1. A method of measuring physiological adaptability of a subject, the method comprising:

  • receiving, from a first sensor, a first data signal indicating a first biological function of the subject;

    receiving, from a second sensor, a second data signal indicating a second biological function of the subject;

    calculating a stress adaptability of the subject based on the first data signal and the second data signal, comprising;

    determining, based on the first data signal from the first sensor and the second data signal from the second sensor, a single first average heart rate corresponding to time intervals when the subject is generally inhaling;

    determining, based on the first data signal from the first sensor and the second data signal from the second sensor, a single second average heart rate corresponding to time intervals when the subject is generally exhaling; and

    calculating the stress adaptability based on a difference between the single first average heart rate and the single second average heart rate; and

    reporting the calculated stress adaptability,wherein the first biological function includes a respiratory function, the second biological function includes a cardiac function;

    wherein the method further comprises detecting a sequence of heart beats in the second data signal, each sequential pair of detected heart beats in the detected sequence of heart beats defining a start time and an end time of an associated time interval; and

    wherein the calculating the stress adaptability of the subject based on the first data signal and the second data signal further comprises determining time intervals of the sequential pairs of detected heart beats when the subject is generally inhaling and time intervals of the sequential pairs of detected heart beats when the subject is generally exhaling.
