Abstract

Objectives: Observational studies have reported an association among physical activity, fitness and lipid profile in youth. The purpose of this study was to analyse the effect of a school-based intervention focused on increasing the number and intensity of Physical Education (PE) sessions a week, on adolescents' lipid profile. Methods: A 4-month group-randomized controlled trial was conducted in 67 adolescents (12-14 years-old) from South-East Spain, 2007. Three school classes were randomly allocated into control group (CG), experimental group-1 (EG1) and experimental group-2 (EG2). The CG received the usual PE in Spain (2 sessions/week), the EG1 received 4 PE sessions/week, and the EG2 received 4 PE sessions/week of high intensity. The main study outcomes were fasting levels of total cholesterol, high-density lipoprotein cholesterol (HDLc), low-density lipoprotein cholesterol (LDLc) and triglycerides. All the analyses were adjusted for sex, sexual maturation, attendance and baseline value of the outcome studied. Results: The intervention did not positively affect cardio-metabolic parameters except for LDLc, that was marginally yet significantly reduced in EG2 (-10.4 mg/dl), compared with the CG (+4.1 mg/dl) (p = 0.04); no differences were observed however for the LDLc/HDLc ratio. No significant effects were observed in EG1. Discussion: Overall, a 4-month school-based physical activity intervention did not substantially influence lipid profile in adolescents. However, the results suggest that increasing both frequency and intensity of PE sessions had a modest effect on LDLc in youth. Future studies involving larger sample sizes and longer interventions should focus on the separate effects of volume and intensity of PE.

Abstract

The purpose of this study was to describe anthropometric and physical fitness characteristics of low-income Chilean preschool children and to examine whether weight status influences children's performance on fitness tests. A total of 434 preschool children (246 boys; 5.48 ± 0.31 years) participated in our study. Anthropometry (weight, height, body mass index -BMI- and waist circumference) and fitness tests (handgrip strength test, standing long jump and 20 m sprint) were assessed by trained nutritionists and physical education teachers, respectively. Significant differences in anthropometry and fitness tests between boys and girls were found. The prevalence of overweight was higher in girls; in contrast to that of obesity. Compared to normal-weight children, overweight/obese boys and girls were heavier and had greater waist circumference (P0.001), were taller (P ≤ 0.002), and showed higher performance in handgrip strength (P ≤ 0.027) but not in standing long jump nor 20 m sprint (P ≥ 0.052). Screening physical fitness levels in overweight/obese preschool children could be an important tool in order to design an efficacy physical activity programme.El objetivo de este estudio fue describir las características antropométricas y el nivel de condición física de preescolares chilenos de bajo nivel socioeconómico y examinar si el estado ponderal influye en el rendimiento de los niños en las pruebas de condición física. Un total de 434 preescolares (246 niños; 5,48 ± 0,31 años) participaron en nuestro estudio. Antropometría (peso, talla, índice de masa corporal –IMC– y perímetro de cintura) y tests de condición física (test de fuerza de prensión manual, test de salto de longitud y 20 m sprint) fueron evaluados por nutricionistas entrenados y profesores de educación física, respectivamente. Se encontraron diferencias significativas en antropometría y tests de condición física entre niños y niñas. La prevalencia de sobrepeso fue mayor en las niñas; en contraste con la de la obesidad. En comparación con los preescolares con normopeso, los niños y niñas con sobrepeso/obesidad pesaron más y tuvieron mayor perímetro de cintura (P0.001), eran más altos (P ≤ 0.002) y mostraron mayor rendimiento en el test de fuerza de prensión manual (P ≤ 0.027), pero no en el test de salto de longitud ni en el test de sprint de 20 m (P ≥ 0.052). Detectar los niveles de condición física en preescolares con sobrepeso/obesidad puede ser una herramienta importante para diseñar programas eficaces de actividad física.
