- The Cori Cycle. Before vigorous exercise (at rest) the level of blood lactate is at its normal level (about 25 mM). During a 400 m sprint, the value rises sharply in less than a few minutes to about 200 mM and then declines slowly to around 40 mM over 60 mins after the sprint. a. Discuss (or illustrate) the pathway and reactions that cause the rapid increase in lactate concentration during the sprint. b. What causes the slow decline in lactate concentration after the sprint? Why does the decrease occur more slowly than the rapid increase? c.
