Amputee Is German Long Jump Champion

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."

  1. No, no unfair advantage at all... by BitZtream · · Score: 4, Insightful

    From TFA

    Rehm runs and jumps with a specially designed blade that is 15 inches longer than his other leg

    I can't imagine why anyone would accuses him of 'cheating' ...

    The device is like a spring, so it stores energy as well as having extra length and mechanical advantage, and better still its far stronger and requires much more force to break.

    I'm sorry he lost his leg, but there is no why this is 'fair' by any sense of the word.

      I can't speak for long jump, but in high jump your shoes are definately regulated.
      you're not allowed for example to have shoes that have a sole thicker than a certain amount.
      I just looked it up and apparently it's the same for long jump shoes.
      So yes, I don't think springs or a blade qualify as valid shoes in this case (especially if the blade is 18 inches longer than your other leg!).

      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. It really is quite hard to calculate with any precision if his prosthetic is giving him an advantage or if it is simply replacing some of what he has lost.

      Long jumpers jump from the same leg every time - in Markus Rehm's case, his take-off leg just happens to be the prosthetic one.

      Plus (and this is the biggie with regards to all prosthetic appendages IHMO) - he has one leg which effectively cannot get injured. He's less likely to suffer any training setbacks during his build-up to major events. If his prosthetic leg snaps a week before the worlds, he can simply replace it. With a real leg, there'd be no chance for it to heal in time. Hell, he doesn't even have to deal with blisters on one of his feet.

      The leg has a lot of spring due to the tendon and muscle attached at the ankle. With the ankle extended, it does a very good job of storing and releasing energy. That's one reason the runners who don't normally wear shoes do better, they don't get in the habit of heel striking.

      In the prosthetic, the spring is trying to compensate both for the spring action of the tendon and muscle AND the contraction of the calf on takeoff. He doesn't get that last instant energy boost, he has to 'save up' for it in his stride up to the line.

      I doubt this. From what I know of prosthetics the attachment point is prone to all kinds of problems with blisters, rubbing, chaffing, etc...

      This is more of an extended shoe that still connects to the leg which brings up an interesting point.
      If you ban this do you also ban someone who has one leg longer than the other and needs a 2 inch sole? What about an 8 inch sole?
      What about someone who has corrective surgery to fix the length of their leg or someone who has elective surgery to increase the
      length of both legs?

      Currently we seem to not care until they actually come in 1st place then we start asking questions.
      Regardless of the outcome, this is good news for the advancement of prosthetics and people who need them.

  2. We need different divisions by DNS-and-BIND · · Score: 2

    Just like car racing, we need different divisions for athletics. One for stock, unmodified humans like us. No drugs, etc. And the "top fuel" division for prosthetics, hormones, steroids, etc. My interest in several sports (bicycling, weightlifting) has already died because of rampant drug abuse. Heck, if you don't do drugs then you won't even qualify for televised events. It's sort of like F1 racing, it's not really a competition between humans, it's a competition between scientists.

    Ever since the Olympics went professional, it's been boring. Of course, once these two divisions have been established, the athletes will still cheat in the stock division. Because there's money involved. Even the Korean Starcraft players cheat for the same reason.

      Where do you draw the line? Olympic bicyclists have one leg larger than the other. Many other
      professionals like weight lifters, etc... are similiarly deformed. Weird protein shakes and specialized
      diets are the norm. Reinjecting your own blood right before game time is pretty common in some sports.
      It's not a drug or enhancement but clearly is not something that should be allowed. How do you
      regulate these things? What about someone who has a medical condition and needs to take steroids
      or some other drug like an antidepressant that has a side effect of enhanced performance.
      Professional sports for the most part are already twisted into a sport for only accidental freaks of nature
      who in addition to having some lucky physical trait also train round the clock 24/7 with specialized diets
      and specialized exercise routines. We all might be better off if we just say anything goes and see exactly
      how far we can push technology and the human body instead of pretending that all athletes are normal

  3. Different equipment, different categories by pmontra · · Score: 3, Insightful

    Eventually prosthetics will get so good that they'll let athletes achieve much better results than any unmodified human. When it happens everybody will see that the only way to go is different categories for different equipments. We are bound by compassion and politically correctness until we get to that point, so how to address this problem now? Call me hard hearted but I'd still apply my reasoning and enforce different categories right now even if we are in doubt of who's getting an advantage at the moment.

    If there's a distinct non-human advantage to them, yes. Most sports are extremely tightly regulated, mainly I've looked at the Nordic sports and for example the jump suit used in ski jumping is highly regulated. Likewise in ice skating, they proved some years ago a "Donald Duck" like suit would improve skate times. It was banned. The support biathlon athletes can get while shooting is likewise regulated. The rules themselves are arbitrary, as long as they're equal for everyone. Why it is "three strikes, you're out" in baseball? Couldn't it be one strike? Five strikes? Sure it could, but the game says three. And then you compete under the rules of the game. Everything else is the other way around, they're allowed to wear baseball caps because everyone can wear one and it doesn't favor anyone in particular. You can't call ut unaided because bicyclists obviously outpace runners, pole vaulters outjump high jumpers and so on but the aid is considered neutral. Anything that isn't you ban.

  8. He takes off using the prosthetic leg... by HockeyPuck · · Score: 4, Informative

    If you watch the jump carefully you'll notice that he takes off (launches) from the prosthetic leg. I wouldn't be complaining too much if he took off from his real leg.

    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.

    As a side note, I would assume there is no "fatigue" or decrease in "springiness" of the prosthetic between his first, second and third jumps. He could always show up to an event with a brand new prosthetic.

    He's cheating.
