anthropometric skinfold measurements can substitute the body fat percentage estimation method based on the clinically acclaimed golden standard dual X-ray absorptiometry technology. Body fat percentage estimation via InBody 770 device showed significantly lower values compared to the DEXA method, however this difference was consistent, therefore body composition assessment via InBody device can serve as an alternative of monitoring personal progress and status. We also carried out examinations with a novel ultrasound technology aided by BodyMetrix device, its subcutaneous fat thickness measurement estimated accurately the skinfold thicknesses on human body, its body fat percentage estimation based the skinfold thicknesses was adequately accurate compared to the DEXA method. With the aid of available DEXA measurement results and with the aim of creating an alternative method with low instrument requirement for body fat percentage estimation, which can be used with the highest accuracy particularly considering the body composition of young elite athletes, we created a modified sport-specific body fat percentage estimation equation. Our new estimation method was based on classical anthropometric skinfold measurements, and it accurately correlated with the DEXA body fat% estimates in case of young elite handball players.
