Abstract

Objective: present updated evidence on the physiological process of mobilization, transport and oxidation of fatty acids, mechanisms associated with the intensity of physical exercise for weight loss. Methods: a search was made in PubMed, Cochrane, Scielo, LILACS, ScienceDirect with the words obesity, lipolysis and physical exercise. Results: constant physical exercise with variations in training intensities, physiological responses that can allow the stimulus delivered, facilitating the energy metabolism of fatty acids. Conclusions: the physiological changes generated by physical exercise with intensity changes within the same session, the beneficial effects to maintain weight loss in the long term.
