Abstract
Objective: The aim of this study was to determine the relationship between the components of physical fitness (PF), creativity and fluid intelligence, as well as to determine which components of PF are predictors of the analysed cognitive potential. Material and Methods: A total of 584 Spanish schoolchildren (6-11 years old; age = 8.62 ± 1.77 years) took part in this study. Creativity was assessed using the Torrance Tests of Creative Thinking (TTCT) and fluid intelligence through TEA-1. Moreover, PF components were evaluated using a 25 m sprint, handgrip strength, standing long jump and 20 m SRT. Results: Boys exhibited a better PF performance than girls (p range from = < 0.001 to 0.05), as well as higher creativity score (p < 0.001), the fluid intelligence score and QI score (p < 0.05, respectively). Moreover, PF components (CRF, strength and speed) were positively associated with creativity (p range from = < 0.001 to 0.001) and fluid intelligence (p range from = < 0.001 to 0.015). Regression analysis showed that the creativity model explained between 31.4% and 36.6% of the variance (R(2) = 0.314-0.366, p < 0.001), while the fluid intelligence model accounted for 25.5% to 33.1% of the variance (R(2) = 0.255-0.331, p < 0.001 to 0.001). Conclusions: A positive relationship was found between creativity, fluid intelligence, and PF components. Children with higher PF levels scored better in creativity, with notable differences between boys and girls. These findings highlight the educational value of incorporating structured physical activity into school settings to support both cognitive and physical development.
