An apparatus and method are disclosed for capturing multiple physiological parameters and indicating the sensation of fatigue during physical activities. The apparatus for capturing physiological data comprises: one or more sensors for sensing one or more corresponding physiological parameters associated with the variation of one or more organs in the human body; push button and indicator lamp system for indicating the sensation of fatigue; and a microcontroller to receive and process the sensed variations of one or more physiological parameters. these individual subsystems are combined together to operate as a single system when data gathering during exercise stress tests.
