CLASSIFICATION A SENSORIMOTOR TASK LEVEL OF COMPLEXITY FOR ATHLETES BASED ON PHYSIOLOGICAL INDICATORS USING MACHINE LEARNING METHODS

The study aimed to identify the most sensitive autonomic indicators reflecting the level of complexity of the sensorimotor task performed by athletes using various machine learning methods (classification algorithms). As tasks of two levels of difficulty, we used the audio-motor synchronization task: to tap in synchrony with a metronome rhythmic sound (a simple task) and to tap the same rhythm without auditory cues (rhythm memory task, a complex task). Heart rate, respiratory parameters, skin conduction, and EEG were recorded. The most accurate classification was demonstrated by the Classification and Regression Trees (C&RT) model – the error was only 18.29%.
