Architectural Adaptations Of Muscle To Training And Injury: A Narrative Review Outlining The Contributions By Fascicle Length, Pennation Angle And Muscle Thickness [Accepted Manuscript], Ryan G. Timmins, Anthony J. Shield, Morgan D. Williams, Christian Lorenzen, David Opar Jan 2016

Architectural Adaptations Of Muscle To Training And Injury: A Narrative Review Outlining The Contributions By Fascicle Length, Pennation Angle And Muscle Thickness [Accepted Manuscript], Ryan G. Timmins, Anthony J. Shield, Morgan D. Williams, Christian Lorenzen, David Opar

Faculty of Health Sciences Publications

Background: The architectural characteristics of muscle (fascicle length, pennation angle muscle thickness) respond to varying forms of stimuli ( eg, training, immobilisation and injury ). Architectural changes following injury are thought to occur in response to the restricted range of motion experienced during rehabilitation and the associated neuromuscular inhibition. However, it is unknown if these differences exist prior to injury, and had a role in injury occuring ( prospectively ), or if they occur in response to the incident itself ( retrospectively ). Considering that the structure of a muscle will influence how it functions, it is of interest to understand how these architectural variations may ...

Satellite Cells In Human Skeletal Muscle Plasticity, Tim Snijders, Joshua P. Nederveen, Bryon R. Mckay, Sophie Joanisse, Lex B. Verdijk, Luc J. C. Van Loon, Gianni Parise

Faculty of Health Sciences Publications

Skeletal muscle satellite cells are considered to play a crucial role in muscle fiber maintenance, repair and remodeling. Our knowledge of the role of satellite cells in muscle fiber adaptation has traditionally relied on in vitro cell and in vivo animal models. Over the past decade, a genuine effort has been made to translate these results to humans under physiological conditions. Findings from in vivo human studies suggest that satellite cells play a key role in skeletal muscle fiber repair/remodeling in response to exercise. Mounting evidence indicates that aging has a profound impact on the regulation of satellite cells ...
