All values are the group mean ± SE for 15 animals in each group. There was no significant difference between groups, P > 0.05 (ANOVA). However, there were significant differences within the vitamin group, P < 0.05 (repeated measures ANOVA). But there was no significant difference within sham and olive oil groups, P > 0.05 (repeated measures ANOVA).

P < 0.05 when compared with the other days (final three days).
