Tendon collagen synthesis declines with immobilization in elderly humans: no effect of anti-inflammatory medication
Kasper Dideriksen,Anders Ploug Boesen,Søren Reitelseder,Christian Couppé,Christian Couppé,Rene B. Svensson,Peter Schjerling,S. Peter Magnusson,S. Peter Magnusson,Lars Holm,Michael Kjaer +10 more
TL;DR: In elderly human tendons, collagen protein synthesis decreased after 2 wk of immobilization, whereas tendon stiffness and modulus were only marginally reduced, and NSAIDs had no influence upon this, which indicates an importance of mechanical loading for maintenance of tendon collagen turnover.
Journal ArticleDOI
Skeletal muscle adaptation to immobilization and subsequent retraining in elderly men: No effect of anti-inflammatory medication.
Kasper Dideriksen,Anders Ploug Boesen,Jesper Kristiansen,Stig Peter Magnusson,Peter Schjerling,Lars Holm,Michael Kjaer +6 more
TL;DR: Two weeks of lower limb immobilization lead to a reduction in muscle mass and strength, but these parameters were restored already after2 weeks of retraining and whey protein supplementation, and NSAID treatment did not significantly influence this in elderly.
Journal ArticleDOI
Load magnitude affects patellar tendon mechanical properties but not collagen or collagen cross-linking after long-term strength training in older adults
Christian Skou Eriksen,Christian Skou Eriksen,Rene B. Svensson,Anne Theil Gylling,Anne Theil Gylling,Christian Couppé,S. Peter Magnusson,Michael Kjaer,Michael Kjaer +8 more
TL;DR: Despite equal improvements in tendon size after moderate and heavy load resistance training, only heavy load training seemed to maintain tendon mechanical properties in old age.

Improved Functional Performance in Geriatric Patients During Hospital Stay.
Anders Karlsen,Mads Rohde Loeb,Kristine Bramsen Andersen,Katrine Jeong Joergensen,Frederik Ulrik Scheel,Ida Fanny Turtumoeygard,Alberto Luis Rodrigues Perez,Michael Kjaer,Nina Beyer +8 more
TL;DR: Functional performance of the lower extremities in geriatric patients improves moderately over the time of a hospital stay of less than 14 days, with larger improvements in patients with high activity level.
