Abstract

This review examines gold standard densitometry-based methods for assessing body composition, focusing on hydrostatic weighing (HW) and air displacement plethysmography (ADP). Both techniques estimate body density to predict fat-free mass and fat mass. The review outlines the principles and procedural steps of each method while discussing their validity, reliability, and limitations. The accuracy of HW is strongly influenced by standardized underwater maneuvers and accurate residual volume determination. ADP, on the other hand, is highlighted for its practicality and minimally invasive nature. However, both methods can yield measurement errors due to individual physiological differences. It is emphasized that standardizing measurement procedures and integrating multi-compartment models can improve accuracy in body composition analysis. Overall, HW and ADP remain valuable tools in both research and clinical applications for evaluating health and physical performance.

Vücut Kompozisyonu Belirlenmesinde Altın Standart Densitometri Teknikleri Kullanımı

Abstract

Bu derleme çalışmasında, vücut kompozisyonunun değerlendirilmesinde kullanılan altın standart densitometri temelli yöntemler olan hidrostatik tartım (HT) ve hava yer değiştirme pletismografisi (HYDP) ayrıntılı olarak ele alınmıştır. Her iki yöntem de vücut yoğunluğunu esas alarak yağsız kütle ve yağ kütlesinin tahmin edilmesini sağlar. Çalışmada, bu yöntemlerin ilke ve uygulama basamakları açıklanmış; geçerlik, güvenilirlik ve sınırlılıkları tartışılmıştır. Özellikle HT yönteminin doğruluğu, su altı manevralarının standardize edilmesi ve rezidual hacmin doğru belirlenmesi ile ilişkilidir. HYDP ise pratikliği ve daha az invaziv yapısıyla öne çıkmaktadır. Bununla birlikte, her iki yöntemde de birey özelliklerine bağlı hata payları mevcuttur. Sonuç olarak, bu yöntemlerin standardizasyonu ve çok bileşenli modellerle desteklenmesi, vücut kompozisyonu ölçümlerinde doğruluğu artırmaktadır.
