Table 3. Summary of inter-relationships for kinematic variables in factor two.

Column 1 Variables increasing / decreasing together	Column 2 Variables increasing / decreasing together & opposite to those in column 1
Peak knee flexion	Ankle plantar flexion @ toe-off
Knee flexion @ heel-strike	Min ankle plantar flexion
* Hip abd / adduction ROM in follow - through	Max ankle plantar flexion
Hip abduction @ heel-strike	Time of peak thoracolumbar spine transverse rotation: thorax to L, pelvis to R
Hip abduction @ toe-off	Time of min ankle plantar flexion
	Ankle plantar flexion @ heel-strike & impact
	Time of peak hip internal transverse rotation

* Variables loading more strongly on other factors.
