6 FAQs about [Achilles tendon storage and release energy]

How much energy does the Achilles tendon release?

Their conclusion: the Achilles tendon stores and releases only about 2% of the energy needed for each stride. That's a pretty big deviation from previous estimates.

Why is the Achilles tendon important?

The Achilles tendon in particular also differs markedly from the shorter, stiffer foot extensor tendon found in other primates (Vereecke et al ., 2005 ), suggesting that it plays an important locomotor role that is distinct from that of our closest relatives and hinting at its evolutionary importance.

Are Achilles tendon work loops positive or negative?

It’s positive to be negative: achilles tendon work loops during human locomotion. PLoS ONE 12, e0179976 (2017). Raichlen, D. A., Armstrong, H. & Lieberman, D. E. Calcaneus length determines running economy: implications for endurance running performance in modern humans and Neandertals. J.

Do stiff Achilles tendons affect running economy?

The revised estimate doesn't mean Fletcher doesn't think the Achilles is important to running economy. In fact, there's a significant body of research suggesting that stiffer Achilles tendons correlate with better running economy. But the mechanisms may be different than we thought, he argues.

Does moment arm length determine spring-like behavior of the Achilles tendon?

We find that moment arm length significantly determines the spring-like behavior of the Achilles tendon, as well as estimates of mass-specific tendon stress and elastic energy storage at running and sprinting speeds.

How important is tendon energy recoil in running?

Besides the important tendon energy recoil during the propulsion phase (7.8 to 11.3 J), we found a recoil of elastic strain energy at the beginning of the stance phase of running (70–77 ms after touch down) between 1.7 ± 0.6 and 1.9 ± 1.1 J, which might be functionally relevant for running efficiency.
