In the last years the Paralympic competitions are getting more and more popular. That is especially true for kayaking, which gets a great deal of news coverage.

The currently used classification methods are not accurate enough and give the athletes opportunities to cheat to get in better groups. As with every professional sport, the victory means serious monetary reward. For the fairness of the competitions the athletes with the same performance should be classified in same groups, and compete with each other. Instead of the current classification methods new, modern objective classification methods are needed that take into account multiple parameters.

In the orthopedic clinic of the Semmelweis University a new, modern motion analyzing laboratory opened in 2011. In this laboratory, based on reflective markers and IR cameras, the 3D positions of the markers can be tracked in real time. The muscle activity can be also measured using an EMG machine. Using this system the performance of the athletes can be measured and analyzed objectively.

With the permission of the lab coordinator the measurements were done in that laboratory. For the duration of the measurements from the Hungarian Paralympic Comity we received a kayak ergometer, which was upgraded with additional sensors. This way the foot pressure of the athletes was also recorded. The measurements happened in 2014-2015.
