The exercise intensity, at which the maximal fat oxidation (MFO) rate occurs, has been defined as Fatmax. It has been suggested that the fat oxidation rate during the Fatmax intensity is approximately 2-fold greater than at any other intensity although modifiable by several physiological conditions (training, previous exercise or meal). There are a few standardized protocols for estimating of Fatmax. The most common tests include: Cycle Ergometer (CE) and Treadmill (TM). Reviewing of tables of the study appoint that the extent of weight or fat loss in response to exercise training varies among individuals.
