a = taken from Costigan et al. (2002).b = calculated from Hewett et al. (2005).c = taken from Sigward and Powers (2007). STR = straight golf set-up foot position. EXT = externally rotated golf set-up foot position.† = Statistical difference between the STR & EXT foot rotation conditions at p < 0.05.
