Journal ArticleDOI
Differential glucose uptake in quadriceps and other leg muscles during one-legged dynamic submaximal knee-extension exercise.
Kari K. Kalliokoski,Robert Boushel,Henning Langberg,Celena Scheede-Bergdahl,Ann Kathrine Ryberg,Simon Døssing,Andreas Kjaer,Michael Kjaer +7 more
TL;DR: It is suggested that posterior thigh muscles and lower leg muscles are more active than hitherto thought even during this moderate exercise intensity, and suggests that muscle activity is not equal between quadriceps muscles in this exercise model.
Journal ArticleDOI
In vitro tendon tissue development from human fibroblasts demonstrates collagen fibril diameter growth associated with a rise in mechanical strength
TL;DR: The present study demonstrates that 3D tendon constructs can be formed by isolated human tendon fibroblasts, and when these constructs are subjected to static self‐generated tension, the fibrils will grow in size and strength approaching that of adult human tendon in vivo.
Journal ArticleDOI
Influence of Oral Contraceptive Use on Adaptations to Resistance Training.
Line Barner Dalgaard,Ulrik Dalgas,Jesper L. Andersen,Nicklas B. Rossen,Andreas Buch Møller,Hans Stødkilde-Jørgensen,Jens Otto Lunde Jørgensen,Vuokko Kovanen,Christian Couppé,Henning Langberg,Michael Kjaer,Mette Hansen,Mette Hansen +12 more
TL;DR: Use of OCs during a 10-week supervised progressive resistance training program was associated with a trend toward a greater increase in muscle mass and a significantly greater increased in type I muscle fiber area compared to controls, yet, use of OC's did not influence the overall increase in Muscle strength related to training.
Journal ArticleDOI
Integrated method for quantitative morphometry and oxygen transport modeling in striated muscle.
Abdullah A. Al-Shammari,Abdullah A. Al-Shammari,Roger W. P. Kissane,Simon Holbek,Abigail L. Mackey,Abigail L. Mackey,Thomas Rostgaard Andersen,Eamonn A. Gaffney,Michael Kjaer,Michael Kjaer,Stuart Egginton +10 more
TL;DR: An integrated package that identifies optimal protocols for identification of important input elements, processing of digitized images with semiautomated routines, and incorporation of these data into a mathematical modeling framework with computed output visualized as the tissue partial pressure of O2 (Po2) distribution across a biopsy sample is presented.
Journal ArticleDOI
GH/IGF‐I axis and matrix adaptation of the musculotendinous tissue to exercise in humans
Katja M. Heinemeier,Katja M. Heinemeier,Abigail L. Mackey,Abigail L. Mackey,Simon Doessing,Simon Doessing,Mette Hansen,Mette Hansen,Monika L. Bayer,Monika L. Bayer,Rie Harboe Nielsen,Rie Harboe Nielsen,Andreas Herchenhan,Andreas Herchenhan,Nikolaj M Malmgaard-Clausen,Nikolaj M Malmgaard-Clausen,Michael Kjaer,Michael Kjaer +17 more
TL;DR: Observations support a stimulatory effect of GH/IGF‐I on the connective tissue in muscle and tendon, which appears far more potent than the effect on contractile proteins of skeletal muscle.
