This is an old problem for ski-jumping and it dates back to the time in which ski-jumpers started "flying" from the hill instead than simply "falling" from it. If you want to fly long, you have to weigh little.
New rules and new systems of points have tried in the past and will try in the future to change this situation, but right now ski-jumping seems still to be a sport for skinny people, maybe too skinny.
The last confirmation to this idea comes from the declarations of Martin Schmitt, former number one of this sport. Schimtt admitted that in the last years he had to eat very little to limit his weight and "fly" longer, even if this attitude had bad consequences on his health and triggered in him a "chronic fatigued".
"If I'm not in good physical shape right now is also because for the last years I had always to stay right on the limit of my normal body-weight. It is a risk I had to run if I wanted to be competitive in this sport. To feel better, I should weigh four kilos more than what I do today, keeping the same weight I have when I'm not competing. In this way I could train without feeling so tired. The problem is that with two or three more kilos, I would jump five or six meters shorter."
To recover from this "chronic fatigued", Schmitt decided on Suday to take a break from the competitions to try to get in better form for the Olympics of Vancouver.
