Insomnia impairs muscle function via regulating protein degradation and muscle clock [PDF]
arXiv, 2023 Background: Insomnia makes people more physically unable of doing daily duties, which results in a lack of strength, leads to lacking in strength. However, the effects of insomnia on muscle function have not yet been thoroughly investigated. So, the objectives of this study were to clarify how insomnia contributes to the decrease of muscular function ...

Muscles, 2023 Strenuous exercise involving eccentric muscle actions induces skeletal muscle damage resulting in delayed onset muscle soreness (DOMS). Antioxidant supplementation, such as astaxanthin (AX), may alleviate muscle injury following intense exercise.

Neural self-organization for muscle-driven robots [PDF]
arXiv, 2023 We present self-organizing control principles for simulated robots actuated by synthetic muscles. Muscles correspond to linear motors exerting force only when contracting, but not when expanding, with joints being actuated by pairs of antagonistic muscles.

The energy of muscle contraction. II. Transverse compression and work [PDF]
, 2020 In this study we reproduced this compression-induced reduction in muscle force through the use of a three-dimensional finite element model of contracting muscle. The model used the principle of minimum total energy and allowed for the redistribution of energy through different strain energy-densities; this allowed us to determine the importance of the ...

W Prime: Evidence-Based Proposal for a New Predictor of Gait Speed in Older Women
Muscles, 2023 Background: The hyperbolic torque-duration curve depicts critical torque (CT) and W prime (W′), with the curve’s asymptote representing CT as the boundary between heavy- and severe-intensity domains.

Proceedings of the National Academy of Sciences, 2015 Significance The force generated by a muscle decreases when its contraction velocity increases. This rheology follows the heuristic Hill’s equation. Here, we design and study a capillary analog in which the myosin–actin interaction is replaced by the wetting affinity between a Newtonian silicone oil and a steel rod.

Diagnostic Testing in Suspected Primary Mitochondrial Myopathy
Muscles, 2023 The diagnosis of primary mitochondrial myopathy is often delayed by years due to non-specific clinical symptoms as well as variable testing of mitochondrial disorders.

Agent-based Modeling and Simulation of Human Muscle For Development of Human Gait Analyzer Application [PDF]
arXiv, 2022 Despite the fact that only a small portion of muscles are affected in motion disease and disorders, medical therapies do not distinguish between healthy and unhealthy muscles. In this paper, a method is devised in order to calculate the neural stimuli of the lower body during gait cycle and check if any group of muscles are not acting properly.

Muscle spindles of the rat sternomastoid muscle
European Journal of Translational Myology, 2018 The sternomastoid (SM) muscle in rodents presents a peculiar distribution of fiber types with a steep gradient from the ventral, superficial, white portion to the dorsal, deep, red region, where muscle spindles are restricted. Cross section of the medial longitudinal third of the rat SM contains around 10,000 muscle fibers with a mean diameter of 51.28±

Muscles, 2023 We have previously shown that hypothermia leads to an increase in the synaptic modulating effects of ATP but not of adenosine in several different animal skeletal muscles.
