Current physical status evaluation subsystem using user-specific tuned membership functions in sport activity risk calculation

In this paper a subsystem of a fuzzy logic-based sport activity risk level calculation model is presented. This subsystem evaluates the risk from the patient's measured physiological parameters as heart rate, systolic and diastolic blood pressure in real-time. For the most reliable results the input membership functions are tuned according to the influential parameters on the measured factors before the real time calculation offline. The obtained membership functions are user-specific thus the result of the evaluation is more reliable.
