On Data Mining Technique for Differentiation Condition of Football Players Using of Arterial Oscillography.

In this paper for the first time decision tree for differentiation of functional states (before and after the match, before and after the training) of professional football players and football amateurs based on arterial oscillography data (Vakulenko D.V., Vakulenko L.O.) was constructed, characteristic adaptive portraits were revealed, indicating a significant place of psycho-emotional stress. The work uses the shoulder compression by the cuff when measuring blood pressure to assess the adaptive mechanisms of the body. Separate decision trees were built for each type of research, as well as for their totality. The error of the algorithm was investigated.
