The quadriceps femoris muscle in 20-70-year-old subjects: relationship between knee extension torque, electrophysiological parameters, and muscle fiber characteristics.
Erik Stålberg,O. Borges,M. Ericsson,B. Essén‐Gustavsson,P. R. W. Fawcett,L. O. Nordesjö,B. Nordgren,R. Uhlin +7 more
TL;DR: It was concluded that this fall out of motor units also contributes to the reduction in torque, when compensatory reinnervation begins to fall, and other factors, such as reduction in muscle fiber contractility, metabolic factors, and central factors, may also play a role in age‐related reduction.

Effects of creatine loading and prolonged creatine supplementation on body composition, fuel selection, sprint and endurance performance in humans.
Luc J. C. van Loon,Audrey M. Oosterlaar,Fred Hartgens,Matthijs K. C. Hesselink,Rodney J. Snow,Anton J. M. Wagenmakers +5 more
TL;DR: There is definite evidence that prolonged creatine supplementation in humans does not increase muscle or whole-body oxidative capacity and, as such, does not influence substrate utilization or performance during endurance cycling exercise.

Effect of Pulmonary Rehabilitation on Peripheral Muscle Fiber Remodeling in Patients With COPD in GOLD Stages II to IV
Ioannis Vogiatzis,Gerasimos Terzis,Grigoris Stratakos,Evgenia Cherouveim,Dimitris Athanasopoulos,Stauroula Spetsioti,Ioannis Nasis,Panagiota Manta,Charis Roussos,Spyros Zakynthinos +9 more
TL;DR: Functional capacity and morphologic and typologic adaptations to rehabilitation in peripheral muscle fibers were similar across GOLD stages II to IV, and Pulmonary rehabilitation should be implemented in patients at all COPD stages.

Energy Metabolism during Repeated Sets of Leg Press Exercise Leading to Failure or Not
Esteban M. Gorostiaga,Ion Navarro-Amézqueta,Jose A. L. Calbet,Ylva Hellsten,Roser Cussó,Mario Guerrero,Cristina Granados,Miriam González-Izal,Javier Ibáñez,Mikel Izquierdo +9 more
TL;DR: In this paper, the influence of the number of repetitions per set on power output and muscle metabolism during leg press exercise was examined, and significant correlations (P<0.01) were observed between changes in muscle PCr and muscle lactate (R(2) = 0.46).

Effect of 8 Weeks of Overfeeding on Ectopic Fat Deposition and Insulin Sensitivity: Testing the “Adipose Tissue Expandability” Hypothesis
Darcy L. Johannsen,Yourka D. Tchoukalova,Charmaine S. Tam,Charmaine S. Tam,Jeffrey D. Covington,Wenting Xie,Jean-Marc Schwarz,Sudip Bajpeyi,Sudip Bajpeyi,Eric Ravussin +9 more
TL;DR: In experimental substantial weight gain, the presence of larger adipocytes did not promote ectopic lipid accumulation and smaller fat cells were associated with a worsened metabolic response to overfeeding.

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.
