RT Journal Article T1 Associations of Physical Fitness with Cognitive Performance in Children Aged 7–12 Years: A Cross-Sectional Study A1 Cortés-Rojas, Rafael A1 Castellano-Ruiz, María Isabel A1 Baeza-Medina, Alberto A1 Gil-Espinosa, Francisco Javier A1 Álvarez-Salvago, Francisco A1 Jiménez-García, José Daniel K1 Ejercicio físico - Aspectos psicológicos AB (1) Background: The objective of the present study was to analyze the association ofphysical fitness, specifically lower limb strength, abdominal strength, vertical jump, and grip strength,with cognitive performance, specifically focusing on selective attention and memory in childrenaged 7 to 12 years. (2) Methods: Two hundred twenty-seven students participated in this study.Pearson correlation was used to analyze potential relationships between the independent variablesand dependent variables. (3) Results: In relation to physical fitness, a higher number of abdominalrepetitions performed in 30 s showed a significant and positive association with a higher number ofcorrect responses assessed by the Stroop Test. Furthermore, at a functional level, higher grip strengthcorrelated with a greater number of correct responses and a higher average correct response time inthe Stroop Test. Additionally, grip strength showed a significant and positive correlation with thenumber of words recalled assessed by the word recall test. Our key findings showed a significantassociation of grip strength with the categories of cognitive status, selective attention, and memory.(4) Conclusions: This study reveals that physical fitness levels, especially grip strength and abdominalstrength, correlate with selective attention capacity in primary school students.
