    Notes: Summary From the amount of work at steady state, and the concentration of split phosphagen, equivalent to the oxygen debt, measured on an exercising isolated dog gastrocnemius, the velocity constant of phosphagen (ATP+CP) resynthesis, assuming that this reaction is an exponential one, could be calculated and found to be 1.98 min−1, the same value as found in man in exercise. The mechanical equivalent of phosphagen splitting in man has been calculated as 4.3 kcal/mol.

    Relationship between O2 consumption, high energy phosphates and the kinetics of the O2 debt in exercise (1968)

    Notes: Summary The oxygen consumption together with lactic acid production and concentration of ATP, ADP, and creatinephosphate was measured during exercise and recovery on an isolated dog gastrocnemius. Oxygen debt contraction and payment follow an exponential path with a half reaction time of about 20 sec. The concentration of ATP and ADP at steady state seem to be unaffected by the intensity of the exercise when this is submaximal and no appreciable production of lactic acid takes place. The concentration of creatinephosphate in muscle at steady state decreases with the intensity of the exercise. The ratio of the oxygen consumption at steady state to the alactic oxygen debt is identified with the speed constant of the resynthesis of phosphagen in muscle; the half reaction time of this process is 17–20 sec. The total alactic oxygen debt amounts to about 50 ml/kg of muscle. These figures are in good agreement with earlier data found in man.

    Lactic acid production in submaximal work (1967)
    Springer
    European journal of applied physiology 24 (1967), S. 57-61 
    Details
    ISSN: 1439-6327

    Topics: Medicine
    Notes: Summary In subjects performing a submaximal exercise, involving from 70% to about 100% of the maximum O2 consumption, lactic acid (L.A.) is produced only at the onset of the exercise, during the O2 debt contraction phase; no L.A. production occurs in the later part, when a steady state of O2 consumption is reached. That no L.A. production takes place in submaximal exercise at steady state is thus confirmed. The L.A. increase in concentration in submaximal exercise can be interpreted as indicative of the hypoxic condition of the active muscles at the onset of the exercise.
