Protein-containing nutrient supplementation following strength training enhances the effect on muscle mass, strength, and bone formation in postmenopausal women.
Lars Holm,Jens Lykkegaard Olesen,Keitaro Matsumoto,Tatsuya Doi,Masao Mizuno,Thomas J. Alsted,Abigail L. Mackey,Peter Schwarz,Michael Kjaer +8 more
TL;DR: It is reported that nutrient supplementation results in superior improvements in muscle mass, muscle strength, femoral neck BMD, and bone formation during 24 wk of strength training, emphasizing the significance of postexercise nutrient supply on musculoskeletal maintenance.

Effects of dichloroacetate infusion on human skeletal muscle metabolism at the onset of exercise
Richard A. Howlett,George J. F. Heigenhauser,Eric Hultman,Melanie G. Hollidge-Horvat,Lawrence L. Spriet +4 more
TL;DR: The hypothesis that increased provision of substrate by DCA infusion increases oxidative metabolism during the rest-to-work transition is supported, resulting in decreased PCr utilization and an improved cellular energy state at the onset of exercise.

Human skeletal muscle malonyl-CoA at rest and during prolonged submaximal exercise.
TL;DR: Human skeletal muscle malonyl-CoA content is less than reported in rat skeletal muscle at rest, does not decrease with prolonged submaximal exercise, and is not predictive of increased fatty acid oxidation during exercise.

Differential Utilization of Saturated Palmitate and Unsaturated Oleate: Evidence From Cultured Myotubes
TL;DR: The results indicate that oleic acid is preferable as fatty acid as it accumulates to a lesser extent as DAG and TAG than palmitic acid.

Fibre-Specific Responses to Endurance and Low Volume High Intensity Interval Training: Striking Similarities in Acute and Chronic Adaptation

TL;DR: Results suggest that 30 minutes of END exercise at ∼65%VO2peak or 4 minutes of LV-HIT at ∼170% VO2peak induce comparable changes in the intra-myocellular environment (glycogen content and signaling activation); correspondingly, training-induced adaptations resulting for these protocols, and other HIT and END protocols are strikingly similar.

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

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.
