Claim One:
1. A method for analyzing the biological age of a subject comprising: obtaining age, body fat percentage, weight and sex information from a subject; measuring the subject's average oxygen consumption when the subject is at rest; measuring the subject's average respiratory exchange ratio when the subject is at rest; measuring the subject's average oxygen consumption when the subject's respiratory exchange rate is about 0.85; measuring the subject's average oxygen consumption when the subject's respiratory exchange rate is about 1.00; measuring the subject's average work produced when the subject's respiratory exchange ratio is about 1.00; and calculating the subject's biological age as a function of the subject's average oxygen consumption at rest, the subject's average respiratory exchange ratio when the subject is at rest, the subject's average oxygen consumption when the subject's respiratory exchange rate is about 0.85, the subject's average oxygen consumption when the subject's respiratory exchange rate is about 1.00, and the subject's average work produced when the subject's respiratory exchange ratio is about 1.00; wherein the calculation is dependent on the sex of the subject.
