How does the Biomet calculate the basal metabolic rate (BMR) of a person?

Postby zax1111 » Sun Dec 25, 2016 1:14 pm

Hello! Merry Christmas, everyone!

1. I have just bought a license of Biomet professional. When calculating PET, the basal metabolic rate will be calculated according to the input human data including age, gender, weight, height. Does anyone know how it is calculated behind? Is there a formula? I have run through the website and forum, and found nothing.

2. Beside, if i want to calculate someone is running, can I just change the walking speed to a higher value (2.5m/s) and calculate the sum of them for using? What is the equation used here?

Thank you in advance if you can give me an illustration or a link.

Kind regards,
Anxiao

Dear Tim,

I also want to ask about the standard human model in Biomet.
I notice that the person metabolism,using met as unit, is not equal to that in ISO7730.
For instance, walking with a speed of 1.1m/s(4km/h) corresponds 1.4 met in BIOmet, which is quite lower than that in ISO7730(2.8met).
It confuses me.

Hi,

have you checked out http://www.envi-met.info/doku.php?id=apps:biomet_pmv ?

There the details are documented.
1.4 met for walking on flat ground sounds too high for me.
The values used in ENVI-met are based on regressions of the standard values.
It is important so see if the values are based per m2 or for the complete body, so divided by Adu body surface or not.

Best
Michael
