Elastic energy storage in tendons

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.

The Role of Mineral in the Storage of Elastic Energy in Turkey Tendons

The viscous component for mineralized turkey tendons was about the same as that of self-assembled collagen fibers aged for 6 months, a result suggesting that addition of mineral does not alter the viscous properties of tendon. It is concluded that elastic energy storage in tendons involves direct stretching of the collagen triple-helix

Elastic energy storage in tendons: mechanical differences related

The differences in material properties between mature flexor and extensor tendons are correlated with their physiological functions, i.e., the flexor is much better suited to act as an effective biological spring than is the extensor. We investigated the possibility that tendons that normally experience relatively high stresses and function as springs during locomotion, such

Elastic Energy Stores in Running Vertebrates

It is shown by means of a generalized model that muscles and tendons could both be important as elastic energy stores for large mammals, and that these conclusions presumably apply to large mammals in general. Large mammals save much of the energy they would otherwise need for running by means of elastic structures in their legs. Kinetic and potential energy, lost at one

It is concluded that mineralization is an efficient means for increasing the amount of elastic energy storage that is required for increased load-bearing ability needed for locomotion of adult birds. Animals store elastic energy in leg and foot tendons during locomotion. In the turkey, much of the locomotive force generated by the gastrocnemius muscle is stored as elastic energy during

Furthermore, these alterations in elastic properties occur to a significantly greater degree in the high-load-bearing flexors than in the low-stress extensors. At maturity the pig digital flexor tendons have twice the tensile strength and elastic modulus but only half the strain energy dissipation of the corresponding extensor tendons.

Elastic Energy Storage

Muscles and tendons play a significant role in elastic energy storage, where tendons can act like springs, storing energy during the eccentric phase of movement. Proper technique in exercises like squats and jumps can improve the efficiency of elastic energy utilization, resulting in better overall strength output.

Tendons Store Elastic Energy — Biological Strategy

For example, grasshoppers store energy as potential energy in an elastic material in their tendons. When they need to jump, that energy converts into kinetic energy, providing the force needed to escape predators. The presence of elastic energy storage and recoil in submaximal jumps may also be informative in future investigations into the

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.

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.

Yet, the proposed role for elastic energy storage and recovery is the reduction of muscle work, and at least for one study of frog muscles, it does not appear that replacing muscle work with tendon work reduces cost (Holt et al., 2014). We have more to learn about the energetic significance of elastic energy storage and recovery in cyclic motions.

One common explanation for why AEL should enhance power is that increased load in the eccentric phase amplifies elastic energy storage in the tendon and aponeurosis, which can be released in the concentric phase . For instance, AEL CMJ may result in greater force generation in the descent to decelerate the added mass or resist the added force
