In this paper, we tried to define the psychological state by quantitatively evaluating the anxiety data from humans in an anxiety state. It has been reported that the electric signals of human can be correlated with their emotional state. We chose heart rate, respiration state, temperature and skin conductance as the anxiety parameters. For experiment protocole, the subject was given exercising load to induce the anxiety state and the exercise was done using the FITRON Cycle Ergometer. We divided the data into three stages : rest period, exercise period, and recovery period. During evaluation, we counted the heart rate, slope of heart rate, and the skin conductance.
