Testosterone administration to elderly men increases skeletal muscle strength and protein synthesis.
Aging men develop a significant loss of muscle strength that occurs in conjunction with a decline in serum testosterone concentrations. We investigated the effects of testosterone administration to six healthy men [67 +/- 2 (SE) yr] on skeletal muscle protein synthesis, strength, and the intramuscular insulin-like growth factor I (IGF-I) system. Elderly men with serum testosterone concentration...

متن کاملEffect of testosterone on muscle mass and muscle protein synthesis.
We have studied the effect of a pharmacological dose of testosterone enanthate (3 mg.kg-1.wk-1 for 12 wk) on muscle mass and total-body potassium and on whole-body and muscle protein synthesis in normal male subjects. Muscle mass estimated by creatinine excretion increased in all nine subjects (20% mean increase, P less than 0.02); total body potassium mass estimated by 40K counting increased i...
متن کاملProtein synthesis in tissues of growing lambs.
1. The fractional rate of protein synthesis (FSR) in tissues of nine growing lambs (4-5 months of age) was estimated following continuous infusion of L-[4,5-3H]leucine for a period of 7 h. Minimum and upper estimates of FSR were obtained assuming that the specific radioactivity (SRA) of leucine in blood plasma and tissue homogenate respectively defined that of leucyl tRNA. 2. Mean upper estimat...
متن کاملHindlimb protein turnover and muscle protein synthesis in lambs: a comparison of techniques.
A combination of arterio-venous difference, kinetic isotope transfer and blood flow rate techniques were used to measure tyrosine metabolism across hindlimb tissues of nine growing lambs (average live weight 36.5 kg) fed on a range of dry matter intakes. Muscle protein synthesis was measured using a continuous infusion technique and compared with simultaneous estimates of hindlimb protein turno...
