(JP10225531-A)      The system has an input unit which inputs physiological information relating to the user. A calculation unit calculates atleast two movement strength levels of the user based on the input physiological information. The effect of specific movement is obtain in the zone of the movement strength level. Each zone is calculated as a range of value corresponding to physiological characteristics of the user.    The starting and ending point of the zone range corresponds to specific physiological value. A sensor is provided to detect physiological characteristics while user is under exercising state. The level of a first scale (20) of atleast two levels of possible movement strength of the user corresponds to the calculated zone. The first scale includes a mark which shows the effect of each zone. A display unit (18) displays the zone during practice of user.    USE -   For respiratory system, blood circulating system improvement.    ADVANTAGE -   Enables user to maintain desired movement strength level.    (JP3131396-B2)      The system has an input unit for inputting relevant physiological information about a user. The calculator calculates appropriate exercise intensity levels for the particular user based on the input information. A sensor detects the physiological condition of the user during exercise. The calculator uses the physiological condition of the user to determine particular zone within which user is currently performing.    A display unit displays the user's exercise intensity based on the detected physiological condition during exercising. The display unit includes a scale of levels of possible exercise intensities. The scale is composed of major subdivisions corresponding to the zones calculated by the calculator and includes indicia indicating the benefits of each zone.    USE -   For a person training for a marathon.    ADVANTAGE -   Enables user to understand their current exercise intensity and adjust and maintain their exertion level to a desired level.
