q2 i? After additional adjustment for BMI and cardiorespiratory fitness (or speed-agility), significant associations between fitness components and academic achievement attenuated and disappeared except for 1-RM leg press. → Cadenas-Sanchez 2020

Cadenas-Sanchez, C., Migueles, J. H., Esteban-Cornejo, I., Mora-Gonzalez, J., Henriksson, P., Rodriguez-Ayllon, M., Molina-García, P., Löf, M., Labayen, I., Hillman, C. H., Catena, A., & Ortega, F.

q2 · i? · associational · r2

Cross-sectional regression (Model 2) in 106 children with overweight/obesity. Results "were attenuated, and significant associations disappeared except for those in the lower-limbs muscular strength (1-RM leg press)". No multicollinearity was observed (variance inflation factors < 3).

"After additional adjustment of BMI and cardiorespiratory fitness or speed-agility (Model 2), the results observed for the field and laboratory tests were attenuated, and significant associations disappeared except for those in the lower-limbs muscular strength (1-RM leg press)"
