Patent ID: 8512238

Claim:
A data processing device comprising: a digital processor configured to receive a user's movement data relating to the user's physical activity during a physical exercise, the digital processor being configured to receive the user's pulse rate data, the digital processor being configured to determine the performance power of a physical exercise by the user by means of the movement data, wherein the performance power represents a function of the movement data, the digital processor being configured to determine the exertion level corresponding to the user's physical exercise by means of the user's pulse rate data, wherein the exertion level represents physiological information associated with the user, the digital processor being configured to estimate the user's performance by means of the performance power and the exertion level corresponding to the performance power by transforming exertion data representing the exertion level corresponding to the performance power to a specified exertion history point, wherein the performance characterizes the user's adaptation to the physical exercise.
