Abstract
Underwater weighing with full lung expiration has been established as a valid method to assess body composition. Many people do not prefer this method due to various reasons. Hydrostatic weighing with head above water at full lung capacity has been tested although not accepted as an alternative method. Purpose: The main purpose of this study is to examine if hydrostatic weighing with the head above water could be a better method to measure body composition. Methods: Fifty-nine subjects (F=29, M=30) participated in performing four different methods of underwater weighing: complete immersion at full lung expiration (UWWRV) and total lung capacity (UWWTLC), and partial immersion at full lung expiration (HAWRV) and total lung capacity (HAWTLC). Bland-Altman Plots and ANOVA were used to test bias across the range of means. Results: There was a significant difference between HAWRV and UWWRV for both males (t = 26.799, df = 29, p < 0.001) and females (t = 40.535, df = 28, p < 0.001). There was a significant difference between HAWTLC versus HAWRV in males (t = -24.436, df= 29, p
