Human centered training: perceived exertion as main parameter for training adaption

Regular physical activity is important for a healthy lifestyle. The physical activity should be performed with the right individual intensity. Today it is common to use the heart rate as indicator for the optimal individual training intensity, but the subjective intensity of the trainee is not considered. In this paper we present an approach which focuses on the perceived exertion of the trainee and helps to reach and keep a user-defined intensity level.
