Journal ArticleDOI
Effect of two contrasting types of physical exercise on chronic neck muscle pain.
TL;DR: Specific strength training had high clinical relevance and led to marked prolonged relief in neck muscle pain and general fitness training showed only a small yet statistically significant acute pain reduction.
Journal ArticleDOI
Increase in muscle nociceptive substances and anaerobic metabolism in patients with trapezius myalgia: microdialysis in rest and during exercise
Lars Rosendal,Britt Larsson,Jesper Kristiansen,Michael Peolsson,Karen Søgaard,Michael Kjaer,Jan Sörensen,Björn Gerdle +7 more
TL;DR: Patients with chronic work-related trapezius myalgia have increased levels of muscle 5‐HT and glutamate that were correlated to pain intensity that indicate that peripheral nociceptive processes are active in work‐related TM.
Journal ArticleDOI
Molecular aging and rejuvenation of human muscle stem cells
Morgan E. Carlson,Charlotte Suetta,Michael J. Conboy,Per Aagaard,Abigail L. Mackey,Michael Kjaer,Irina M. Conboy +6 more
TL;DR: It is found that satellite cells are maintained in aged human skeletal muscle, but fail to activate in response to muscle attrition, due to diminished activation of Notch compounded by elevated transforming growth factor beta (TGF‐β)/phospho Smad3 (pSmad3).
Journal ArticleDOI
The effect of resistance training combined with timed ingestion of protein on muscle fiber size and muscle strength
Lars L. Andersen,Goran Tufekovic,Mette K Zebis,Regina M. Crameri,George Verlaan,Michael Kjaer,Charlotte Suetta,Peter Magnusson,Per Aagaard +8 more
TL;DR: A minor advantage of protein supplementation over carbohydrate supplementation during resistance training on mechanical muscle function was found, and the present results may have relevance for individuals who are particularly interested in gaining muscle size.
Journal ArticleDOI
Changes in muscle size and MHC composition in response to resistance exercise with heavy and light loading intensity
Lars Holm,Søren Reitelseder,Troels Gravers Pedersen,Simon Doessing,Susanne Germann Petersen,Allan Flyvbjerg,Jesper L. Andersen,Per Aagaard,Michael Kjaer +8 more
TL;DR: LL resistance training was sufficient to induce a small but significant muscle hypertrophy in healthy young men, however, LL resistanceTraining was inferior to HL training in evoking adaptive changes in muscle size and contractile strength and was insufficient to induce changes in MHC composition.
