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)
