"PURPOSE: Muscular power refers to the ability to perform high-intensity exercise for a fraction of a second to several minutes. Therefore, the purpose of this study was to develop age-and sex-specific normative reference values for lower-body muscular power assessed by the standing broad jump (SBJ) in Colombian schoolchildren. METHODS: A total of 7244 children and adolescents (55.7% girls, with a sample age range of 9-17.9 years) completed the SBJ test (median age, in years = 12.8 (SD 2.3); 25th-75th percentile: 11.0-15.0. The distance between takeoff and the heel of the closest foot at landing was recorded in centimeters, and participants were allowed one more try if they landed with their hands behind their feet. Smoothed percentile curves and tables for the 3rd, 10th, 25th, 50th, 75th, 90th and 97th percentiles were calculated using Cole’s LMS method. RESULTS: The one-way ANOVA tests showed that maximum SBJ (cm) was higher in boys than in girls (p<0.01). Post hoc analyses within sexes showed yearly increases in SBJ scores in all ages. In boys, the maximum SBJ scores 50th percentile ranged from 110 to 165 cm. In girls, the 50th percentile ranged from SBJ scores was 96 to 120. Both linear and quadratic age terms were statistically significant predictors of SBJ trends across age. CONCLUSIONS: Our results provide reference standards for sex- and age-specific SBJ scores in Colombian schoolchildren aged 9-17.9 years for the first time. The proposed reference values can be used to interpret SBJ scores in Colombian schoolchildren."
