Fat-Free Mass Is Positively Associated With Urine Specific Gravity in Athletes and Active Adults: A Quantitative Review.

ABSTRACT: Background: Urine specific gravity (USG) is a commonly used assessment method to estimate the prevalence of hypohydration, typically based on a common threshold of ≥ 1.020. Some research has shown that USG can vary based on body size and composition, but the evidence to date is limited. This review examined whether an association between fat-free mass (FFM), a component of body composition, and USG could be detected among published articles that have reported these variables in athletes and physically active individuals. Methods: By searching Google Scholar, the authors identified a large number of published articles (n = 161) reporting anthropometrics and USG. Only articles reporting data on adult samples of athletes or physically active individuals were included. Giv
