Single muscle fiber contractile properties of young competitive distance runners.
The purpose of this investigation was to characterize the contractile properties of individual slow- and fast-twitch myofibers from highly trained distance runners. Muscle biopsies were obtained from the gastrocnemius of eight competitive runners (Run) and eight recreationally active individuals (Rec). Slow-twitch [myosin heavy chain (MHC) I] and fast-twitch (MHC IIa) myofibers were isolated an...
متن کاملRelationship between knee walking kinematics and muscle flexibility in runners.
CONTEXT Decreased flexibility in muscles and joints of lower extremities is commonly observed in runners. Understanding the effect of decreased flexibility on knee walking kinematics in runners is important because, over time, altered gait patterns can make runners vulnerable to overuse injuries or degenerative pathologies. OBJECTIVES To compare hamstring and iliotibial-band (ITB) flexibility...
متن کاملRelationship between muscle fiber types and sizes and muscle architectural properties in the mouse hindlimb.
Skeletal muscle fiber and architectural properties both contribute to the functional behavior of a muscle. This study uses discriminant analysis and mathematical modeling to identify the structurally and functionally significant properties. The architectural properties of fiber length, muscle length, and pennation angle are found to be the most structurally significant parameters, whereas fiber...
متن کاملThe relationship between human skeletal muscle pyruvate dehydrogenase phosphatase activity and muscle aerobic capacity.
Pyruvate dehydrogenase (PDH) is a mitochondrial enzyme responsible for regulating the conversion of pyruvate to acetyl-CoA for use in the tricarboxylic acid cycle. PDH is regulated through phosphorylation and inactivation by PDH kinase (PDK) and dephosphorylation and activation by PDH phosphatase (PDP). The effect of endurance training on PDK in humans has been investigated; however, to date no...
متن کاملHeat stroke in long distance runners.
Four cases of young cadets who developed severe heat stroke while on a cross country run in Doon Valley are reported. Physical exertion alone caused the episode in a homeothermic environment. One patient continued to have left facial nerve palsy.
