Fig. 2. Effects of sustained exercise, fatigue, and subsequent recovery, on rates
of O2 uptake
(
O2; mean
± S.E.M.); arterial blood pH (pHa),
PO2 (PaO2) and
total O2 content (CaO2); red muscle
PO2
(PRMO2), and the arterial to red
muscle PO2 gradient
(PaO2PRMO2).
Data are provided for rainbow trout swimming at two sustained speeds in body
lengths s1 (BL s1); at their maximum
sustained swimming speed (Max); immediately upon fatigue (note that
O2 data are not
available for this instance), and at 1 h and 2 h of recovery (Rec). NA, data
not available. N=5 in all cases, for those variables where exercise
elicited statistically significant effects by one-way ANOVA for repeated
variables, a common superscript indicates no significant difference between
means by Bonferroni post-hoc test (P<0.05).
