that on average 16% of protein is nitrogen). A major Assessment of status and nitrogen balance problem associated with this is that most patients are not in balance at any one time. To overcome this one The nutritional assessment of patients with chronic needs to undertake nitrogen balance whereby patients renal failure includes an assessment of body fat, fat are admitted to a metabolic ward an...

This study aimed to estimate nitrogen balance and protein requirements in adolescent sprint athletes as a function of growth rate and physical development. Sixty adolescent sprint athletes were followed up biannually over a 2-yr period. Individual growth curves and age at peak height velocity were determined. Skeletal muscle mass (SMM) was estimated based on anthropometric measurements and fat ...

BACKGROUND The associations between nitrogen metabolism and bone turnover during bed rest are still not completely understood. METHODS We measured nitrogen balance (nitrogen intake minus urinary nitrogen excretion) and biochemical metabolic markers of calcium and bone turnover in six males before head-down tilt bed rest (baseline), during 2, 10, and 14 weeks of immobilization, and after reamb...

To compare their effects on nitrogen balance, diets containing either lactalbumin whole protein, its peptide-rich enzymic hydrolysate or an equivalent mixture of free amino acids as the sole source of dietary nitrogen were fed to two healthy subjects, each studied for 38 days on two separate occasions. The nitrogen intake (47 mg/kg body wt/day) induced a state of negative nitrogen balance, stim...
