Table 2. Summary of inter-relationships for kinematic variables in factor one.

Column 1 Variables increasing / decreasing together	Column 2 Variables increasing / decreasing together & opposite to those in column 1
Peak hip external transverse rotation	Hip internal rotation @ impact
Peak hip abduction	Hip peak internal rotation
Hip transverse rotation ROM during follow-through
Hip abduction @ impact
Thoracolumbar spine transverse rotation ROM during follow-through
Thoracolumbar spine flexion/extension ROM during follow-through
Hip external transverse rotation @ heel-strike
Thoracolumbar spine abd/adduction ROM during follow-through
Hip external transverse rotation at toe-off
Hip flexion / extension ROM during follow-through
Hip extension @ toe-off
* Thoracolumbar spine transverse rotation (thorax to R, pelvis to L) @ impact
* Hip abd / adduction ROM during follow-through
* Knee flexion @ impact

* Variables loading more strongly on other factors.
