La presente investigación tiene como propósito determinar si existen diferencias en la competencia motriz real y percibida en escolares de contexto rural, en función del sexo y de la participación en actividades deportivas extraescolares; así como determinar la existencia de relaciones entre competencia motriz real, competencia motriz percibida, participación en actividades deportivas extraescolares y tipo de actividad deportiva. Participaron 120 estudiantes de enseñanza primaria (60.0% niñas, edad M=11.05 DE=1.05 años) de la comuna de Perquenco de la Región de La Araucanía, Chile. Se utilizó el Test MOBAK para la evaluación de la competencia motriz real y el Cuestionario SEMOK para la evaluación de la competencia motriz percibida. Los niños presentaron mejores resultados que las niñas en el control de objetos de la competencia motriz real, diferenciándose significativamente (p

Este estudio busca determinar los niveles de competencia motriz de estudiantes chilenos y las posibles diferencias en función del grado y del sexo. Participaron 377 estudiantes (37.7% niñas) de tercer y cuarto básico. La competencia motriz fue evaluada a través del test MOBAK 3-4. Se encontraron bajos niveles de competencia motriz. Los estudiantes de cuarto grado presentan un mejor desempeño motriz que los de tercero. Los niños presentan un mayor desempeño que las niñas en control de objetos, mientras que las niñas obtienen puntajes más altos que los niños en control del cuerpo, aunque con un tamaño del efecto irrelevante. Al contrastar estos resultados con los objetivos del currículum, muchos estudiantes no alcanzan los aprendizajes esperados, siendo necesario poner mayor énfasis en el fomento de la competencia motriz. Abstract. This study aims to determine the levels of motor competence of Chilean students and possible differences according to grade and gender. 377 students (37.7% girls) of the third and fourth grade participated in the study. Motor competence was evaluated through the MOBAK 3-4 test. Low levels of motor competence were found. Fourth grade students showed a better motor performance than third grade students. Boys performed better than girls in object control, while girls scored higher than boys in self-movement, although with an irrelevant effect size. When these results are contrasted with the learning objectives stipulated in the curriculum, many students do not achieve the expected skills, what makes it necessary to place greater emphasis on the promotion of motor competence.

Resumen El presente estudio aborda el análisis del esfuerzo percibido y tiempo en actividades de intensidad moderada y vigorosa en clases de Educación Física, considerando las diferencias según sexo y el estado nutricional de la persona estudiante. Participaron 95 estudiantes de 5° y 6° año de primaria de escuelas de la ciudad de Coyhaique, Chile. Se utilizó la escala EPInfant para la evaluación del esfuerzo percibido y acelerómetros Actigraph GT3X+ para determinar el tiempo en intensidad moderada y vigorosa. En el esfuerzo percibido no se encontraron diferencias significativas según sexo (p=0,144), pero sí según estado nutricional, siendo los estudiantes con obesidad quienes indican una percepción de esfuerzo mayor que el estudiantado de peso normal (p=0,022). En actividades moderadas y vigorosas dentro de la clase de Educación Física, los niños presentan significativamente más minutos en comparación a las niñas (p=0,017); mientras que los escolares normopeso presentarían levemente mayor tiempo en este nivel de intensidad, sin que esta diferencia sea estadísticamente significativa (p=0,622). El esfuerzo realizado en las clases de Educación Física ha sido percibido como más exigente por los escolares con obesidad, y para esto se deben comprender las dificultades físicas y motrices que este grupo presenta. Asimismo, las niñas han participado un menor tiempo en intensidades moderadas y vigorosas, por lo que es pertinente buscar estrategias que permitan aumentar el tiempo de su participación. Abstract This study focuses on the analysis of perceived effort and time of moderate and vigorous activities in physical education classes, considering differences based on gender and the nutritional status of schoolchildren. A total of 95 children in 5th and 6th grade of primary school in the city of Coyhaique, Chile, participated in the study. The EPInfant scale was used to assess the perceived effort, and Actigraph GT3X+ accelerometers were used to determine the time of moderate and vigorous activity. No significant differences were found in the perceived effort by gender (p=0.144); instead, by nutritional status, obese students indicated a higher perceived effort than students with a normal weight (p=0.220). Regarding moderate and vigorous activities in Physical Education class, the boys were significantly more active than the girls (p=0.017). In contrast, normal-weight children were slightly more active at this intensity level, but this difference was not statistically significant (p=0.622). The effort in Physical Education classes has been perceived as more demanding by the obese students; for this reason, it is important to understand the physical and motor difficulties that this group presents. Likewise, girls have participated for a shorter time in moderate and vigorous intensities, being pertinent to look for didactic strategies to increase the time of their participation. Resumo O presente estudo aborda a análise do esforço e do tempo percebido em atividades de intensidade moderada e vigorosa nas aulas de educação física, considerando as diferenças de acordo com o sexo e o estado nutricional de cada estudante. Participaram do estudo noventa e cinco alunos do 5º e 6º ano do ensino fundamental de escolas da cidade de Coyhaique, no Chile. A escala EPInfant foi utilizada para avaliar o esforço percebido e os acelerômetros Actigraph GT3X+ para determinar o tempo em intensidade moderada e vigorosa. Não foram encontradas diferenças significativas na percepção de esforço segundo o sexo (p=0,144), mas foram encontradas diferenças significativas segundo o estado nutricional, com estudantes obesos indicando uma percepção de maior esforço do que estudantes de peso normal (p=0,022). Nas atividades moderadas e vigorosas nas aulas de Educação Física, os meninos apresentam significativamente mais minutos que as meninas (p=0,017), enquanto os estudantes de peso normal apresentaram um pouco mais de tempo nesse nível de intensidade, embora essa diferença não tenha sido estatisticamente significativa (p=0,622). O esforço feito nas aulas de educação física foi percebido como mais exigente por estudantes obesos, e para isso é necessário compreender as dificuldades físicas e motoras que este grupo apresenta. Da mesma forma, as meninas têm participado por um tempo mais curto em intensidades moderadas e vigorosas, por isso é pertinente procurar estratégias para aumentar o tempo da sua participação.

The objective of the present cross-sectional study was to quantify the effect size of overweight on the results of speed-agility in adolescents and to report percentile tables based on sex, age and BMI. Was hypothesized that the effect size obtained from the difference between normal-weight and overweight youth would be equal to or greater than the differences between sexes within the same age group. A total of 10.439 Spanish adolescents aged 13.72 ± 1.42 years from 42 secondary schools participated in the research. Speed-agility was evaluated using the 4x10 m test. The effect size was analysed using the adjusted Hedges’ ğ. The findings regarding sex show that 92.74% and 86.98% of normal-weight and overweight girls, respectively, attained lower speed-agility than boys. With regard to body composition, the percentages are also high, but they are a bit lower than those for sex. So, 77.26% and 70.52% of overweight boys and girls, respectively, showed lower speed-agility than their normal-weight peers. The differential effect size between boys and girls is higher than between normal-weight and overweight adolescents in speed-agility. In spite of this, the results suggest that BMI should be taken into account in assessing the speed-agility of young people. Resumen. El objetivo de este estudio transversal fue cuantificar el tamaño del efecto del sobrepeso en los resultados de velocidad-agilidad en adolescentes e informar las tablas de percentiles en función del sexo, la edad y el IMC. Se planteó la hipótesis de que el tamaño del efecto obtenido entre los jóvenes con sobrepeso y normopeso sería igual o mayor que las diferencias entre los sexos dentro del mismo grupo de edad. Un total de 10.439 adolescentes españoles de 13.72 ± 1.42 años de 42 centros de educación secundaria participaron en la investigación. Se evaluó la velocidad-agilidad utilizando la prueba de 4x10 m. El tamaño del efecto se analizó ajustando por la prueba ğ de Hedges. Los resultados con respecto al sexo muestran que el 92.74% y el 86.98% de las niñas con sobrepeso y normopeso, respectivamente, alcanzaron una velocidad-agilidad menor que los niños. Con respecto a la composición corporal, los porcentajes también son altos, pero son un poco más bajos que los del sexo. El 77.26% y 70.52% de los niños y niñas con sobrepeso, respectivamente, mostraron menor velocidad-agilidad que sus pares de peso normal. Como conclusión, el tamaño del efecto diferencial entre niños y niñas es mayor que entre adolescentes con normopeso y sobrepeso en velocidad-agilidad. A pesar de esto, los resultados sugieren que se debe tener en cuenta el IMC al evaluar la velocidad-agilidad de los jóvenes.

The main aim of the study was to investigate the reasons that motivate secondary school pupils to practise physical exercise, and how these motives are related to their perception of the climate in physical education classes. Participants: The sample consisted of 448 subjects, 36.8% girls and 63.2% boys, aged between 16 and 19 years (M = 17.61, SD = 0.96). The methodology was a descriptive cross-sectional study. Two instruments were applied: self-reporting by the pupils of their motives for practising physical exercise, and a questionnaire on their attitudes towards teachers’ behaviour and the physical education programme. The results showed that the strongest motive for the practice of physical exercise was “Prevention and positive health” (M = 5.29, SD = 1.45). In conclusion, there is a weak correlation among the pupils’ motives for practising physical exercise and their perception of the climate in class.

Given the importance of physical activity and sleep for health, different recommendations have been proposed for the pediatric population. The objective of this study was to determine the association between physical activity and sleep recommendations compliance and excess weight in school children from Temuco, Chile.Physical activity and sleep were measured using ActiGraph wGT3X-BT® accelerometers. Excess weight was categorized on two categories: absence (normal weight) or presence (overweight or obesity) based on body mass index.A total of 183 school children participated (54.1 % were females; mean age = 10.95 ± 1.07). Of them, 85.4 % did not meet physical activity recommendations, whereas 75.6% did not meet sleep recommendations. Significant differences were observed in favor of boys over girls in relation to moderate and vigorous physical activity (p = 0.002), but this was not the case for amount of sleep. School children with excess weight showed less time spent in moderate and vigorous activity (p = 0.004) and a lower amount of sleep (p = 0.010) than normal weight ones. Non-compliance with physical activity recommendations was associated with excess weight (odds ratio [OR] = 8.178; 95 % confidence interval [CI]: 1.465-45.635; p = 0.017), but this was not observed in relation to sleep recommendations.A high percentage of school children do not meet the recommendations for physical activity and sleep. Associations were observed by sex and presence of excess weight. Strategies are required to promote compliance with these recommendations in the pediatric population.Introducción. Dada la importancia que la actividad física y el sueño han adquirido para la salud, se han propuesto diversas recomendaciones para la población infantil. El propósito de este estudio fue determinar cómo se asocia el cumplimiento de las recomendaciones de actividad física y de sueño con el exceso de peso. Población y métodos. Para la medición de la actividad física y el sueño, se utilizaron acelerómetros ActiGraph wGT3X-BT®. Se determinó el índice de masa corporal para las categorizaciones de ausencia (peso normal) o presencia (sobrepeso-obesidad) de exceso de peso. Resultados. Participaron 183 escolares (54,1 % eran niñas, edad M = 10,95 ± 1,07). El 85,4 % no cumple con las recomendaciones de actividad física, mientras que el 75,6 % no cumple con las recomendaciones de sueño. Los niños se diferencian significativamente de las niñas en tiempo de actividades físicas moderadas y vigorosas (p = 0,002), mas no así en cantidad de sueño. Los escolares con exceso de peso presentan menos tiempo de actividades de intensidad moderada y vigorosa (p = 0,004) y una menor cantidad de sueño (p = 0,010) que los escolares de peso normal. El no cumplir las recomendaciones de actividad física se asociaría con el exceso de peso (razón de momios [OR, por su sigla en inglés] = 8,178; intervalo de confianza del 95 % [IC95 %]: 1,465-45,635; p = 0,017), lo que no se observó en las recomendaciones de sueño. Conclusiones. Un alto porcentaje de escolares no cumplen con las recomendaciones de actividad física y cantidad de sueño. Se observaron asociaciones según el sexo y la presencia de exceso de peso. Es necesario desarrollar estrategias para fomentar el cumplimiento de estas recomendaciones en la población infantil.

(1) Background: The association between actual and perceived motor competence (MC) is one of the underlying mechanisms that influence the practice of physical activity. This study mainly aimed to analyze the structure and correlations between actual and perceived MC in schoolchildren and to compare actual and perceived MC between girls and boys. (2) Methods: A total of 467 fifth and sixth graders (43.9% girls, M = 11.26, SD = 0.70) participated. Actual and perceived MC were assessed. To examine the proposed four factor models, structural equation models (factor analyses, latent correlations, invariance testing for gender) were conducted. Student t-test for independent samples was used to compare boys and girls. (3) Results: Proposed models achieved acceptable fit values with moderate correlation between the factors according to the type of MC in actual and perceived MC. Invariant factor structure in boys and girls was revealed. Boys performed and perceived themselves higher in object control than girls, whereas girls showed higher actual and perceived self-movement than boys. (4) Conclusions: The association between actual and perceived MC exists both globally and separately by gender, despite the differences between boys and girls. It is important to consider the role of gender and type of MC in the development of motor competencies, as well as in the strengthening of the children&rsquo, s sense of competence.

The development of motor competencies is one of the most important objectives of physical education, and therefore it is necessary to assess it from a pedagogical approach using valid instruments. The MOBAK battery is designed to assess basic motor competencies in primary education. It differentiates by the stage in the curriculum, and proposes a two-factor structure corresponding to the basic motor competencies of object movement and self-movement. This study has three objectives: to determine the construct validity of three test instruments of the MOBAK battery for assessing motor competencies; to determine how gender, BMI, and age covariates relate to motor competencies; and to examine the level of basic motor competencies of primary school children in Chile. A total of 1,785 children (45.7% girls) were assessed, divided into 1st and 2nd grade (MOBAK 1-2; 559 children; 50.6 % girls), 3rd and 4th grade (MOBAK 3-4; 496 children, 39.3 % girls), and 5th and 6th grade (MOBAK 5-6; 730 children, 46.3 % girls). The construct validity of each section was analysed using the confirmatory factorial analysis (CFA). The results confirm the two-factor structure in all sections of the MOBAK battery, they confirm the relationship between motor competencies and the covariates gender, BMI, and age, and they show that Chilean primary school children have low levels of motor competence, especially in 5th and 6th grade. The MOBAK battery is a suitable instrument for the assessment of basic motor competencies in primary education and is a diagnostic and monitoring tool for pedagogical practices and educational research. El desarrollo de la competencia motriz es uno de los objetivos más importantes de la Educación Física, por lo que es necesario que su diagnóstico se realice desde un enfoque pedagógico, mediante instrumentos válidos. La batería MOBAK ha sido diseñada para la evaluación de las competencias motrices básicas en educación primaria, considerando una diferenciación según el grado curricular, planteando una estructura de dos factores correspondientes a las competencias motrices de control de objetos y control del cuerpo. Este estudio se plantea tres objetivos: determinar la validez de constructo de tres tramos de la batería MOBAK para la evaluación de las competencias motrices; determinar la relación de las covariables sexo, IMC y edad con las competencias motrices; y examinar las competencias motrices básicas de escolares de primaria de Chile. En total 1785 escolares de primaria (45.7 % niñas) fueron evaluados, divididos en el tramo de 1.° y 2.° grado (MOBAK 1-2; 559 escolares, 50.6 % niñas); en el tramo de 3.° y 4.° grado (MOBAK 3-4; 496 escolares, 39.3 % niñas); y en el tramo de 5.° y 6.° grado (MOBAK 5-6; 730 escolares, 46.3 % niñas). analizó la validez de constructo para cada uno de los tramos mediante análisis factoriales confirmatorios (AFC). Los resultados confirman la estructura de dos factores en todos los tramos de la batería MOBAK, confirman la relación de las covariables sexo, IMC y edad con las competencias motrices y evidencian que los escolares chilenos poseen bajos niveles de competencia motriz, especialmente en el tramo de 5.° y 6.° de primaria. La batería MOBAK se presenta como instrumento adecuado para la evaluación de las competencias motrices básicas en educación primaria, sirviendo de herramienta de diagnóstico y seguimiento tanto para las prácticas pedagógicas como para la investigación educativa.

Global changes require urgent integration of health and wellbeing into all urban policies. Complex social and environmental factors define wellbeing outcomes and inequities present in cities. Additionally, political decisions are seldom thought and developed considering the needs and participation of children and adolescents. The REDibuja study aims to develop a multidimensional framework of wellbeing for children and adolescents and to validate an index of opportunities for better wellbeing for children and adolescents in the urban context of Temuco, Chile. This child-centered and cross-sectional study will involve mixed methodologies throughout the implementation of five work packages for two years (2022–2023): (1) development of a conceptual framework for child and adolescent wellbeing, (2) integration of available and public data, (3) studies in the local context, (4) data integration using geographic information systems, and (5) validation of the wellbeing opportunity index for children and adolescents. REDibuja will implement methodologies that until now are little used to facilitate political decisions in our regional context. This process and results could be transferred for assessment and decision-making in Latin America and low- and middle-income countries in other regions.

El propósito del estudio fue determinar el nivel de relación entre indicadores antropométricos segmentarios de muscularidad con los niveles de potencia expresados en la fuerza explosiva y elástico-explosiva. Para ello se evaluó a 31 deportistas varones (edad = 15,5 ± 1,7 años; peso = 61,4 ± 11,5 kg) de diversas disciplinas del Programa de Proyección Deportiva Nacional de la Región de Aysén, Chile, a través de los protocolos de la ISAK para las evaluaciones antropométricas y test de Bosco para la valoración de potencia de salto, tras lo cual se observó una alta intensidad de asociación entre potencia absoluta de los saltos SJ y CMJ, y todos los parámetros antropométricos de muslo (r >0,8). Con ello se logró establecer un modelo predictivo del rendimiento en salto mediante 3 mediciones antropométricas. Abstract The purpose of this study was determined the level of relation between anthropometric segmental indicators of muscularity with the power levels expressed in the explosive and elastic strength, to carry it out 31 male athletes were (Age = 15.5 ±1.7 years; Weight = 61.4 ±11.5 kg) of diverse disciplines from the Program of National Sportive Projection of the Region of Aysén-Chile, were evaluated. The protocols of the ISAK for the anthropometric evaluations and Test of Bosco for the assessment of power of jump were followed. Results: An association between absolute power of the jumps SJ and CMJ and all the anthropometric variables of thigh (r > 0,8) it was able to establish a predictive model of the performance in jump by means of 3 anthropometric measurements has been established. Resumo O objetivo deste trabalho foi determinar o nível de relação entre indicadores antropométricos segmentários de muscularidade com os níveis de potência expressados na força explosiva e elástico explosiva. Para tal, avaliaram-se a 31 esportistas varões (idade = 15,5 ± 1,7 anos; peso = 61,4 ±11,5 kg) de diversas disciplinas do Programa de Projeção Esportiva Nacional da Região de Aysén, Chile. Seguiram-se os protocolos da ISAK para as avaliações antropométricas e teste de Bosco para a valoração de potência de salto. Observa-se uma alta intensidade de associação entre potência absoluta dos saltos SJ e CMJ e todas as variáveis antropométricas da coxa (r > 0,8). Estabeleceu-se um modelo preditivo do rendimento em salto mediante três medidas antropométricas.

Background Latin America and the Caribbean (LAC) countries, have been historically under-represented due to the lack of surveillance of physical behaviours in young populations. Therefore, the aim of this study was to describe and compare overall physical activity (PA), active transportation to and from school (i.e. walking or cycling), physical education (PE) participation, and sedentary behaviour (SB) in adolescents from 26 countries in LAC. Methods Data were collected in the Global School-based Student Health Survey (2007-13). Prevalences for each physical behaviour were compared by sex across the region. Results In total, 64 034 adolescents provided complete data (age range: 11 to 18 years; 47.7% male). Only about 15% of adolescents in LAC countries were physically active (at least 60 min/day of moderate-to-vigorous PA) with most countries showing sex disparities. Overall, 41.9% reported being active for transportation to and from school at least 3 days per week. In 12 countries, at least 50% of the adolescents reported sitting ≥3 h per day outside school, and a third of adolescents reported participation in PE classes on 3 days or more per week. Conclusions The study sets a challenge for the LAC region, as physical inactivity and SB are highly prevalent across all countries. Gender inequity was shown in most countries, with boys reporting more active behaviours. Regional and national actions for implementing policies to revert this situation are urgent.

Resumen Martinez-Lopez, N., Espinoza-Silva, M. y Carcamo-Oyarzun, J. (2021). Competencia motriz en escolares de primer y segundo año de primaria en la región La Araucanía, Chile. PENSAR EN MOVIMIENTO: Revista de Ciencias del Ejercicio y la Salud, 19(2), 1-16. La competencia motriz es un componente importante para la participación en la cultura del juego, deportes y actividad física, por lo que su desarrollo es fundamental en el inicio de la trayectoria escolar. Este estudio tuvo como propósitos: describir el desempeño en la competencia motriz de Control de Objetos y Control del Cuerpo de estudiantes de primer y segundo grado de primaria de Chile; determinar la relación entre la competencia motriz y la edad; y establecer la existencia de posibles diferencias según el sexo de los estudiantes. Se utilizó un enfoque cuantitativo, siendo un estudio no experimental de corte transversal y de tipo descriptivo-correlacional. Participaron 289 escolares (51.2% niñas, 48.8% niños) de entre seis y ocho años de cinco establecimientos educacionales de la región de La Araucanía, Chile. Se utilizó el test MOBAK 1-2 para la evaluación de la competencia motriz en dos dimensiones (Control de Objetos y Control del Cuerpo). Para establecer la relación entre competencia motriz y edad se utilizó el coeficiente rho de Spearman, y para determinar la existencia de diferencias según sexo se utilizó la prueba U de Mann-Whitney, determinando el tamaño del efecto a través del cálculo de probabilidad de superioridad (PS). Los resultados indican que la edad se relaciona de forma positiva con el Control de Objetos (p < .001, r = .315) y el Control del Cuerpo (p < .001, r = .261). Al comparar los desempeños motrices según sexo, los niños presentan mejores resultados que las niñas en tareas motrices asociadas al Control de Objetos (U = 13533.000, Z = 4.439, p < .001, PSest = .61), mientras que en Control del Cuerpo no se encontraron diferencias estadísticamente significativas. Tanto la edad como el sexo de los estudiantes son variables asociadas al desarrollo de la competencia motriz. Estos resultados aportan información relevante para diseñar estrategias pedagógicas que busquen fomentar la competencia motriz de manera óptima y equitativa. Abstract Martinez-Lopez, N., Espinoza-Silva, M. & Carcamo-Oyarzun, J. (2021). Motor competence in first- and second-grade schoolchildren in The Araucanía, Chile. PENSAR EN MOVIMIENTO: Revista de Ciencias del Ejercicio y la Salud, 19(2), 1-16. Motor competence is a significant component for participation in the culture of play, sports, and physical activity. Its development is therefore key at the early stages of a child’s journey through the educational system. The purposes of this study were to describe performance in the motor competence of Object Control and Body Control in first- and second-grade elementary school students in Chile, to determine the relationship between this motor competence and age, and to establish the existence of potential sex-related differences among the students. A quantitative approach was used, as this was a non-experimental, cross-sectional, descriptive-correlational study. Participants included 289 schoolchildren (51.2% girls, 48.8% boys) between six and eight years of age in five schools of the region of La Araucanía, Chile. The MOBAK 1-2 test was used for assessing the motor competence in two dimensions (Object Control and Body Control). In order to establish the relationship between motor competence and age, Spearman’s rho coefficiient was used; and Mann-Whitney’s U test was used to determine the existence of sex-related differences, determining the extent of the effect through superiority probability (SP) calculation. The results indicate that age is positively related to Object Control (p < .001, r = .315) and Body Control (p < .001, r = .261). When comparing motor performances according to sex, boys showed better results than girls in motor tasks associated to Object Control (U = 13533.000, Z = 4.439, p < .001, PSest = .61), whereas no statistically significant differences were found in Body Control. Both age and sex in students are variables associated to the development of this motor competence. These results provide relevant information for designing pedagogical strategies that seek to foster motor competence in an optimal, equitable manner. Resumo Martinez-Lopez, N., Espinoza-Silva, M. e Carcamo-Oyarzun, J. (2021). Competência motora em escolares do primeiro e segundo ano do ensino fundamental na região de La Araucanía, Chile. PENSAR EN MOVIMIENTO: Revista de Ciencias del Ejercicio y la Salud, 19(2), 1-16. A competência motora é um componente importante para a participação na cultura do jogo, do esporte e da atividade física, por isso seu desenvolvimento é fundamental no início da trajetória escolar. O objetivo deste estudo foi descrever o desempenho na competência motora do Controle de Objetos e Controle Corporal de escolares do primeiro e do segundo ano do Ensino Fundamental no Chile; determinar a relação entre competência motora e idade; e estabelecer a existência de possíveis diferenças de acordo com o sexo dos estudantes. Utilizou-se uma abordagem quantitativa, sendo um estudo transversal e descritivo-correlacional não experimental. Participaram 289 estudantes (51,2% meninas, 48,8% meninos) entre seis e oito anos de cinco instituições de ensino da região de La Araucania, no Chile. O teste MOBAK 1-2 foi utilizado para a avaliação da competência motora em duas dimensões (Controle de Objetos e Controle Corporal). Para estabelecer a relação entre competência motora e idade, foi utilizado o coeficiente rô de Spearman, e para determinar a existência de diferenças de acordo com o sexo, foi utilizado o teste U de Mann-Whitney, determinando o tamanho do efeito por meio do cálculo da probabilidade de superioridade (PS). Os resultados indicam que a idade está positivamente relacionada ao Controle de Objetos (p< 0,001, r= 0,315) e Controle corporal (p< 0,001; r = 0,261). Ao comparar o desempenho motor por sexo, os meninos apresentam melhores resultados do que as meninas em tarefas motoras associadas ao Controle de Objetos (U= 13533,000; Z = 4,439; p < 0,001; PSest = 0,61), enquanto no Controle Corporal não foram encontradas diferenças estatisticamente significativas. Tanto a idade quanto o sexo dos estudantes são variáveis associadas ao desenvolvimento da competência motora. Esses resultados fornecem informações relevantes para a concepção de estratégias pedagógicas que buscam promover a competência motora de forma ideal e equitativa.

Background: The study summarizes the findings of the 2018 Chilean Report Card (RC) on Physical Activity (PA) for Children and Adolescents and compares the results with the first Chilean RC and with other countries from the Global Matrix 3.0. Methods: A Research Work Group using a standardized methodology from the Global Matrix 3.0 awarded grades for 13 PA-related indicators based on the percentage of compliance for defined benchmarks. Different public data sets, government reports, and papers informed the indicators. Results: The grades assigned were for (1) “behaviors that contribute to overall PA levels”: overall PA, D−; organized sport participation, D−; active play, INC; and active transportation, F; (2) “factors associated with cardiometabolic risk”: sedentary behavior, C−; overweight and obesity, F; fitness, D; sleep, INC; and (3) “factors that influence PA”: family and peers, F; school, D; inclusion, INC; community and built environment, B; government strategies and investments, B−. Conclusions: Chile’s grades remained low compared with the first RC. On the positive side, Chile is advancing in environmental and policy aspects. Our findings indicate that the implementation of new strategies should be developed through collaboration between different sectors to maximize effective investments for increasing PA and decreasing sedentary time among children and adolescents in Chile.

espanolIntroduccion: actualmente, el ejercicio fisico practicado de manera regular es la mejor herramienta disponible para fomentar el bienestar de las personas y una mejor salud. Objetivo: el objetivo del estudio fue determinar el nivel de condicion fisica y el estado nutricional, asi como la relacion entre estos, en estudiantes de ensenanza basica de la ciudad de Chillan. Metodos: el estudio es de tipo descriptivo, de corte transversal y relacional. Participaron 2500 estudiantes. Para evaluar la condicion fisica se utilizaron los siguientes test: Wells y Dillons (flexibilidad), Sargent Test (potencia miembros inferiores), Test de 1 Milla de la AAPHARD (capacidad aerobica) y Abdominales en 30 segundos (capacidad muscular localizada). Resultados: al comparar por sexos, los hombres presentaron diferencias estadisticas significativas en las variables fisicas de capacidad aerobica (p = 0,00), abdominales (p = 0,00) y salto (p = 0,00); solo en el caso de la flexibilidad las mujeres presentaron mejores resultados (p = 0,01). Al relacionar el IMC con la capacidad fisica se observa una relacion negativa en ambos sexos, es decir: a mayor IMC, menor es la cantidad de abdominales realizados (r = -0,032; r = -0,084, mujeres y hombres, respectivamente) y la capacidad aerobica (r = -0,063 y r = -0,023, mujeres y hombres, respectivamente). En flexibilidad y salto se observa una correlacion positiva, aunque esta es insignificante. Conclusion: los hombres y las mujeres con normopeso presentan una mejor condicion fisica en comparacion con quienes presentan sobrepeso u obesidad. En cuanto al sexo, los hombres presentan una mejor condicion fisica salvo en la prueba de flexibilidad, donde las mujeres presentan los mejores resultados. Ademas, se observa una relacion negativa en ambos sexos entre la condicion fisica y la composicion corporal, donde un IMC elevado se traduce en un bajo nivel de rendimiento fisico. EnglishIntroduction: currently, regular physical exercise is the best tool available to promote people’s well-being and improve their health. Objective: the objective of the study was to determine the level of physical condition and nutritional status, as well as the relationship between them, in elementary school students in the city of Chillan. Methods: the study is of the descriptive, cross-sectional, relational type. A total of 2500 students participated. To evaluate physical condition, the followingtests were used: Wells and Dillons (flexibility), Sargent Test (lower limb power), AAPHARD’s 1-Mile Test (cardiorespiratory resistance), and Sit-ups in 30 seconds (localized muscular resistance). Results: when comparing by sex, men presented significant statistical differences in the physical variables of aerobic capacity (p = 0.00), situps (p = 0.00) and jumping (p = 0.00); only in the case of flexibility did women present better results (p = 0.01). When relating BMI to physical capacity a negative relationship is observed in both sexes—that is, the higher the BMI, the lower the amount of sit-ups (r = -0.032; r = -0.084, women and men, respectively) and aerobic capacity (r = -0.063 and r = -0.023, women and men, respectively). In flexibility and jump a positive though negligible correlation was observed. Conclusion: normal-weight men and women have a better physical condition as compared to those with overweight or obesity. As for sex, men have a better physical condition except for the flexibility test, where women obtain the best results. In addition, a negative relationship is observed in both sexes between physical condition and body composition, where a high BMI results in a low level of physical performance.

One of the cornerstones of a physically active lifestyle is Motor Competence (MC). MC is a complex biocultural attribute and therefore, its study requires a multi-sectoral, multi-, inter- and transdisciplinary approach. MC is a growing area of research, especially in children and adolescents due to its positive association with a plethora of health and developmental outcomes. Many questions, however, remain to be answered in this field of research, with regard to: (i) Health and Developmental-related Associations of MC; (ii) Assessment of MC; (iii) Prevalence and Trends of MC; (iv) Correlates and Determinants of MC; (v) MC Interventions, and (vi) Translating MC Research into Practice and Policy. This paper presents a narrative review of the literature, summarizing current knowledge, identifying key research gaps and presenting questions for future investigation on MC in children and adolescents. This is a collaborative effort from the International Motor Competence Network (IMCNetwork) a network of academics and researchers aiming to promote international collaborative research and knowledge translation in the expansive field of MC. The knowledge and deliverables generated by addressing and answering the aforementioned research questions on MC presented in this review have the potential to shape the ways in which researchers and practitioners promote MC and physical activity in children and adolescents across the world., Portuguese Foundation for Science and Technology FCT/UIDB/00617/2020 CEECIND/01089/2017 CEECIND/01069/2017, Grant Agency of the Czech Republic 19-03276S, Spanish Ministry of Economy and Competitiveness RTI2018-095284-J-100, Spanish Ministry of of Science and Innovation RYC2019-027287-I, National Commission for Scientific Research and Technology of Chile (CONICYT-FONDECYT) 11170525, University of Granada Plan Propio de Investigacion, European Commission, Junta de Andalucia SOMM17/6107/UGR, Miguel Servet Fellow (Instituto de Salud Carlos III-FSE) CP18/0150

Resumen Introducción. La obesidad infantil es un problema grave de salud pública, ya que genera resultados adversos para la salud física y mental. Objetivo. Relacionar el estado nutricional con los niveles de autoestima y rendimiento físico en escolares de 8 a 10 años de edad. Materiales y métodos. Participaron 236 escolares: 117 hombres y 119 mujeres, de entre 8 y 10 años de edad, pertenecientes a dos colegios del municipio de Temuco con carácter estatal-municipal. Se evaluó peso, talla, índice de masa corporal, porcentaje de masa/grasa, contorno cintura, condición física, horas de ejercicio físico a la semana y autoestima. Resultados. El 43.6% de los escolares presentó malnutrición por exceso. Los categorizados como obesos (19%) presentaron niveles superiores en masa grasa y contorno cintura (p 0.05). Conclusiones. La obesidad en edad escolar pone de manifiesto alteraciones asociadas con el rendimiento físico, la masa grasa y las tendencias negativas sobre la autoestima. A pesar de ser una etapa temprana, sepuedenapreciarlas consecuencias asociadasaestacondición. Abstract Introduction: Childhood obesity is a serious public health issue, since it generates adverse results for physical and mental health. Objective: To correlate nutritional status and levels of self-esteem and physical performance in schoolchildren aged between 8 and 10. Materials and methods: 236 students participated, 117 male and 119 female, aged between 8 and 10, from two public schools in the municipality of Temuco. Weight, height, body mass index, mass/ fat percentage, waist contour, physical condition, hours of physical exercise per week and self-esteem were evaluated. Results: Overnutrition was documented in 43.6% of the students; children classified as obese (19%) presented higher levels of fat mass and waist contour (p0.05). Conclusions: Obesity in school-aged children reveals alterations associated with physical performance, fat mass and negative trends on self-esteem. Despite developing at an early stage, the consequences associated with this condition can already be seen.
