Table 1.  Details of the field tests performed by the two experimental groups.

Tests

Group A

30-15 IFT

Original test (intermittent incremental shuttle (40-m) run test)

30-15IFT-CONT

Similar to the 30-15IFT but with no rest periods, i.e., performed continuously (continuous incremental shuttle (40-m) run test)

30-15IFT-LINE

Similar to the 30-15IFT but without COD, i.e., performed on a 400-m track (intermittent incremental straight-line test)

Group B

30-15 IFT

Original test (intermittent, incremental shuttle (40-m) run test)

30-15IFT-28m

Similar to the 30-15IFT but with more COD, i.e., performed on a shorter shuttle-length (intermittent incremental shuttle (28-m) run test)
