Amputee Is German Long Jump Champion 175
hweimer (709734) writes "German long jumper Markus Rehm has written sports history yesterday, becoming the first disabled athlete to win a national able-bodied championship. His jump to 8.24 meters put him on the 9th place of the current season rankings and make him egligible to compete in the upcoming European championships, further sparking the debate whether his prosthetic leg provides him with an unfair advantage."

The human leg provides a spring effect as well. He is missing all of the springiness of his achilles tendon. He is also missing all of the contribution of his calf muscles to the jump.

Look at the kangaroo, a kangaroo has a very long Achilles tendon. This allows them to be very efficient in jumping buy storing up so much energy when it stretches out like a rubber band enabling them to jump very far with very little effort. Humans on the other hand, have very short achilles tendons and therefore do not have this mechanical advantage.
When landing, the impact force and weight of the this guy is absorbed by active elastic stretch of the prosthetic. When he jumps, the weight is accelerated by a recoil force due to elastic recoil of the the prosthetic. This recoil force is much greater than that of what our our achilles tendon plus the active contraction of our calf muscle can do.
This guy has the equivilant of a 15inch long achilles tendon. As if you look at the video when he actually makes the jump, you'll see the prosthetic "foot" is bent 90 degrees from it's normal angle. The human achilles tendon is a) not 15in long and b) doesn't bend 90 degrees.
