Two weeks of early time restricted feeding (eTRF) improves skeletal muscle insulin and anabolic sensitivity in healthy men
Robert G. Jones,Pardeep Pabla,Joanne Mallinson,Aline Nixon,Tariq Taylor,Andrew J. Bennett,Kostas Tsintzas +6 more
TL;DR: Under free-living conditions, eTRF improves whole-body insulin sensitivity and increases skeletal muscle glucose and BCAA uptake and represents chronic adaptations rather than the effect of the last bout of overnight fast.

Uncoupled skeletal muscle mitochondria contribute to hypermetabolism in severely burned adults
Craig Porter,David N. Herndon,Elisabet Børsheim,Tony Chao,Paul T. Reidy,Michael S. Borack,Blake B. Rasmussen,Maria Chondronikola,Manish Kumar Saraf,Labros S. Sidossis +9 more
TL;DR: It is hypothesized that uncoupling of oxidative phosphorylation in skeletal muscle mitochondria contributes to increased metabolic rate in burn survivors, and skeletal muscle mitochondrial function in healthy and severely burned adults is determined.

Lipid droplet remodelling and reduced muscle ceramides following sprint interval and moderate-intensity continuous exercise training in obese males
Sam O. Shepherd,Matthew Cocks,Peter J. Meikle,Natalie A. Mellett,Aaron M. Ranasinghe,Thomas A. Barker,Anton J. M. Wagenmakers,Christopher S. Shaw +7 more
TL;DR: The hypothesis that short-term sprint interval training and moderate-intensity continuous training in obese individuals would increase perilipin (PLIN) expression, increase the proportion of LDs in contact with mitochondria and reduce muscle concentrations of DAGs and ceramides is confirmed.
Journal ArticleDOI
Carbohydrate metabolism during prolonged exercise and recovery: interactions between pyruvate dehydrogenase, fatty acids, and amino acids.
TL;DR: Studying the time course of changes in substrate utilization in six men who cycled at 44+/-1% peak oxygen consumption until exhaustion found reduced pyruvate production was primarily associated with reduced carbohydrate oxidation, whereas the greatest production of pyruVate was related to glutamate, glutamine, and alanine metabolism in early exercise.

Skeletal Muscle Mitochondrial Protein Synthesis and Respiration Increase With Low-Load Blood Flow Restricted as Well as High-Load Resistance Training
Thomas Groennebaek,Nichlas Riise Jespersen,J. E. Jakobsgaard,Peter Sieljacks,Jakob Wang,Emil Rindom,Robert V. Musci,Hans Erik Bøtker,Karyn L. Hamilton,Benjamin F. Miller,Frank Vincenzo de Paoli,Kristian Vissing +11 more
TL;DR: Intriquingly, BFRRE produces similar mitochondrial adaptations at a markedly lower load, which entail great clinical perspective for populations in whom exercise with high loading is untenable.

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.

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

Muscle Glycogen Synthesis after Exercise : an Enhancing Factor localized to the Muscle Cells in Man
Jonas Bergström,Eric Hultman +1 more
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.
