Figure 5.

Effect of a five-week CRV supplementation on the serum blood urea nitrogen (BUN) concentration (A) and creatine kinase (CK) activity (B) after acute exercise challenge. The indicated four groups underwent 90 min of swimming exercise, and blood was sampled after 60 min of rest. Data are expressed as means ± standard errors of the mean for n = 10 mice per group. Columns with distinct superscript letters (a and b) differ significantly at p < 0.05. Values above the columns are the relative percentage (%) of the vehicle group.
