(a) A typical energy storage and return foot, showing the blades
Energy storage and return (ESR) feet have long been assumed to promote metabolically efficient amputee gait. However, despite being prescribed for approximately 30 yr, there is limited
Energy Storage And Return From Footwear And Biological Struc
Positive Foot + Footwear work (energy return) was significantly greater in Shoe A (0.30 ± 0.09 J/kg) than both other shoes (Shoe B: 0.19 ± 0.08 J/kg, p = 0.001; Shoe C: 0.15 ± 0.07 J/kg, p
A passive mechanism for decoupling energy storage
The variable-stiffness prosthetic ankle–foot (VSPA) with Decoupled Energy Storage and Return cam-based transmission. A rotation of the ankle joint causes deflection of a propped cantilever spring via a cam-based transmission. The

6 FAQs about [Sports energy storage foot]
Does running footwear have energy storage and return?
The result of this study is a framework for qualitatively evaluating energy storage and return related aspects of running footwear. This framework provides a practical tool for footwear developers, researchers, and competition regulators to evaluate the timing, relative magnitude, and location of energy storage and return from footwear.
Does footwear construction influence mechanical energy storage and return?
Footwear construction can also influence the timing of mechanical energy storage and return. In the footwear comparison ( Fig. 4 ), the advanced shoe foot + footwear system started generating positive work sooner (∼40% vs. ∼ 70% stance).
What is energy storage and return prosthetics?
Preliminary energy storage and return prostheses incorporated an elastically deflectable keel in the prosthetic foot aspect. This design would store a portion of energy during the impact of stance initiation with a subsequent release during the terminal aspect of stance.
What is a controlled energy storing and returning foot?
The so-called Controlled Energy Storing and Returning Foot (CESR Foot) was developed to enhance the push-off properties of passive prostheses. CESR feet do not store energy during posture, but use the weight of the body to accumulate energy during initial contact and release energy when needed .
Do intrinsic foot muscles contribute to elastic energy storage and return?
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.
Does the FDB MTU contribute to elastic energy storage within the foot?
We have shown that the FDB MTU contributes to elastic energy storage within the foot. Because of its similar anatomical pathway, it is likely that the plantar aponeurosis was also stretched more as loading increased and shared some of the increased energy storage and return with the FDB tendons.
