Several studies have shown that low cardiorespiratory fitness (CRF) is a significant independent risk factor for future cardiometabolic disease in adult life. The aim of this study was to examine the relationship between CRF and health status in children and adolescents in Bogota, Colombia.A cross-sectional study was conducted in 921 children and adolescents aged 9-17 years living in the metropolitan area of the District of Bogota, Colombia (2,480m asl). CRF was assessed with the 20m shuttle run test (Course-Navette) according to ALPHA-FITNESS and FITNESSGRAM standards. Blood pressure, waist circumference, hip circumference, body composition (body fat percentage, fat body mass, and fat-free mass by bioimpedance), skin fold calipers, body mass index, and sexual maturity (Tanner) were used as indicators of physical health.After adjusting for sex, age, and sexual maturity, significant inverse relationships were seen between CRF and body mass index (r=-0.107), body fat percentage (r=-0.197), fat body mass (r=-0.159), skin fold (r=-0.246), and waist circumference (r=-0.169); P

epidemiological and experimental evidence suggest the role of muscular strength has been increasingly recognized in the prevention of chronic disease in early life, and features of the cardiometabolic disease have also been negatively associated with muscle strength in adulthood. The aim of this study was to examine whether the association between muscular fitness and physical health status among children and adolescents from Bogotá, Colombia.cross-sectional study in 921 schoolchildren aged 8-11 years from Bogotá, Colombia. A muscular fitness score (MFS) was measured using handgrip strength and standing long jump and vertical jump. Each of these variables was standardized as follows: standardized value = (value = mean)/SD. The muscle fitness score was calculated as the mean of the three standardized scores. MFS was recoded into quartiles Q1 (low fitness) to Q4 (high fitness). The body mass index (BMI), skinfold thickness, waist and hip circumference, body composition by bioimpedance (BIA), blood pressure and self-declaration sexual maturation were measured such as indicators associated with future cardiovascular events.the average age was 13.0 ± 2.6 years. Participants with Q4 (high fitness), show a better physical health status (BMI, blood pressure, body fat and waist circumference (BMI, blood pressure, body fat and waist circumference, p[linear X2] = 0.01). Individuals with Q1 and Q3 (low fitness) had 4.06 times (95%CI 2.60 to 6.34; p = 0.043) risk of excess body fat and 1.57 times (95%CI 1.02 -1.89; p = 0.020) risk of abdominal obesity.our results show that muscle fitness is associated with better physical health status. The testing of muscle strength at early ages should be included in health- monitoring systems.Objetivo: la evidencia epidemiológica y experimental sugieren que la disminución de la fuerza muscular en las etapas tempranas de la vida se asocia de manera independiente con la presencia de factores de riesgo asociados a enfermedad cardiometabólica en la edad adulta. El objetivo de este estudio fue examinar la asociación entre el desempeño muscular y el bienestar físico de niños y adolescentes de Bogotá, Colombia. Métodos: estudio transversal, realizado en 921 niños y adolescentes de entre 9 y 17 años de Bogotá, Colombia. Se calculó el Índice General de Fuerza (IGF) como marcador del desempeño muscular con las pruebas de salto longitud sin impulso, salto vertical y dinamometría manual. El IGF se recodificó en cuartiles, siendo el cuartil (Q4) la posición con mejor valor del desempeño muscular. El índice de masa corporal (IMC), los pliegues cutáneos, la circunferencia de cintura y de cadera, la composición corporal por bioimpedancia (BIA), la tensión arterial y la autodeclaración de maduración sexual se midieron como indicadores del bienestar físico asociados a enfermedad cardiovascular futura. Resultados: la edad media de los evaluados fue 13,0 ± 2,6 años. Los participantes con mejor desempeño muscular (Q4) presentaron un bienestar físico más saludable en los indicadores IMC, tensión arterial, porcentaje de grasa y circunferencia de cintura, p (X2 lineal) = 0,01. Los individuos con menor desempeño muscular (Q1-3) presentaron 4,06 veces (IC 95% 2,60–6,34; p = 0,043) riesgo de exceso de grasa corporal y 1,57 veces (IC 95% 1,02–1,89; p = 0,020) riesgo de obesidad abdominal. Conclusión: el mejor desempeño muscular se asoció con mejores indicadores del bienestar físico. La evaluación de la fuerza muscular en edades tempranas permitirá implementar programas de prevención de riesgo cardiovascular y metabólico futuros.
