[Utilization and restitution of energy sources during muscular activity under steady-state metabolic conditions].
During muscular activity at steady state of metabolism both the carbohydrate and the free fatty acids are utilized as energy sources. Kreatine phosphate expense, carbohydrate mobilization, and intensity of glycolysis during the same work are in positive correlation with the work intensity, while fatty acids mobilization is in negative correlation. Intensity of restoration of energy sources is in positive correlation with the intensity of work and the energy source expense, while being in negative correlation with steady state level of metabolism. In trained organism, both the steady state level of metabolism during muscular activity and intensity of restitution during recovery period are greater than in untrained organism.
