Anordning och förfarande för monitorering av simningsprestation

摘要

The invention relates to a device and method for monitoring a swimming performance. The device comprises one or more motion-sensitive sensors for providing motion data characteristic to the motion of the swimmer during said swimming performance and a computing unit adapted to detect body motions from said motion data using predefined criteria. According to the invention the computing unit comprises means for calculating a plurality of correlation factors depicting correlation of motion data between successive body motions detected, means for storing the correlation factors as a time series, and means for determining one or more parameters characteristic to the swimming performance based on said correlation factors stored. The invention can be used for robust determination of swimmer's turns, distance swum or swimming style, for example.
