Abstract

Physiological assessment scale systems and methods are implemented using a variety of approaches. According to one implementation, a scale measures the physiological data of a user engaging sensor circuitry on a platform region of the scale. In a physiological assessment mode, physiological data of the user is detected at respective states of physical exertion. The physiological data is then processed by user-targeted circuitry to determine physiological parameters of the user pertaining to the respective physical exertion states, such as may pertain to an increase in exertion or a reduction in exertion. These physiological parameters may, for example, be used to provide an indication of the physical health and fitness of the user. Such parameters may then be associated with the user and saved to a data-access circuit, and also forwarded to a display which communicates the physiological parameters among other information to the user through the platform region.
