RESUMO
The physical condition was evaluated and the normative reference values were obtained using the Alpha-Fit Battery. The main objective of this study was to establish the percentiles, their respective curves and differences between the sexes for the tests, thus providing an instrument that facilitates the evaluation of physical condition. With a sample of 604 children and adolescents (9-12 years old) with a normal body mass index (BMI) and no conditions that affect their physical performance. A significant difference was evidenced, with a higher average in women, in the measurements of body composition (BMI, height, body weight and skin folds). As well as higher averages in men in the long jump, 20-m shuttle run and shuttle run 4 x 10m. Likewise, there were higher averages in the long jump, shuttle run 4 x 10m and handgrip, as age increased, regardless of sex (AU)
A través de la Batería Alpha-Fit, se evaluó la condición física y obtuvo los valores normativos referenciales. El objetivo principal de este estudio fue establecer los percentiles, sus respectivas curvas y las diferencias entre sexos para las pruebas, brindando así un instrumento, que facilite la evaluación de la condición física. Con una muestra de 604 niños y adolescentes (9-12 años) con un índice de masa corporal (IMC) normal y ninguna condición que afecte su desempeño físico. Se evidencio una diferencia significativa, con mayor promedio en las mujeres, en las medidas de composición corporal (IMC, estatura, peso corporal y pliegues cutáneos). Así como promedios mayores en los hombres en las pruebas de salto de longitud a pies juntos, ida y vuelta 20m y agilidad/velocidad 4x10m. Igualmente, se presentaron mayores promedios en las pruebas de salto de longitud a pies juntos, agilidad/velocidad 4x10m y de presión manual conforme aumenta la edad, independientemente del sexo (AU)

PURPOSE: The aim of this paper is to report the prevalence of cardiovascular risk factors and socioeconomic differences in school-going Ecuadorian adolescents. METHODS: A cross-sectional study was performed from January 2008 until April 2009 in 770 adolescents aged 10 to 16 years old, who attend secondary schools in an urban (Cuenca), and rural area (Nabón) in Ecuador. Data collected for the overall sample included anthropometric variables (weight, height and waist circumference), blood pressure and socio-demographic characteristics. Fasting blood glucose and lipid profile determinations were collected in a subsample of 334 adolescents. RESULTS: The most prevalent cardiovascular risk factors were dyslipidemia (34.2%), abdominal obesity (19.7%) and overweight (18.0%). The prevalence of the remaining cardiovascular risk factors were high levels of blood pressure (6.2%) and obesity (2.1%). Boys were 3.3 times (P < 0.001) more likely to have risk levels of blood pressure. Compared to their peers from lower socioeconomic groups, children from better off socioeconomic strata were 1.5 times (P = 0.048) more likely to be overweight/obese and 1.5 times (P = 0.046) more likely to have abdominal obesity. Overweight and obese children were 4.4 times more likely to have dyslipidemia (P < 0.001). Children living in the rural area were 2.8 times (P = 0.002) more likely to have dyslipidemia than those from the urban area. CONCLUSIONS: Our results demonstrate the advanced levels of the nutrition transition in this Ecuadorian adolescent population. Primary health care should monitor and take actions to address this public health problem in adolescents.
