Swedish Study on the Effects of Drafting and Air Resistance in Nordic Ski Racing

MITTUNIVERSITY in Ostersund has been investigating a study on the effects of drafting and air resistance in Nordic ski racing. Researchers are trying to figure out how much energy and power cross-country skiers can save when they tuck in behind other skiers. Researchers and athletes have reason to believe this can make a huge difference in mass start races.

An ongoing research study is looking to see how much energy and power can be saved by skiing behind others. “Drafting” is not a new concept, and proper drafting techniques are commonly practiced in cycling, however, to date cross country ski sports scientists have yet to prove its relevancy for Nordic racing.

“I absolutely believe that you can benefit from the study, since you can not only focus on how much you can save on skiing behind but also for the one in the very front – how can I optimize my race to give as little benefit as possible to those behind, says Mats Ainegren.

“We want to look at different speeds, because the air resistance increases at higher speeds, and then we want to see what speed has a significant impact,” says the associate professor of sports technology, Mats Ainegren.

The study called for 10 men and 10 women of elite and semi-professional racers, and will release the results in the fall of 2017, just in time for the 2017-2018 race season.

“It’s no news that it’s easier to ski behind, but I think, on the other hand, that you can develop the technology to be first and not loose anything. Sometimes it difficult to be second and third, – so the trick is to find the right method.” – says Jerry Ahrlin.
