Preservation of aerobic fitness and skeletal muscle strength through exercise training can ameliorate metabolic dysfunction and prevent chronic disease. These benefits are mediated in part by extensive metabolic and
How tendons buffer energy dissipation by muscle
Abstract. To decelerate the body and limbs, muscles actively lengthen to dissipate energy. During rapid energy-dissipating events, tendons buffer the work done on muscle by
Exercise metabolism and adaptation in skeletal muscle
As a primary site of nutrient storage, energy use and locomotion, skeletal muscle is central to the impact of physical activity on human health.
Measurements of muscle stiffness and the mechanism of elastic storage of energy
Measurement of work absorption by the muscle with a full length of free tendon and when the tendon had been shortened, showed that with the shortened tendon a larger proportion of movement occurred in the muscle fibres, producing a steep rise in work absorptionBy the muscle and a consequent increase in energy loss. 1. A kangaroo hopping above a
Effects of Elastic Energy Storage on Muscle Work and Efficiency
The tendons in modern horses are highly specialised in the storage of elastic energy (Biewener, 1997; Wilson et al., 2001). Janis and Bernor (2019) also proposed that the monodactyl limb evolved

In-series tendon can store energy from muscles during contraction of the muscles, as in frog jumping, but energy storage within intramuscular springs requires
Elastic energy storage and release in white muscle from dogfish
ABSTRACT. The production of work by the contractile component (CC) and the storage and release of work in the elastic structures that act in series (the series elastic component, SEC) with the contractile component were measured using white muscle fibres from the dogfish Scyliorhinus canicula. Heat production was also measured because the
Intrinsic foot muscles contribute to elastic energy storage and
The flexor muscles of the toes are generally helpful in supporting the foot arch and are thought to contribute to force generation at the metatarsophalangeal joints [3,16,17]. A vertical load of
Intrinsic foot muscles contribute to elastic energy storage and return in the human foot
When active, the FDB muscle fascicles contracted in an isometric manner, facilitating elastic energy storage in the tendon, in addition to the energy stored within the plantar aponeurosis. We propose that the human foot is akin to an active suspension system for the human body, with mechanical and energetic properties that can be actively
How Tendons Buffer Energy Dissipation by Muscle : Exercise and
by Muscle. To decelerate the body and limbs, muscles lengthen actively to dissipate energy. During rapid energy-dissipating events, tendons buffer the work done on muscle by storing elastic energy temporarily, then releasing this energy to do work on the muscle. This elastic mechanism may reduce the risk of muscle damage by reducing peak forces
Collagen Homeostasis and Metabolism
The musculoskeletal system and its collagen rich tissue is important for ensuring architecture of skeletal muscle, energy storage in tendon and ligaments, joint surface protection, and for ensuring the transfer of muscular forces into resulting limb movement. Structure of tendon is stable and the metabolic activity is low, but mechanical
What Is Glycogen? How the Body Stores and Uses Glucose for
Increasing glucose signals to the pancreas to produce insulin, a hormone that helps the body''s cells take up glucose from the bloodstream for energy or storage. Activation from insulin causes the liver and muscle cells to produce an enzyme called glycogen synthase that links chains of glucose together. Delivering glycogen molecules
Storage of elastic strain energy in muscle and other tissues
Storage of elastic strain energy in muscle and other tissues. R. Alexander, H. Bennet-Clark. Published in Nature 1 January 1977. Biology, Materials Science. TLDR. The elastic materials involved include muscle in every case, but only in insect flight is the proportion of the energy stored in the muscle substantial. Expand.
Tuned muscle and spring properties increase elastic energy storage
A muscle that contracts against relatively compliant elastic structures (left) would store approximately 72% of the maximal energy. Thus, tuning spring stiffness to muscle force capacity should maximize energy storage. (B) The force–length relationship shifted upward for a muscle modified for increased force capacity.
Allometry of muscle, tendon, and elastic energy storage capacity in mammals
Thus the maximum amount of stress a tendon may experience in vivo, as indicated by the ratio of muscle and tendon cross-sectional areas, increases with body mass in digital flexors and ankle extensors. Consequently, the capacity for elastic energy storage scales with positive allometry in these tendons but is isometric in the digital extensors
