Table 1. Summary of the results of Effect Size (ES) analyses for selected angular kinematic data at the end of the backswing and at ball release. Data were summarized so that only comparisons that recorded Large or Very Large (Hopkins 2002) ES are listed, with those that recorded Trivial, Small or Medium ES left blank.

Variable	Comparison by Thrower			Comparison by Length
Variable	T1-T2	T1-T3	T2-T3	Front-Middle	Front-Back	Middle-Back
At the end of the backswing
Pelvic rotation angle					L
Trunk flexion angle		VL
Upper trunk rotation		VL		VL	VL	L
Shoulder flexion angle	VL	VL		-L	-VL	-L
Shoulder abduction angle	VL	VL	-L
Elbow flexion angle	-VL	-VL	VL	-L	-VL	-L
At ball release
Pelvic rotation angle	-L	-VL	-L
Trunk flexion angle		VL	VL
Upper trunk rotation		VL	VL

L = Large VL = Very Large.
^* Negative values indicate that the first group is smaller than the second (e.g. the values for T2 are small than for T3)
