Abstract: A computer-implemented method for adapting a training program of a user, including: storing a database including measurement data of physical exercises the user has performed, the measurement data including at least one of heart activity measurement data and motion measurement data; receiving a user input to select a weekly template for the training program, the weekly template including a training schedule including a plurality of pre-programmed repeating exercises on the weekly template; receiving a user input indicating a repeating exercise the user indicates to perform outside the training program; acquiring, from the database on the basis of the user input indicating the repeating exercise, measurement data of past one or more physical exercises of the repeating exercise; determining, on the basis of the measurement data, a training effect of the past one or more physical exercises and determining at least one repeating physical exercise of the training schedule providing a training effect closest to the

Abstract: A computer-implemented method for providing training guidance in connection with a physical exercise includes: measuring, by using a heart activity sensor, heart activity of a user during a physical exercise; measuring, by using a bioimpedance measurement sensor, bioimpedance of the user during the physical exercise; computing, by a processing circuitry, a stroke volume from the bioimpedance synchronized to a cardiac cycle of the user by using the measured heart activity; computing, by the processing circuitry, training intensity by using at least the computed the stroke volume; comparing, by the processing circuitry, the training intensity with at least one threshold; and outputting at least one training guidance instruction on the basis of the comparison.

Abstract: A method of estimating a stress level of a human by an apparatus using heart activity measurement data includes: executing a breathing exercise application by the apparatus, starting a breathing exercise of the breathing exercise application and outputting, during the breathing exercise, breathing instructions to a user of the apparatus; acquiring a set of heart activity measurement data samples measured by a heart activity sensor from the user during the breathing exercise; computing a set of inter-heartbeat interval samples of the set of heart activity measurement data samples; computing a cardiac coherence of the user during the exercise from the set of inter-heartbeat interval samples; measuring a respiratory rate of the user during the breathing exercise; computing a score of the breathing exercise on the basis of the respiratory rate and the cardiac coherence, the score indicating a stress level of the user; and outputting the score through an interface of the apparatus.
