Values are means ± SD. LoA, limits of agreement; CV, coefficient of variation; SIN, sine model; MV, measured values; P3, 3^rd polynomial curve; Fat_max, exercise intensity at which maximal fat oxidation rate occurs; MFO, maximal fat oxidation rate; RER Fat_max, respiratory exchange ratio at Fat_max; % HR_max Fat_max, % maximal heart rate at Fat_max; % Fat_max, % maximal aerobic power output at Fat_max.

*P<0.05 between SIN and the other approaches (P3 and MV).
