The method pertains to monitoring movements of a human to determine types of human motor activity. Signals generated by a three-component accelerometer attached to human body are recorded and used for calculating acceleration vector magnitudes, forming a time array of acceleration vector magnitudes, and identifying its extrema. Duration of separate motor acts and the differences between adjacent extrema of acceleration vector magnitude for each motor act are determined by counting, consecutively from one extremum to another, the number of extrema equal to a reference number of extrema in at least one pattern, which is pre-formed for a certain type of motor activity and characterized by a specific reference number of acceleration vector magnitude extrema, a specific reference value of motor act duration, and specific reference values of difference between adjacent extrema of acceleration vector magnitude. A determination is made of a type of motor activity.
