Event-based measurement of power in sport activities by means of distributed wireless sensors

This paper presents a event-based method to evaluate the motor skills and abilities needed to produce an effective performance in judo. Judo is a combat sport. The performances in this sport are complex to be analyzed due to the interaction with other athletes and due to the large number of different situations that can happen during a competition. Moreover, there is a the large number of factors that are related to the performance. The extreme variability of the situations and their high dynamism, make it difficult to define precisely the psychomotor characteristics that any athlete must have to be effective during a judo competition. The use of distributed sensors allows to comprehensively describe the characteristic features of each individual athlete, giving the chance to compare of motor skills that apparently seemed poles apart.
