Getting the angles straight in speed skating: A validation study on an IMU filter design to measure the lean angle of the skate on the straights

To assist speed skaters in improving their skating performance, we would like to provide them with real time feedback on the orientation of the skate within a single stroke. While of course the forces generated by the skater on the ice determine the acceleration of the skater, the orientation of the skate determines in which direction this...

Giving the force direction: Analysis of speed skater push off forces with respect to an inertial coordinate system

Pushoff in speed skating requires an extensive motion strategy. During speed skating the skater continuously changes the lean and steering angle of the skate and therewith the direction of push-off, The forces in an inertial coordinate system can give insight into what amount of the push-off force is directed into the forward motion. In this...

Balance and control of a rear-wheel steered speed-record recumbent bicycle

The goal of the Human Power Team from the TU Delft and the Free University of Amsterdam is to break the world speed record in unpaced cycling (Sam Whittingham, 133.28 km/h). The design of such a faired recumbent bicycle is a challenge. The Delft design, called VeloX (Human Power Team (2013)), is a fully-faired monocoque front-driven recumbent...

Preliminary results from a field experiment on e-bike safety: Speed choice and mental workload for middle-aged and elderly cyclists

To study the safety of e-bikes for the elderly, an experimental field study was conducted, using instrumented bicycles and comparing two age groups: older cyclists, n= 29, mean age = 70, SD = 4.2 and middle-aged cyclists, n = 29, mean age = 38, SD = 4.3. All were regular cyclists. They rode a fixed route with a length of about 3.5 km: once on an...
