Opinions differed on the tactical game differed after sprintstafetten. But the swede Oskar Svensson, who went in teams with Calle Halfvarsson, said that he liked it.
– There will be no more tactics than this, and I think it is so sprint should be, ” he said afterwards.
And it was not only at the height of the last utförskörningen as the tactical game turned out. The whole sprintstafetten was a waiver of different arrangements to end up in the right position to save power to the right locations.
Tech Research Centre at Mid sweden university in Östersund, sweden, have studied how much energy and force of a skier saving by staying in the back of another rider at different speeds.
the Study shows that gentlemen will save four percent in energy by lying in the back of the rider in front of tävlingshastigheter. Ladies save two to three per cent by doing the same.
” We have studied the poling in the classic style. When we run this study, we have had two rullskidåkare at the same time on the walkway. The one that goes on the front part of the band and the other that goes behind it, ” says Mats Ainegren, senior lecturer in sports technology at the Sports Tech Research Centre at Mid sweden university in Östersund.
fall 2017 went on the study with several different tests in which ten men and ten women subjects.
– We chose a range of speeds for the ladies and gentlemen, from the motionärshastighet to their tävlingshastigheter. When they are at their tävlingshastigheter save the most energy if they are behind someone who pulls, as for example in the Vasaloppet. When they are situated on the lower speed there was no merit in principle, because the air resistance becomes so small, ” says Mats Ainegren.
He says a big part of skiing in the biathlon and cross-country skiing take place in conjunction with the other racers.
the Contestants go near each other both in the masstarter and in the race with interval start. The latter type of competition often goes in several turns, so riders who start later in the fields, together with the which blends. The going a little slower can then take back on faster and go just as fast but with less energy consumption.
appeared four years ago, when Östersund got a wind tunnel to work with. Something that had been requested to research a longer period of time.
” We have always wished us a lab where we could get with us is not hot, which is often a significant factor in many sports. The gigantic moving walkway in the wind tunnel means that you can have multiple rullskidsåkare and cyclists on the tape at the same time.
” Everyone who participated was elitutövare and have received the results of their own. We spread it both within the scientific community, and then back to the sport, to those who participated and to the coaches.
