Abstract: The embodiments of the disclosure provide a method for evaluating a health condition indicator of a subject, a host, and a computer readable storage medium. The method includes: obtaining a reference heart rate of the subject and determining a heart rate indicator of the subject according to the reference heart rate; determining a fitness indicator of the subject based on physiological information of the subject; determining an age indicator of the subject based on an age of the subject; and determining the health condition indicator of the subject at least based on the heart rate indicator, the fitness indicator, and the age indicator.

Abstract: The present invention discloses a method for determining a degree of response to a physical activity. Acquire a physical activity signal measured by a sensing unit in the physical activity. Determine first data of a first physical activity feature set based on the physical activity signal. Determine a recognition of the degree of response to the physical activity based on the first data of the first physical activity feature set by a mathematical model describing a relationship between the first physical activity feature set and the degree of response to a physical activity. A portion of a first mechanism of the mathematical model adopts at least one portion of a second mechanism of a first neural network model associated with the second physical activity feature set.

Abstract: The present invention discloses a method for determining psychological stress. The method includes the steps of: acquiring physiological parameter data comprising a first physiological parameter and a second physiological parameter temporally corresponding to the first physiological parameter; determining a reliability in an estimation of the psychological stress of the physiological parameter data based on a degree of match between the physiological parameter data and a plurality of criteria, wherein the plurality of criteria are determined based on a first reference value of the first physiological parameter and a second reference value of the second physiological parameter; and determining an indicator of the psychological stress based on the physiological parameter data and the reliability in the estimation of the psychological stress of the physiological parameter data.
