Leucine-supplemented meal feeding for ten days beneficially affects postprandial muscle protein synthesis in old rats.
Acute leucine supplementation of the diet has been shown to blunt defects in postprandial muscle protein metabolism in old rats. This study was undertaken to determine whether the effect of leucine persists in a 10-d experiment. For this purpose, adult (9 mo) and old (21 mo) rats were fed a semiliquid 18.2 g/100 g protein standard diet during the 8-h dark period for 1 mo. Then, each group was g...
متن کاملLower recovery of muscle protein lost during starvation in old rats despite a stimulation of protein synthesis.
Sarcopenia could result from the inability of an older individual to recover muscle lost during catabolic periods. To test this hypothesis, we compared the capacity of 5-day-refed 12- and 24-mo-old rats to recover muscle mass lost after 10 days without food. We measured gastrocnemius and liver protein synthesis with the flooding-dose method and also measured nitrogen balance, 3-methylhistidine ...
متن کاملMuscle Protein Synthesis – Effects of Metabolic Stress and Feeding
Surgical trauma and critical illness are pathophysiological conditions where the metabolic stress leads to an imbalance between protein synthesis and protein breakdown, resulting in a net loss of body proteins. A major part of the protein losses comes from skeletal muscle. Muscle depletion is associated with a high morbidity and mortality. To understand the changes that occur during critical il...
متن کاملLeucine pulses enhance skeletal muscle protein synthesis during continuous feeding in neonatal pigs.
Infants unable to maintain oral feeding can be nourished by orogastric tube. We have shown that orogastric continuous feeding restricts muscle protein synthesis compared with intermittent bolus feeding in neonatal pigs. To determine whether leucine infusion can be used to enhance protein synthesis during continuous feeding, neonatal piglets received the same amount of formula enterally by oroga...
متن کاملProtein feeding pattern, casein feeding, or milk-soluble protein feeding did not change the evolution of body composition during a short-term weight loss program.
Studies have shown that timing of protein intake, leucine content, and speed of digestion significantly affect postprandial protein utilization. Our aim was to determine if one can spare lean body mass during energy restriction by varying the quality and the timing of protein intake. Obese volunteers followed a 6-wk restricted energy diet. Four groups were compared: casein pulse, casein spread,...
