Storage and utilization of elastic energy in vertical jump

Does increased jump height increase energy storage?

Based on these results, we infer that there was additional energy stored within the AT as a consequence of added mass applied to the body and that this additional energy storage did not occur with increasing jump height.

Do jumpers store elastic energy in the Achilles tendon?

Previous studies have demonstrated an important contribution of elastic energy stored within the Achilles tendon (AT) during jumping. This study aimed to alter energy available for storage in the AT to examine changes in how jumpers distribute work among lower limb joints.

Does submaximal jumping reduce dissipation of energy at lower jump heights?

They concluded that during sub-maximal jumping to increasing jump heights, countermovement depth and rotation of large proximal segments were increased while contribution of work at the ankle was decreased 1. This was considered a strategy that minimised dissipation of energy at lower jump heights.

Does the eccentric phase increase VJ height?

The SSC in general has the storage of elastic energy during the eccentric phase, which will be released as kinetic energy during the concentric phase. However, there are 2 important distinctions with the amount of time during the eccentric phase increasing an athlete’s VJ height.

How do we manipulate the mechanical work requirements of jumping?

To examine this we manipulated the mechanical work requirements of jumping in two different ways: (1) Body Mass Paradigm (BMP) - Altering body mass (for a constant jump height) to manipulate the work required for jumping; (2) Jump Height Paradigm (JHP) - Altering jump height to provide a comparable manipulation of total work.

How does tendon compliance affect jump height?

Increasing tendon compliance in the model led to an increase in elastic energy storage and utilization, but it also decreased the amount of energy delivered by the contractile elements to the skeleton. Jump height therefore remained almost the same for both jumps.
