Corticosteroids Reduce the Tensile Strength of Isolated Collagen Fascicles
Bjarki Haraldsson,Henning Langberg,Per Aagaard,Per Aagaard,Anne-Marie Zuurmond,Benno van El,Jeroen DeGroot,Michael Kjaer,S. Peter Magnusson +8 more
TL;DR: Data show that the tensile strength of isolated fascicles is markedly reduced after 3-and 7-day incubation in both high and low concentration of corticosteroids, although the observed effect on whole tendon remains unknown.
Journal ArticleDOI
Release of tensile strain on engineered human tendon tissue disturbs cell adhesions, changes matrix architecture, and induces an inflammatory phenotype.
Monika L. Bayer,Peter Schjerling,Andreas Herchenhan,Cédric Zeltz,Katja M. Heinemeier,Lise Christensen,Michael Krogsgaard,Donald Gullberg,Michael Kjaer +8 more
TL;DR: Findings indicate an important role of mechanical loading for cellular and matrix responses in tendon, including that loss of tension leads to a decrease in phenotypical markers for tendon, while expression of pro-inflammatory mediators is induced.
Journal ArticleDOI
Increased proportion of megafibers in chronically painful muscles
TL;DR: It is shown that trapezius myalgia is associated with a significantly higher percentage of grossly hypertrophied type I muscle fibers with poor capillarization – type I megafibers.
Journal ArticleDOI
Effect of physical training on the capacity to secrete epinephrine
Michael Kjaer,H. Galbo +1 more
TL;DR: The results indicate that training increases the capacity to secrete epinephrine.
Journal ArticleDOI
Old women with a recent fall history show improved muscle strength and function sustained for six months after finishing training
Nina Beyer,Lene Simonsen,Jens Bülow,Tove Lorenzen,D V Jensen,Lone Larsen,Ulla Husballe Rasmussen,Michael J. Rennie,Michael Kjaer +8 more
TL;DR: A 6-month multidimensional training program produced significant improvements in physiological and functional risk factors for falls and disability in women aged 70–90 years with a recent history of falls.
