Abstract

A method is provided for correcting reference parameters based on weight variations of a subject. The parameters that can be corrected may be metabolic rate, metabolic equivalent (MET), dehydration rate, drug dosage, exercise intensity, calorie usage, work level, and oxygen consumption. A corrected parameter for a subject can be determined by the factor $P_r\frac{{\left({\mathrm{wt}}_s\right)}^x}{y}$
to obtain a corrected parameter (P_s). In the factor, wt_s is the weight of the subject, x is preferably ⅓, P_r is the reference parameter to be corrected, and y is preferably (wt_r)^z, wherein wt_r is the reference weight and z is preferably ⅓.

Claims

1. A method for correcting a parameter for weight variation comprising the steps of:

selecting one of a subject parameter (P_s) and a reference parameter (P_r),

adjusting the other parameter in accordance with the formula

$\begin{array}{cc}\frac{P_s}{P_r}=\frac{{\left({\mathrm{wt}}_s\right)}^x}{y}& \left(1\right)\end{array}$

wherein wt_s is the weight of the subject corresponding to P_s and x ranges from 0.25 to 0.37, and wherein y=(wt_r)^z, wherein wt_r is the weight of the reference person corresponding to P_r and z ranges from 0.25 to 0.37.

2. The method of claim 1, wherein y is in the range of 3.0 to 5.8.

3. The method of claim 1, wherein

$\frac{\left({\mathrm{wt}}_s\right)}{y}$

 

⁢

is ⁢

 

⁢

( wt S ) 0.25 + ( % ⁢

HRR * ⁢

0.12 ) y ,

wherein % HRR is the heart rate reserve as a percent of maximum heart rate for the subject.

4. The method of claim 1, wherein the initial parameter is a metabolism dependent parameter which is selected from the group consisting of metabolic rate, metabolic equivalent (MET), dehydration rate, drug dosage, exercise intensity, calorie usage, and work level.

5. The method of claim 1, wherein the initial parameter is oxygen consumption.

6. The method of claim 1, wherein the factor is

$\frac{{\left({\mathrm{wt}}_s\right)}^{1/3}}{4.22}.$
