Long-Term Skeletal Muscle Mitochondrial Dysfunction is Associated with Hypermetabolism in Severely Burned Children
Craig Porter,David N. Herndon,Elisabet Børsheim,Nisha Bhattarai,Tony Chao,Tony Chao,Paul T. Reidy,Blake B. Rasmussen,Clark R. Andersen,Oscar E. Suman,Oscar E. Suman,Labros S. Sidossis +11 more
TL;DR: Respiratory capacity and function of skeletal muscle mitochondria in healthy individuals and in burn victims for up to 2 years postinjury are determined and quantitative and qualitative derangements in skeletal muscle bioenergetics likely contribute to the long-term pathophysiological stress response to burn trauma.

Effect of endurance training on muscle TCA cycle metabolism during exercise in humans
TL;DR: It is concluded that, after aerobic training, cycle endurance capacity is not limited by a decrease in muscle [TCAI], which is consistent with reduced carbon flux through alanine aminotransferase.
Journal ArticleDOI
Energy cost and metabolic regulation during intermittent and continuous tetanic contractions in human skeletal muscle
TL;DR: It is suggested that the increased ATP utilization of intermittent contractions is associated with enhanced Ca2+-transport ATPase activity during relaxation and enhanced actomyosin ATP enzyme activity during the early portion of each contraction.

TL;DR: Cold‐water immersion during recovery from resistance‐type exercise lowers the capacity of the muscle to take up and/or direct dietary protein‐derived amino acids towards de novo myofibrillar protein accretion.

Similar changes of gene expression in human skeletal muscle after resistance exercise and multiple fine needle biopsies
Birgit Friedmann-Bette,Fides Regina Schwartz,Holger Eckhardt,Rudolf Billeter,Gabriel A. Bonaterra,Ralf Kinscherf +5 more
TL;DR: It is concluded that multiple fine needle biopsies obtained from the same muscle region can per se influence the expression of marker genes induced by an acute bout of resistance exercise.

Diet, Muscle Glycogen and Physical Performance
TL;DR: It has been shown that the glycogen content and, consequently, the long-term work capacity can be appreciably varied by instituting different diets after glycogen depletion.

Glycogen, glycolytic intermediates and high-energy phosphates determined in biopsy samples of musculus quadriceps femoris of man at rest. Methods and variance of values.
TL;DR: Variation in muscle content of ATP, ATP + ADP + AMP, phosphorylcreatine (PC), creatine (Cr), PC + Cr, and glycogen, between legs, between sites on the same muscle, or as a result of error introduced during analysis, was small compared with the between-individuals variance.

TL;DR: Glycogen depletion pattern in human skeletal muscle fibres was studied after bicycle exercise of varying intensity performed at different pedalling rates.

TL;DR: Goldstein1 has shown that a humoral factor, which decreases the blood glucose concentration, is released during exercise and it is known that the insulin requirement decreases in diabetic subjects during exercise.
