Increasing whole-body energetic stress does not augment fasting-induced changes in human skeletal muscle.

TL;DR: In this article, the authors tested the hypotheses that fasting-induced changes in human muscle occur shortly after food withdrawal and are modulated by whole-body energetic stress, and found that human skeletal muscle signaling, mRNA/protein expression, and substrate storage appear to be unaffected by whole body energetic stress during the initial hours of fasting.

Differences in Mitochondrial Coupling Reveal a Novel Signature of Mitohormesis in Muscle of Healthy Individuals
Lauren M. Sparks,Leanne M. Redman,Kevin E. Conley,Mary-Ellen Harper,Andrew Hodges,Alexey Eroshkin,Sheila R. Costford,Meghan E. Gabriel,Fanchao Yi,Cherie Shook,Heather H. Cornnell,Eric Ravussin,Steven R. Smith,Steven R. Smith +13 more
TL;DR: Higher muscle mitochondrial coupling is accompanied by an overall elevation in mitochondrial function, a novel transcriptional signature of oxidative stress and mitochondrial remodeling and indications of an mitochondrial unfolded protein response.

The role of the perilipin proteins in regulating intramuscular lipid metabolism: effect of exercise training
TL;DR: Novel data is generated that contributes to the understanding of the underlying mechanisms that govern the relationship between IMTG metabolism and insulin sensitivity as well as a new constant-workload SIT protocol with regards to improving insulin sensitivity in obese individuals.

TL;DR: In this article, the effects of exercise, training status, and sex on 24-hour free-living dietary phenylalanine incorporation into skeletal muscle proteins were determined in controlled laboratory studies in males.

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: 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.
