Tendon elastic 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. The elastic elements of a muscle.

Tendon

Energy Storage. Tendon can play a significant role in efficient locomotion. When tendon is stretched it stores potential energy that can be recovered as work as the tendon is released. The characteristics of tendon allow 80–95% of this energy to be recovered. Wallabies use elastic storage in the ankle flexors during hopping . When the foot

Tuned muscle and spring properties increase elastic energy storage

In frogs, the plantaris longus muscle–tendon unit (MTU) is an important site of elastic energy storage (Astley and Roberts, 2012; Astley and Roberts, 2014). Here, we used isolated muscle preparations of the plantaris longus MTU to assess the tuning of muscle force capacity and spring properties.

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,

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.

Elastic energy storage across speeds during steady-state

Small bipedal hoppers, including kangaroo rats, are not thought to benefit from substantial elastic energy storage and return during hopping. However, recent species-specific material properties research suggests that, despite relative thickness, the ankle extensor tendons of these small hoppers are considerably more compliant than had been assumed.

the elasticity of the achilles tendon provides an important mechanism: namely, the storage and release of elastic strain energy, which improves the economy and performance of motion (1, 2, 6, 25).Less tendon stiffness results in greater tendon elongation and greater elastic strain energy storage under a given extent of muscle force.
