Principal Components differences in Low Dive kinematics.

Kinematic Variable	Explained Variability (%)	PC Score PS	PC Score nPS	p-Value	Effect Size	Feature Explanation
Lower Limb, Ipsilateral
Hip abd-adduction	17.2	10.2 ± 31.0	−11.2 ± 43.3	0.003	0.57	Greater abduction with less ROM
Lower Limb, Contralateral
Hip abd-adduction	58.6	−22.3 ± 71.3	24.4 ± 90.1	0.003	0.58	Lower abduction (all movement)
Upper Limb, Contralateral
Shoulder intra-extra rotation	21.3	−23.6 ± 96.4	25.8 ± 141.1	0.034	0.41	Greater internal rotation at take-off and ball contact
Wrist flexion-extension	11.9	10.6 ± 45.7	−11.6 ± 53.8	0.022	0.45	Less extension during initiation and take-off
Pelvis/Trunk/Head
Pelvis ipsilateral rotation	14.1	−3.6 ± 14.3	4.0 ± 18.4	0.018	0.46	Less ipsilateral rotation (all movement)
Trunk ipsilateral rotation	14.0	−8.6 ± 30.3	9.4 ± 42.9	0.012	0.49	Less ipsilateral rotation (all movement)

Note: PS = preferred side, nPS = non-preferred side; n.s. = not significant.
