When evaluating the evidence relating to the importance of physical factors for CODS, a
major difficulty is the huge variety of CODS tests used to assess this quality. This is expected
because different invasion sports require a range of movement patterns and footwork. For
example, some sports involve lateral shuffling such as basketball, while other sports such as
rugby union or league commonly require side-stepping or cutting movements. One element
that is common to all of these tests is that the athlete is required to complete a pre-planned
course defined by obstacles such as cones in the shortest possible time, usually assessed with
an electronic timing system.
