Runners may consider measuring their heels.
The shorter the time, the more successful they may be.
The same is true of Melanie Scholes of Free University in Amsterdam, Netherlands, and his colleagues.
They used mathematical models of legs to study the effect of heel length on long-lasting strength
Long distance running.
At a given speed, a lower energy consumption rate usually means that someone can run further.
Scholz's team wanted to know if this efficiency was related to the elastic energy stored in the Achilles tendon.
