Table 2 Repeated measures ANOVA for each outcome and mean differences from pairwise comparisons (n = 123)

Outcome	Effects	F	P	η_p ²	Mean difference^a
Fx 0°	State	0.001	0.982	4.0 × 10⁻⁶	NS
	State + elastomer	0.033	0.856	2.7 × 10⁻⁴	NS
	Elastomer	2904.2	<0.001*	0.96	0.74 N
Fx 5°	State	23.6	<0.001*	0.16	0.21 N
	State + elastomer	11.3	0.001*	0.09	0.30 N
	Elastomer	4281.9	<0.001*	0.97	2.74 N
My 0°	State	2.3	0.134	0.02	NS
	State + elastomer	0.2	0.685	0.001	NS
	Elastomer	4.0	0.047*	0.03	−0.05 Nmm
My 5°	State	3.9	0.050*	0.03	0.33 Nmm
	State + elastomer	3.7	0.056	0.03	NS
	Elastomer	282.3	<0.001*	0.70	3.12 Nmm

Degrees of freedom (1, 121) for each effect
F F statistic, η _p ² partial eta squared, NS not significant
*P ≤ 0.05 was significant
^aIf P is significant, mean differences recorded from pairwise comparisons for state (dry–wet), elastomer (yes–no), and interaction of state + elastomer
