1. A method of assessing a physiological condition of a subject, the method comprising:

  • collecting data over a period of time by a wearable sensor module attached to the subject, wherein the sensor module comprises at least one physiological sensor for measuring the following physiological parameters;

    body temperature, heart rate, and sweat rate, and wherein the sensor module comprises at least one physical activity sensor for measuring the physical activity of the subject;

    analyzing data to identify at least one time-dependent change in at least one of the physiological parameters during at least one less-active period and during at least one more-active period for the subject comprising determining whether at least one of the physiological parameters exhibits a time-dependent change that precedes or lags with respect to at least one other the physiological parameters; and

    making an assessment of a physiological condition of the subject via at least one algorithm factoring the at least one time-dependent change in context of the physical activity of the subject, wherein the assessment comprises one or more of the following;

    VO2, VO2max, thermoregulatory functioning, metabolic information, active calories burned, total calories burned, hydration status, heart rate variability, cardiac response, stress level, warm up time, recovery time, activity performance level;

    wherein the analyzing data and making an assessment steps are performed by at least one processor.
