Regulation of glucose and fatty acid metabolism in skeletal muscle during contraction. Zoppi IV ; Sandro M. Hirabara V ; Kaio F. Leandro VI ; Fe R. Barbosa I ; Igor H. Sampaio II ; Iracema H. The glucose-fatty acid cycle explains the preference for fatty acid during moderate and long duration physical exercise. In contrast, there is a high glucose availability and oxidation rate in response to intense physical exercise.

ROS reduces the glicollse of the Krebs cycle, and increases the activity of mitochondrial uncoupling proteins. The opposite effects happen during moderate physical activity.

Thus, some issues is highlighted in the present review: Why does skeletal muscle prefer lipids in the basal and during moderate physical activity? Why does glucose-fatty acid fail to carry out their effects during intense physical exercise? How skeletal muscles regulate the lipids and carbohydrate metabolism during the contraction-relaxation cycle? Mitochondrial metabolism; muscle contraction; glucose-fatty acid cycle. Em contraste, sob elevada disponibilidade de carboidratos, utilizam predominantemente glicose.

Os carboidratos constituem uma valiosa fonte de energia ao nosso organismo. Esse conceito foi proposto originalmente por Randle e cols.
