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.

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.

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.

Muscle contraction. [PDF]

Novartis Foundation symposium, 1998
Understanding muscle contraction goes to the heart of one of the fundamental questions posed by classical philosophy, namely the nature of the pi nu epsilon upsilon mu alpha psi nu chi iota kappa omicron nu. The nature of 'understanding' has altered greatly during the last two millenia, particularly in response to the development of the concept of ...

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

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 ...

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

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 ...

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

Applied 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.

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

Physiological 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.

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

Heliyon, 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 ...

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

Frontiers 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.
