Fig. 3. (A) Arterial PCO2, (B) blood pH and (C)
plasma bicarbonate concentration in trained and untrained turtles swum from 0
to 2 h during recovery from anoxic submergence. There was no significant
interaction between time and treatment for any of the parameters. Values are
mean ± S.E.M. (N=69).
The pooled means of the 2 h active recovery/trained treatment were
significantly higher than those from the other treatments for arterial
PCO2 and blood pH. Differing letters indicate
significant differences between time points for pooled means (two-way
RM-MANOVA, Student's t-test, P<0.05). PR, passive
recovery; AR, active recovery; U, untrained; T, trained. 1 torr=133.3 Pa.
