DME: Dynamic muscular endurance; 4-CRT: 4-choice reaction time; ConRT: Reaction time for the congruent task; InconRT: Reaction time for the incongruent task; PA: Physical activity; SES: Socioeconomic status; SRT: Simple reaction time; ∆ Simon: Simon incongruent RT minus congruent RT; SMS: Static muscular strength. Natural logarithm data of agility, speed, SRT,4-CRT, ConRT, InconRT, and ∆ Simon were used in the analysis. * significant at <0.05; ** significant at <0.01.
