Abstract

A pilot is presented to evaluate a helmet mounted vibrotactile feedback system (VFS) for managing head position during cycling by feedback to a subject when its head deviates from a preset aerodynamic position. The VFS measurements are validated with a Vicon motion capturing system. The effect of the VFS is compared with verbal instructions only. In 89.66% (P = 0.15) of all measurements, the VFS value is in accordance with the Vicon system. In 83.33% of the cases, the sensor correctly leads the subject to the predefined position after perturbation of the position. Changing the margin of error of VFS has little influence on the improvement of attaining the predefined position. The sensor accuracy and efficiency of retaining or resumption the predefined reference position indicates that it can be usable for time trialists, triathletes and track cyclists in attaining their aerodynamic head position.
