The Intriguing Dual Lattices of the Myosin Filaments in Vertebrate Striated Muscles: Evolution and Advantage

open access: yesBiology, 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

open access: yesNihon 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.

The Interacting Head Motif Structure Does Not Explain the X-Ray Diffraction Patterns in Relaxed Vertebrate (Bony Fish) Skeletal Muscle and Insect (Lethocerus) Flight Muscle

open access: yesBiology, 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 ...

The p21‐activated kinase 2 (PAK2), but not PAK1, regulates contraction‐stimulated skeletal muscle glucose transport

open access: yesPhysiological 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 ...

Voluntary Muscle Contraction Detection Algorithm Based on LSTM for Muscle Quality Measurement Algorithm

open access: yesApplied Sciences, 2021
In this paper, we propose the long–short-term memory (LSTM)-based voluntary and non-voluntary (VNV) muscle contraction classification algorithm in an electrical stimulation (ES) environment.

Stable isotope-labeled carnitine reveals its rapid transport into muscle cells and acetylation during contraction

open access: yesHeliyon, 2023
Carnitine plays multiple roles in skeletal muscle metabolism, including fatty acid transport and buffering of excess acetyl-CoA in the mitochondria. The skeletal muscle cannot synthesize carnitine; therefore, carnitine must be taken up from the blood ...

Isometric contraction induces transient increase of REDD1 expression in non‐contracted muscles partly through glucocorticoids

open access: yesPhysiological Reports, 2023
This study investigated whether muscle contraction induces expression of regulated in development and DNA damage 1 (REDD1), a potent inhibitor of mTORC1, in mice muscle.

A new paradigm for muscle contraction [PDF]

open access: yesFrontiers in Physiology, 2015
Muscle contraction has fascinated lay people and scientists for centuries. However, a good understanding of how muscle contraction occurs seemed only possible once microscopy techniques had evolved to a level where basic structural features, such as the regular cross striation patterns of fibers, could be observed in the late 19th century. In the early

Do differences in levels, types, and duration of muscle contraction have an effect on the degree of post-exercise depression?

open access: yesFrontiers in Human Neuroscience, 2016
We conducted two experiments to determine how differences in muscle contraction levels, muscle contraction types, and movement duration affect degree of post-exercise depression (PED) after non-exhaustive, repetitive finger movement.

Water and Muscle Contraction [PDF]

open access: yesInternational Journal of Molecular Sciences, 2008
The interaction between water and the protein of the contractile machinery as well as the tendency of these proteins to form geometrically ordered structures provide a link between water and muscle contraction. Protein osmotic pressure is strictly related to the chemical potential of the contractile proteins, to the stiffness of muscle structures and ...
