The levels of physical activity (PA) in the population have decreased, especially at an early age. The aims of the study were: to evaluate the percentage of children meeting PA recommendations for both genders, and to measure steps and PA level at different time intervals during the week. This was an observational cross-sectional study. Seventy-three schoolchildren (36 boys and 37 girls), aged two years (2.12 ± 0.46), were selected to participate in this study. Participants wore an “Actigraph GT3X” accelerometer for seven days to measure the minutes engaged in moderate-to-vigorous physical activity (MVPA) and step volume. The results show 100% of the children studied met the recommended 60 min/day of MVPA, and 50% achieved 120 min/day MVPA and 13,000 steps per day. No gender differences were found. The results of the analysis show a propensity for higher step volumes and PA values from Monday to Friday. In addition, subjects achieved higher step volumes and PA values during “School Time” than “Out-of-School Time”. Given that during “School Time” children showed higher PA and step values, schools represent an important place to help facilitate PA milestones. This study shows the need for further studies and interventions aimed at understanding and improving children’s PA levels at an early age.

Physical activity recommendations for early childhood are gradually being met to a lesser extent today. The objectives of the study were: (i) to assess the degree of compliance with physical activity (PA) recommendations by gender; and (ii) to analyze the level of PA and steps in different periods over a week. This study was an observational cross-sectional study. Sixty-three young children (33 boys and 30 girls) aged two years (2.15 ± 0.35) were recruited for this study. Participants wore a “Garmin vivofit® jr.” activity tracker for seven days, collecting minutes of moderate-to-vigorous physical activity (MVPA) and step volume (Out-of-School Time and School Time). The results show a 50% compliance of the 120 min/day MVPA and 13,000 steps per day. No gender differences were detected. The findings in the analysis indicated a trend towards higher PA and steps at the Weekend. Moreover, participants reached higher PA and steps values “Out-of-School Time” than “School Time” (MVPA) (min/day). This study can provide strategies and motivational PA guidelines at school to enhance well-being at an early age. These activity trackers could stimulate more sustainable forms of urban mobility, such as walking, as the environment would accompany the child to meet daily PA recommendations.

Introducción: La primera etapa escolar podría servir para enseñar hábitos saludables a nivel de alimentación y actividad física (AF). Objetivo: Determinar las diferencias en condición física (CF) en función del grado de adherencia a la dieta mediterránea (DM). Metodología: Se seleccionaron 97 escolares de entre 3 y 6 años, a los que se les evaluó la CF, a través de la batería de FITness en PREescolares (PREFIT); y se determinó su nivel de adherencia a la DM por medio del cuestionario KIDMED. Resultados: Los sujetos mostraron valores de media y alta adherencia a la DM, no existiendo casos de baja adherencia. Existen pocas diferencias, aunque el grupo de media adherencia tiene mejores valores en salto de longitud, equilibrio y velocidad. Conclusión: En el primer periodo infantil aún se observan pocas diferencias entre los sujetos con media y alta adherencia a la DM. Es necesario seguir profundizando en la influencia de factores relacionados con la salud, en poblaciones infantiles para poder proponer en el futuro propuestas de mejora.  Abstract. Background: The first stage of school could serve to teach healthy habits at the level of food and physical activity. Objective: To determine the differences in physical fitness based on the degree of adherence to the mediterranean diet. Methods: 97 schoolchildren between 3 and 6 years old were selected to whom the physical fitness was evaluated throught the FITness battery in PREschool (PREFIT); and their leve lof adherence to the mediterranean diet was determined by means of the KIDMED questionnaire. Results: The subjects cases mean values ​​and high adherence to DM, there are no cases of low adherence. There are few differences, although the group of adhesion means has better values ​​in long jump, balance and speed. Conclusion: In the first infant period there are still few differences between subjects with medium and high adherence to DM. It is necessary to continue to deepen the influence of health-related factors in children's populations in order to propose proposals for improvement in the future.

Los niveles de actividad física (AF) cada vez son más bajos. Las recomendaciones de 60 minutos de actividad física moderada-vigorosa (AFMV) y entre 10.000 y 16.000 pasos al día para niños y adolescentes, solo son cumplidas por grupos minoritarios. Los programas de intervención utilizando dispositivos inteligentes son una buena opción para el incremento de la AF. El objetivo de este estudio fue evaluar el efecto de la utilización de pulseras inteligentes para el incremento de AF en una muestra de un entorno rural. Un total de ocho estudiantes de entre 14 y 16 años participaron en este estudio. Los sujetos portaron una pulsera de actividad física Xiaomi Mi Band 4 durante dos semanas, donde se registró el número de pasos y los minutos de AFMV. La primera Semana de Control (S1), fue una semana de rutina escolar habitual. La segunda Semana de Intervención (S2), fue una intervención de promoción de la AF orientada al incremento de la misma por medio de retos. Los sujetos mostraron en la primera semana una media de 7.200 pasos/día y 173 minutos/día y, durante la segunda, una media de 12.300 pasos/día y 212 minutos/día de AFMV, mostrando así un aumento importante durante la segunda semana, respecto a la primera semana. Diferentes estudios muestran grandes incrementos de AFMV al aplicar programas de intervención, consiguiendo así que se cumplan las recomendaciones mínimas diarias de minutos de AFMV y de pasos. Se evidencia que las pulseras de AF influyen de manera positiva para el aumento de los niveles de AF, además de resultar un instrumento motivante para el alumnado.
