Physics of muscle contraction [PDF]
Reports on Progress in Physics, 2018 In this paper we report, clarify and broaden various recent efforts to complement the chemistry-centered models of force generation in muscles by mechanics-centered models. The physical mechanisms of interest can be grouped into two classes: passive and active.

Cold Spring Harbor Perspectives in Biology, 2018 Muscle cells are designed to generate force and movement. There are three types of mammalian muscles-skeletal, cardiac, and smooth. Skeletal muscles are attached to bones and move them relative to each other. Cardiac muscle comprises the heart, which pumps blood through the vasculature.

Signaling in Muscle Contraction [PDF]
Cold Spring Harbor Perspectives in Biology, 2015 Signaling pathways regulate contraction of striated (skeletal and cardiac) and smooth muscle. Although these are similar, there are striking differences in the pathways that can be attributed to the distinct functional roles of the different muscle types.

Glycolysis Mediated Sarcoplasmic Reticulum Ca Signal Regulates Mitochondria Ca during Skeletal Muscle Contraction [PDF]
운동과학, 2017 PURPOSE This study was to investigate the Glycolysis mediated sarcoplasmic reticulum (SR) Ca2+ signal regulates mitochondria Ca2+ during skeletal muscle contraction by using glycolysis inhibitor.

Intracellular oxygen tension limits muscle contraction-induced change in muscle oxygen consumption under hypoxic conditions during Hb-free perfusion. [PDF]
, 2017 Under acute hypoxic conditions, the muscle oxygen uptake (mV˙O2) during exercise is reduced by the restriction in oxygen-supplied volume to the mitochondria within the peripheral tissue. This suggests the existence of a factor restricting the mV˙O2 under

Biology, 2014 Myosin filaments in vertebrate striated muscle have a long roughly cylindrical backbone with cross-bridge projections on the surfaces of both halves except for a short central bare zone. In the middle of this central region the filaments are cross-linked

Activation analysis of the lower limb muscles of cyclists during pedaling
Nihon Kikai Gakkai ronbunshu, 2020 It is important to elucidate the lower limb motion based on the activation of lower limb muscles during pedaling to improve pedaling performance of cyclists.

Chemical changes in the adductor muscle of the cheliped of the crayfish in relation to the double motor innervation [PDF]
, 1938 Work from this laboratory has shown that a number of the striated muscles of the legs of the crayfish show a typical motor innervation (1). Such muscles are innervated by two motor fibers only, each causing a different type of contraction.

Biology, 2019 Unlike electron microscopy, which can achieve very high resolution but to date can only be used to study static structures, time-resolved X-ray diffraction from contracting muscles can, in principle, be used to follow the molecular movements involved in ...

Physiological Reports, 2020 Aim Muscle contraction stimulates skeletal muscle glucose transport. Since it occurs independently of insulin, it is an important alternative pathway to increase glucose transport in insulin‐resistant states, but the intracellular signaling mechanisms ...
