Human skeletal muscle carnitine palmitoyltransferase I activity determined in isolated intact mitochondria.
TL;DR: It is suggested that CPT I activity can be accurately and reliably measured in intact mitochondria isolated from human muscle biopsy samples and higher activities in aerobically trained subjects appeared to be the result of increased mitochondrial content in both men and women.

Human mitochondrial haplogroup H: the highest VO2max consumer--is it a paradox?
Diana Martínez-Redondo,Ana Marcuello,José A. Casajús,Ignacio Ara,Yahya Dahmani,Julio Montoya,Eduardo Ruiz-Pesini,Manuel J. López-Pérez,Carmen Díez-Sánchez +8 more
TL;DR: The results strongly suggest that ROS production is responsible for the higher VO(2max) found in the H variant, which helps to explain some reported associations between mitochondrial haplogroups and mtOD with longevity, sperm motility, premature aging and susceptibility to different pathologies.

Long- but not short-term multifactorial intervention with focus on exercise training improves coronary endothelial dysfunction in diabetes mellitus type 2 and coronary artery disease.
Sebastian Sixt,Sebastian Beer,Matthias Blüher,Nicolai Korff,Thomas Peschel,Melanie Sonnabend,Daniel Teupser,Joachim Thiery,Volker Adams,Gerhard Schuler,Josef Niebauer,Josef Niebauer +11 more
TL;DR: This is the first study to demonstrate improvement in coronary endothelial function by a multifactorial intervention which focused on exercise training in patients with T2DM, and this coincided with improved markers of hyperglycaemia, insulin sensitivity, and inflammation both in serum and skeletal muscle biopsies.

The mechanistic bases of the power-time relationship: muscle metabolic responses and relationships to muscle fibre type.
Anni Vanhatalo,Matthew I. Black,Fred J. DiMenna,Jamie R. Blackwell,Jakob Friis Schmidt,Christopher Thompson,Lee J. Wylie,Magni Mohr,Magni Mohr,Jens Bangsbo,Peter Krustrup,Peter Krustrup,Andrew M. Jones +12 more
TL;DR: In this article, the authors reported a positive correlation between critical power and highly oxidative type I muscle fibres and showed that muscle metabolic steady-state is attainable CP by using a 3-min all-out cycling test.

Different response to eccentric and concentric training in older men and women.
Matthias Mueller,Fabio Andreas Breil,Michael Vogt,Roger Steiner,Kurt Lippuner,Albrecht Popp,Stephan Klossner,Hans Hoppeler,Christoph Däpp +8 more
TL;DR: It was concluded that both RET and EET are beneficial for the elderly with regard to muscle functional and structural improvements but differ in their spectrum of effects.

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.
Journal ArticleDOI
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.
