Assessing Inter-Effort Recovery and Change of Direction Ability with the 30-15 Intermittent Fitness Test

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)
	30-15_IFT-CONT	Similar to the 30-15_IFT but with no rest periods, i.e., performed continuously (continuous incremental shuttle (40-m) run test)
	30-15_IFT-LINE	Similar to the 30-15_IFT 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)
Group B	30-15_IFT-28m	Similar to the 30-15_IFT but with more COD, i.e., performed on a shorter shuttle-length (intermittent incremental shuttle (28-m) run test)
