For details of each group, see Table 1 

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

O2max was taken concurrently with the Ucrit shown inTable 3 

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