RT: The retention time of each compound from GC-MS; VIP: Variable importance in the project; FC: Fold change. Mean ranks were calculated using the nonparametric Wilcoxon-Mann-Whitey test by SPSS 18.0, and FC was obtained by comparing those metabolites’ mean ranks between male and female rats in control, exhaustive exercise and recovery group. FC with a value >1 indicates a relatively higher level present in male rats as compared to the female rats, while a value <1 means a relatively lower level in male rats as compared to the female rats. S-d10: 10 days swimming group (exhaustive exercise group); R-d7: 7 days recovery group; p: Correlation coefficient from Mann-Whitney test. p<0.05 means the change is significant.
