Here’s another spreadsheet. Mader’s basic model Its a very crude implementation the model from the 1986 paper. The sheet may have errors and I don’t have a bio/physio background, so consider this a simple numerical calculator, of sorts. The main references are in the sheet. Hauser, 2014 and Mader, 1986. I coded the sheet in **LibreOffice Calc** – it’s free and useful. There are some modifications you can make to have this in Excel (charting, VBA coding). _Input parameters_ Not sure where _vol. rel._ comes from - if you look at Incsyd reports, Vol. rel. seems to be based on a calc using body characteristics (height, weight, body fat, etc.) Seems _K”s_ is adjusted based on VLaMax magnitude, high = 1.728, low = 1.331 Where to get VO2Max? – Watch estimate, ASCM formula, 5m Cycling power correlations, Software (WKO5, GC), other correlations (ramp test, Cooper test, etc.) Where to get CP? – intervals, WKO5, GC, maybe TR (what model?). Use FTP also. Need good proxy for mlss. How to estimate VLaMax? – Back-calculate. Use spreadsheet to iterate by varying VLaMax to find CP/FTP (mlss) Fat and CHO correlations – I have no idea where they come from.
