Associations between measures of physical fitness and cognitive performance in preschool children

Table 2 Single linear regression analyses using attention as dependent and a composite score of physical fitness as predictor variables

	Physical fitness (composite score)
	R²	ß-Coeff	r³	95% CI	p Value	Effect size
Attention (composite score)
Unadjusted model	0.183	0.43	0.43	0.172–0.609	0.001	F = 0.47
Adjusted model*	0.126**	0.40	0.34	0.091–0.630	0.010	F² = 0.14
Attention (sorting time in min)
Unadjusted model	0.102	− 0.32	− 0.32	− 1.376– − 0.166	0.013	F = 0.34
Adjusted model*	0.067**	− 0.36	− 0.31	− 1.604– − 0.131	0.102	F² = 0.07
Attention (correct cards, number)
Unadjusted model	0.094	0.31	0.31	0.490–5.014	0.018	F = 0.32
Adjusted model*	0.069**	0.21	0.19	− 0.808–4.668	0.098	F² = 0.07

Statistically significant (p < 0.05) relationships between physical fitness and attention are written in bold
