The purpose of the present study was to generate normative values for standing long jump test (SLJ) in 9- to 17.9-year-olds and to investigate sex and age group differences. The sample was comprised of 8,034 healthy Colombian schoolchildren [boys n=3,488 and girls n=4,546; mean (standard deviation) age 12.8 (±2.3) years old]. Each participant performed two SLJ. Centile smoothed curves, percentile, and tables for the 3rd, 10th, 25th, 50th, 75th, 90th, and 97th percentiles were calculated using Cole’s LMS method. The two-way ANOVA tests and Cohen’ d showed that the maximum SLJ (cm) was higher in boys than in girls across age groups (p<0.01), reach the peak at 13 years. Post hoc analyses within the sexes showed yearly increases in SLJ in all ages. In boys, the 50th percentile SLJ score ranged from 109 to 165 cm. In girls, the 50th percentile jump ranged from 96 cm to 120 cm. For girls, jump scores increased yearly from 9 to 12.9 years of age before reaching a plateau at an age between 13 to 15.9. Our results provide, for the first time, sex- and age-specific SLJ reference values for Colombian schoolchildren aged 9 - 17.9 years. The normative values presented in this study provide the basis for the determination of the proposed age- and sex-specific standards for the FUPRECOL Study-Physical fitness battery for children and adolescents.
