The invention relates to a portable device and a method for monitoring the performance a sportsman performing a plurality of motor acts, such as golf swings. The device comprises at least one sensor providing an output signal, the sensor being responsive to body movements of the sportsman. A signal processing unit is used for extracting data on the course of each of the plurality of motor acts from the sensor output signal, and a computing unit is used for determining, based on the data on the course of the plurality of motor acts, at least one characteristic number describing the repeatability of the motor act. By the means of the invention, the handicap number of the golfer can be predicted with good accuracy by monitoring several his or her subsequent swings.
