    PURPOSE: There is increasing evidence that cardiorespiratory fitness (CRF) is an important health marker in youth. CRF values for children and adolescents from different countries have been published, but there is a scarcity of reference values for Latin American children and adolescents using recommended CRF estimation field tests such as the 20-m shuttle-run test as evidence of CRF in Colombian schoolchildren. In addition to presenting normative reference values, we also aim to establish the proportion of subjects whose aerobic capacity is indicative of future cardiovascular risk. METHODS: A total of 7244 children and adolescents (55.7% girls, with a sample age range of 9-17.9 years) completed the 20 m shuttle-run test (median age, in years = 12.8 (SD 2.3); 25th-75th percentile: 11.0-15.0. We expressed performance as the number of shuttle-runs completed and the estimated peak oxygen consumption (VO2peak). Smoothed percentile curves and tables for the 3rd, 10th, 25th, 50th, 75th, 90th and 97th percentiles were calculated using Cole’s LMS method. In addition, we calculated the number of participants who fell below proposed cut-offs for low CRF based on either completed shuttle-runs or by VO2peak. RESULTS: In general CRF levels increased with age. Among boys CRF, where higher between the ages of 14 and 17 and in girls between the ages of 12 and 14, but this increase was more modest. Shuttles and VO2peak were higher in boys than in girls in all age-specific groups. The proportion of subjects with a CRF indicative of future cardiovascular risk was 11.5%. By sex, 9.65% of boys and 13.1% of girls (X2 p < .001) displayed an unhealthy aerobic capacity in this study. CONCLUSIONS: Our results provide reference standards for sex- and age-specific twenty- meter shuttle-run test scores and VO2peak values in Colombian schoolchildren aged 9-17.9 years for the first time. These values are particularly important in public health and educational settings, and future research should establish a cut-off value for test performance that can predict present or future ill health.

    Reference values for standing broad jump in colombian schoolchildren the fuprecol study: 2767 board #290 June 3, 930 AM - 1100 AM

    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.

    Test-retest reliability of a field-based physical fitness assessment for children and adolescents aged 9-17 years: the fuprecol study 360 Board #197 June 1, 1100 AM - 12:30 PM

    PURPOSE: Substantial evidence indicates that youth physical fitness levels are an important marker of lifestyle and cardio-metabolic health profiles and predict future risk of chronic diseases. The reliability physical fitness tests have not been explored in Latino-American youth population. The present study aims to determine the test-retest reliability of the Fitness Test Battery in children and adolescents aged 9-17 years. METHODS: Participants were 229 Colombian youth (boys n=124 and girls n=105) aged 9 to 17.9 years old. Five components of field-based physical fitness were measured: 1) morphological component: height, weight, body mass index (BMI), waist circumference, triceps skinfold, subscapular skinfold, and body fat (%) via impedance; 2) musculoskeletal component: handgrip and standing long jump test; 3) motor component: speed/agility test (4x10 m shuttle run); 4) flexibility component (hamstring and lumbar extensibility, sit-and-reach test); 5) cardiorespiratory component: 20-meter shuttle-run test (SRT) to estimate maximal oxygen consumption. The tests were performed two times, 1 week apart on the same day of the week, except for the SRT which was performed only once. Intra-observer technical errors of measurement (TEMs) and inter-rater (reliability) were assessed in the morphological component. RESULTS: Reliability for the Musculoskeletal, motor and cardiorespiratory fitness components was examined using Bland-Altman tests. For the morphological component, TEMs were small and reliability was greater than 95% of all cases. For the musculoskeletal, motor, flexibility and cardiorespiratory components, we found adequate reliability patterns in terms of systematic errors (bias) and random error (95% limits of agreement). When the fitness assessments were performed twice, the systematic error was nearly 0 for all tests, except for the sit and reach (mean difference: ?1.03 % [95% CI= ?4.35 % to ?2.28 %]. CONCLUSIONS: The results from this study indicate that the “Fuprecol study” field-based physical fitness administered by physical education teachers, was reliable for measuring health-related components of fitness in children and adolescents aged 9-17.9 years old in a school setting in Colombia.
