Lactic acid production in submaximal work

  • 80 Accesses

  • 1 Citations

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.
