How tendons buffer energy dissipation by muscle
During rapid energy-dissipating events, tendons buffer the work done on muscle by temporarily storing elastic energy, then releasing this energy to do work on the muscle. This elastic mechanism may reduce the risk of muscle damage by reducing peak forces and lengthening rates of active muscle. Keywords: Muscle, tendon, elastic energy, energy
Elastic energy storage and the efficiency of movement: Current
Labonte and Holt provide a comparative account of the potential for the storage and return of elastic stain energy to reduce the metabolic cost of cyclical movements. They consider the properties of biological springs, the capacity for such springs to replace muscle work, and the potential for this replacement of work to reduce

Elastic energy storage in muscle and tendon is important in at least three contexts (i) metabolic energy savings derived from reduced muscle work, (ii)
Review Muscle-tendon stresses and elastic energy storage
Fig. 1 A shows the anatomical organization of the muscle-tendons and ligaments analyzed for elastic energy storage in the forelimb (superficial digital flexor (SDF); deep digital flexor (DDF); ulnaris lateralis (ULN) and flexor carpi ulnaris/radialis (FCU/R); and metacarpal suspensory ligament (S-Lig)) and hindlimb (plantaris, PL—also

Elastic energy storage in the shoulder and the evolution of high
Elastic energy storage at the shoulder also augments the generation of joint velocity and power at the elbow. During acceleration, the elbow extends at very high angular velocities (2,434±552°/sec) despite large amounts of negative power and work (−246±63J), indicating that the triceps alone are not powering this rapid extension ( Fig. 2 ).
Movement Strategies for Countermovement
In order to truly understand how additional body mass affects the storage of energy within the lower limb tendons, more direct measures of muscle activation and shortening are required.
Intrinsic foot muscles contribute to elastic energy storage and
In this paper, we present the first direct evidence that the intrinsic foot muscles also contribute to elastic energy storage and return within the human foot. Isometric contrac-tion of the flexor digitorum brevis muscle tissue facilitates tendon stretch and recoil during controlled loading of the foot.
Intrinsic foot muscles contribute to elastic energy storage and
The human foot is uniquely stiff to enable forward propulsion, yet also possesses sufficient elasticity to act as an energy store, recycling mechanical energy during locomotion. Historically, this dichotomous function has been attributed to the passive contribution of the plantar aponeurosis. However, recent evidence highlights the potential
Role of the phosphocreatine system on energetic homeostasis in skeletal and cardiac muscles
The phosphocreatine "shuttle" system In 1970, Gudbjarnason et al. noted that in skeletal muscle submitted to ischemia, contractile activity was interrupted when PCr was depleted, despite the levels of ATP being reduced by only about 20%. The authors suggested that intracellular ATP may not be homogeneously distributed in muscle cells
Contribution of elastic tissues to the mechanics and energetics of
Actomyosin cross-bridges, actin and myosin filaments, titin, and the connective tissue scaffolding of the extracellular matrix all have the potential to store and
Intrinsic foot muscles contribute to elastic energy storage and return in the human foot
This mechanism has long been considered passive in nature, facilitated by the elastic ligaments within the arch of the foot. In this paper, we present the first direct evidence that the intrinsic foot muscles also contribute to elastic energy storage and return within the human foot. Isometric contraction of the flexor digitorum brevis muscle
Intrinsic foot muscles contribute to elastic energy storage and
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
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 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
Tuned muscle and spring properties increase elastic energy storage
In this study, we examined the energy storage capacity of plantaris longus MTUs of three species of frogs that have been shown to differ in jumping power (Roberts et al., 2011) to assess variable tuning of muscle and spring stiffness and energy storage capacity.
Tuned muscle and spring properties increase elastic energy storage
Effective tuning of muscle and spring force capacities is essential for effective function of LaMSA systems (Ilton et al., 2018).Any change in muscle force should be accompanied by a tuned change in spring stiffness to
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.

Glycogen (black granules) in spermatozoa of a flatworm; transmission electron microscopy, scale: 0.3 μm. Glycogen is a multibranched polysaccharide of glucose that serves as a form of energy storage in animals, [2] fungi, and bacteria. [3] It is the main storage form of glucose in the human body.
Elastic energy storage and the efficiency of movement
The elastic potential energy stored in a perfectly linearly elastic material is: (1) E elastic = ½ kx 2 = ½ F 2 / k = ½ Fx. A spring''s stiffness is determined by its geometry and the properties of the material it is made of. Stiffness can be converted into a geometry-independent material property, the elastic modulus, by appropriate
Active leg stiffness and energy stored in the muscles during maximal counter movement jump
The active elements (activated muscles) can actively do work during the CMJ that makes the energy returned greater than the energy stored. This could explain why the energy stored and returned during the eccentric and concentric action were not correlated with the leg stiffness, but the active work was found in this study to be
