MFO: Maximal Fat Oxidation and Kinetics Calculation
Computes the maximal fat oxidation (MFO), the exercise intensity
that elicits it (Fatmax), the Fatmax zone and the crossover point from
indirect calorimetry data of a graded exercise test. Substrate oxidation is
estimated with the stoichiometric equations of Frayn (1983)
<doi:10.1152/jappl.1983.55.2.628>, Peronnet and Massicotte (1991, Can J
Sport Sci 16(1):23-29) or Jeukendrup and Wallis (2005)
<doi:10.1055/s-2004-830512>, and Fatmax is located with a third- or
second-degree polynomial, the measured values or the MRER method. Fat oxidation kinetics are described with the SIN model of
Cheneviere et al. (2009) <doi:10.1249/MSS.0b013e31819e2f91>, which returns
dilatation, symmetry and translation, together with the intensity at which
fat oxidation becomes negligible (Fatmin). Applications of these methods
are given in Achten et al. (2002) <doi:10.1097/00005768-200201000-00015>
and Montes de Oca et al. (2021) <doi:10.1080/17461391.2020.1788650>.
