For details of each group, see Table 1 

Recovery ratio RR =Ucrit2/Ucrit1

The subscripts 1 and 2 refer to the first and second swim tests and values in parentheses represent the averaged value for the first and second swim tests, since there was no significant difference between them

Significant differences (P<0.05) between groups within a column are denoted by superscript letters following each value
