Elite skier test their limits

Chalmers University of Technology

The super skier Max Novak, who is probably the world's best roller skier and who during the summer has won great victories in both Sweden and Norway, visited Chalmers and tested in the physiology lab, which is located in a brand-new learning environment that will soon be inaugurated ​Novak was there to test the limit of how fast he can ski under controlling shapes. Dan Kuylenstierna, associate professor at Chalmers, collected measurement data that shows how each part of the body works to reach these speeds.

Max Novak, who is used to intensive sessions, thinks the lab is good for doing tests.
"It's really good with these wide, fine bands, with cameras everywhere. There is good access here in Gothenburg," says Max Novak.
The lab consists of a large treadmill that can be tilted 25% at a speed of 50km/h. The band is suitable for skiing, running, roller skiing, inline skating, gait analysis and cycling. All around the lab are high-speed cameras and motion tracking equipment. To study cycling, in addition to the belt, there is a calibrated cycle ergometer that allows you to test work ability and movement patterns. The physiology lab is used for various studies and experiments, where measurement data is collected for the analysis of human movement.
Even robots and smaller electric vehicles can be tested on the belt.
"The measurement data can be used, for example, to train algorithms to recognize movement patterns. This will be useful, among other things, in teaching but also in research," says Dan Kuylenstierna.
