HUGHSON, R.L., M.E. TSCHAKOVSKY, and M.E. HOUSTON. Regulation of oxygen consumption at the onset of exercise. Exerc. Sport Sci. Rev., Vol. 29, No. 3, pp 129–133, 2001. Increased aerobic production of ATP at the onset of exercise could be limited by availability of metabolic substrates independent of O2, or interaction between O2 and metabolic substrates. We point out the importance of feedback control to match O2 supply to demand and discuss metabolic control at the onset of exercise.
