Low cell pH depresses peak power in rat skeletal muscle fibres at both 30 degrees C and 15 degrees C: implications for muscle fatigue

Autor: S T, Knuth, H, Dave, J R, Peters, R H, Fitts

Publikováno v: The Journal of physiology. 575(Pt 3)

Historically, an increase in intracellular H(+) (decrease in cell pH) was thought to contribute to muscle fatigue by direct inhibition of the cross-bridge leading to a reduction in velocity and force. More recently, due to the observation that the ef

Five myofibrillar lesion types in eccentrically challenged, unloaded rat adductor longus muscle--a test model

Autor: J L, Thompson, E M, Balog, R H, Fitts, D A, Riley

Publikováno v: The Anatomical record. 254(1)

Sarcomere disruptions are observed in the adductor longus (AL) muscles following voluntary reloading of spaceflown and hindlimb suspension unloaded (HSU) rat, which resemble lesions in eccentrically challenged muscle. We devised and tested an eccentr

Disproportionate loss of thin filaments in human soleus muscle after 17-day bed rest

Autor: D A, Riley, J L, Bain, J L, Thompson, R H, Fitts, J J, Widrick, S W, Trappe, T A, Trappe

Publikováno v: Musclenerve. 21(10)

Previously we reported that, after 17-day bed rest unloading of 8 humans, soleus slow fibers atrophied and exhibited increased velocity of shortening without fast myosin expression. The present ultrastructural study examined fibers from the same musc

Muscle fatigue: the cellular aspects

Autor: R H, Fitts

Publikováno v: The American journal of sports medicine. 24

High-intensity contractile activity causes a rapid fall in peak tension or force, a reduced shortening velocity, decline in power, prolonged twitch duration, a sarcolemma action potential with a prolonged duration, reduced amplitude, and a conduction

Muscle mechanics: adaptations with exercise-training

Autor: R H, Fitts, J J, Widrick

Publikováno v: Exercise and sport sciences reviews. 24

Based on the MHC isoform pattern, adult mammalian limb skeletal muscles contain two and, in some species, three types of fast fibers (Type IIa, IIx, and IIb), and one slow fiber (Type I). Slow muscles, such as the soleus, contain primarily the slow T
