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

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

  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
