[BTS P6000] Use of Optoelectronic Systems for the Analysis of Technique in Trials

Abstract:

 

Optoelectronic systems represent the gold standard of technologies used in the motion analysis for the evaluation of kinematics. Trials, a specialty of mountain biking, differ a lot from other cycling specialties, because in addition to pedaling, they require jumping techniques to overcome obstacles that involve the whole body.

 

In this sport, more than in others, the evaluation of technical movements using optoelectronic systems goes far beyond simply assessing the biomechanics of pedaling or the correct positioning on the bike. Starting from a previous study conducted with video analysis technique applied to the lateral jumping technique, two versions of this technique were compared, considering the kinematics of the act, taking into account both the data relating the subject and the bicycle.

 

The joint angles of the lower limbs and the angles described by the bicycle on the three space plane were considered. The major differences have been found in the “leap over” phase, about the bending of the lower limbs and the angles described by the bicycle.
