Total-body skeletal muscle mass:estimation by a new dual-energy X-ray absorptiometry method
Body composition nutritional assessment skeletal muscle mass magnetic resonance imaging dual-energy X-ray absorptiometry
2016/12/19
Background: Skeletal muscle (SM) is an important body-composition component that remains difficult and impractical to quantify by most investigators outside of specialized research centers. A lar...
Effect of hypoenergetic feeding and refeeding on muscle and mononuclear cell activities of mitochondrial complexes I–IV in enterally fed rats
mitochondrial complexes I–IV electron transport chain rats
2016/6/13
Previous studies suggested that cell energetics are
altered by malnutrition.
Functional and metabolic early changes in calf muscle occurring during nutritional repletion in malnourished elderly patients
inorganic phosphate glycogen isokinetic peak torque
2016/6/13
Metabolic alterations in skeletal muscle associated
with malnutrition and the potential reversibility of such
alterations during refeeding are not fully understood.
Effects of an omnivorous diet compared with a lactoovovegetarian diet on resistance-training-induced changes in body composition and skeletal muscle in older men
Elderly men lactoovovegetarian diet muscle creatine
2016/6/2
Very limited data suggest that meat consumption
by older people may promote skeletal muscle hypertrophy in
response to resistance training (RT).
Determination of glutamine in muscle protein facilitates accurate assessment of proteolysis and de novo synthesis–derived endogenous glutamine production
Glutamine glutamic acid muscles
2016/6/1
Results of tracer studies indicate that skeletal muscle
contributes to <70% of overall glutamine production in
healthy adults; the contribution of de novo synthesis being estimated
at <60%. However...
Determination of skeletal muscle and fat-free mass by nuclear and dual-energy X-ray absorptiometry methods in men and women aged 51–84 y
bioimpedance analysis aging anthropometry
2016/6/1
Skeletal muscle mass (SMM) and fat-free mass
(FFM) are important variables in nutritional studies. Accurate
techniques for measuring these variables have not been thoroughly
validated in elderly su...
Physical activity, protein intake, and appendicular skeletal muscle mass in older men
Aging sarcopenia uniaxial accelerometer
2016/5/31
Aging is associated with physical inactivity, low
energy intake, and loss of skeletal muscle mass. It is not clear
whether regular physical activity and adequate dietary protein
intake can attenuat...
Impact of Muscle Glycogen Availability on the Capacity for Repeated Exercise in Man
NUTRITION METABOLISM PERFORMANCE SUCROSE
2017/4/13
Purpose: This study aims to examine whether muscle glycogen availability is associated with fatigue in a repeated exercise bout following short-term recovery.
Methods: Ten endurance-trained individua...
Influence of nutrient intake on antioxidant capacity, muscle damage and white blood cell count in female soccer players
Immune response Inflammation Antioxidant enzymes
2015/7/23
Soccer is a form of exercise that induces inflammatory response, as well as an increase in free radicals
potentially leading to muscle injury. Balanced nutritional intake provides important antioxida...
Consumption of fluid skim milk promotes greater muscle protein accretion after resistance exercise than does consumption of an isonitrogenous and isoenergetic soy-protein beverage1,2,3
Skeletal muscle protein synthesis dietary protein feeding hypertrophy
2008/12/12
Background:Resistance exercise leads to net muscle protein accretion through a synergistic interaction of exercise and feeding. Proteins from different sources may differ in their ability to support m...
Body composition, muscle function, and energy expenditure in patients with liver cirrhosis: a comprehensive study
Liver disease nutritional status protein depletion energy expenditure body composition neutron activatio
2008/12/12
Background: Data describing the nutritional status of patients with liver cirrhosis of diverse origin, as assessed by direct body-composition methods, are limited.Objective: We sought to provide a com...
Inadequate protein intake affects skeletal muscle transcript profiles in older humans 1,2,3
Dietary protein aging skeletal muscle transcript profile microarray gene expression
2008/12/11
Background: Inadequate dietary protein intake causes adverse changes in the morphology and function of skeletal muscle. These changes may be reflected in early alterations in muscle messenger RNA leve...
Skeletal muscle lipid deposition and insulin resistance: effect of dietary fatty acids and exercise1,2,3
Insulin resistance skeletal muscle intramyocellular triacylglycerol dietary fat exercise
2008/12/10
Mounting evidence indicates that elevated intramyocellular triacylglycerol concentrations are associated with diminished insulin sensitivity in skeletal muscle. This lipid accumulation is most likely ...
