Measurement of total body water using H dilution: impact of different calculations for determining body fat

This study estimated total body water (TBW) in four groups (twelve per group; sedentary and highly trained men and women) at the time of H dosing (T0) and after a 3·5 h equilibration period (Teq). Standard TBW calculations were employed at T0 (no correction for disproportionate urinary tracer loss) and Teq (correction for urinary tracer loss only), plus those calculations that corrected for a d...

Measurement of total body water using 2H dilution: impact of different calculations for determining body fat.

This study estimated total body water (TBW) in four groups (twelve per group; sedentary and highly trained men and women) at the time of 2H dosing (T0) and after a 3.5 h equilibration period (Teq). Standard TBW calculations were employed at T0 (no correction for disproportionate urinary tracer loss) and Teq (correction for urinary tracer loss only), plus those calculations that corrected for a ...

Measurement of Total Body Exchangeable Potassium

Studies were undertaken to appraise the cellular potassium status of children with the nephrotic syndrome, utilizing two techniques: Measurement of total body exchangeable potassium (Ke) by isotope dilution and determination of the potassium content of red blood cells by direct chemical analysis. The Ke values obtained on the nephrotic children are compared to similar data obtained on "hospital...

Estimating Body Composition of Lizards from Total Body Electrical Conductivity and Total Body Water

Nondestructive methods of estimating body composition are crucial for measuring energy budgets of free-ranging animals. However, most methods have proved to be either difficult or inaccurate for estimating lipid mass, particularly in small animals. I validated the use of total body electrical conductivity (TOBEC) and total body water (TBW) to estimate lean mass and nonpolar lipid mass in the li...
