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 for muscles to

Muscle–spring dynamics in time-limited, elastic movements

Both frogs and grasshoppers require elastic elements to achieve their high-power jumping performance [10 the stiffer the series spring required for maximum elastic energy storage. Muscles that load in-series springs over shorter time scales benefit from less stiff springs. At short time scales, muscle force is small owing to low activation

Glycogen

Glycogen Definition. Glycogen is a large, branched polysaccharide that is the main storage form of glucose in animals and humans. Glycogen is as an important energy reservoir; when energy is required by the body, glycogen in broken down to glucose, which then enters the glycolytic or pentose phosphate pathway or is released into the bloodstream.

How tendons buffer energy dissipation by muscle

In the turkey gastrocnemius, the temporary storage and release of energy from tendon to muscle can result in a reduction in the rate at which energy is dissipated by the muscle fascicles. We have referred to this role of tendon as that of a power attenuator, because the peak rate of power input to the muscle is reduced.

6 FAQs about [Energy storage elements in muscles]

Why is elastic energy storage important in muscle and tendon?

Elastic energy storage in muscle and tendon is important in at least three contexts (i) metabolic energy savings derived from reduced muscle work, (ii) amplification of muscle-tendon power during jumping, and (iii) stabilization of muscle-tendon force transmission for control of movement.

What is muscle and tendon energy storage?

Muscle and tendon energy storage represents the strain energy that is stored within a muscle-tendon complex as a muscle and tendon are stretched by the force developed by the muscle when it contracts. This energy may be subsequently recovered elastically when the muscle relaxes.

Which energy form can help reduce muscle work demands?

There is, however, another energy form which may help to reduce muscle work demands: elastic energy. When a material is subjected to a force, F, it deforms. During this deformation, the force moves over a finite displacement, x, and thus does work, F x. This work can be stored as elastic potential energy (E elastic ).
