Objetivo: Efecto de un programa de educación física con intensidad moderada vigorosa sobre el desarrollo motor en niños de preescolar. Método: Participaron 20 alumnos de tercer grado de preescolar, 13 mujeres y 7 hombres, con una edad de 5.05±0.2 años, en un programa de educación física con intensidad moderada a vigorosa adaptado al modelo pedagógico CATCH (avance coordinado para la salud de los niños por sus siglas en inglés), las sesiones se llevaron a cabo 3 veces por semana, durante 12 semanas. La intensidad de la actividad física se determinó mediante el sistema para observar el tiempo de instrucción en la actividad física (SOFIT), antes y después del programa el desarrollo motor fue evaluado mediante el inventario de desarrollo Battelle valorando las variables de coordinación corporal, locomoción, motricidad fina y habilidad perceptiva, que determinan la puntuación de motricidad gruesa y fina. Resultados: La intensidad promedio de la actividad física moderada a vigorosa fue 65% del tiempo total de la clase de educación física, el análisis estadístico mediante el test t-Student para muestras relacionadas, reportó diferencias significativas en la puntuación de motricidad gruesa (p=0.00) y motricidad fina (p=0.00), antes y después de la intervención, el porcentaje de cambio resultó 25.5 Δ% y 11.3 Δ% respectivamente. Conclusión: a pesar que el programa CATCH reporta modestos resultados en variables asociadas a la obesidad en preescolares, su aplicación durante tres meses mostro una influencia positiva para la mejora del desarrollo motor en niños de edad preescolar. Abstract. Objective: To evaluate the effect of a physical education program with moderate-to-vigorous intensity on motor development in kindergarten students. Method: a total of 20 preschool students with average age of 5.05 ± 0.2 years old were involved (13 girls and 7 boys); they carried out a program of physical education at moderate-to-vigorous intensity, based on the pedagogical model of CATCH (Coordinated Approach to Child Health). The program was performed during 3 months, with 3 sessions per week. Intensity of physical activity was determined by the system for observing fitness instruction time (SOFIT), Motor development was determined using the education Battelle developmental inventory, assessing the variables of body coordination, locomotion, fine motor and perceptual ability, which determine the gross and fine motor score. Results: The average engagement time at moderate-to-vigorous physical activity intensity was 65% of the total time of the physical education class. The Student's t-test for related samples was run for the analysis. It reported significant differences in both gross (p=0.00) and fine motor scores (p=0.00), before and after intervention; the percentage of change was 25.5 Δ% and 11.3 Δ%, respectively. Conclusion: Although the CATCH program reports modest results in variables associated with obesity in preschoolers, its application for three months showed positive influence for the improvement of motor development in preschoolers.

Physical Activity Levels

Physical education (PE) lessons are the appropriate occasions to promote physical activity for children. Although the moderate-to-vigorous physical activity (MVPA) levels during PE lessons were investigated in several countries, MVPA levels during PE lessons were never reported at Singapore primary schools. Therefore, the present study aimed to investigate physical activity intensity levels during PE lessons at a Singapore primary school. A total of 93 students (40 girls) voluntary participated in the study: 28 in Grade 1, 39 in Grade 4, and 26 in Grade 6. They were asked to wear an accelerometer on their non-dominant hand in two PE lessons to measure physical activity levels objectively. They also completed questionnaires on their experiences during the PE lessons. The average of the MVPA levels time (%) in the scheduled lesson time across the three grades was 46.98 ± 5.25%, but the average of the MVPA levels time (%) in the actual lesson time was 69.74 ± 7.31%. These results indicated that it would be possible to achieve the recommended MVPA time in PE lessons. The findings of this study would be useful for PE teachers to reflect whether their PE lessons are efficient to promote primary school student’s physical activity levels.

Abstract. Objective: To explore the influence of physical education (PE) lesson context and teacher behaviour on moderate-to-vigorous physical activity (MVPA) in Mexican children during PE class. Methods: Trained observers rated the physical activity intensity (lying down, sitting, standing, walking, vigorous movement) of 232 students from grades 3 to 5, PE lesson context (management, general knowledge, fitness knowledge, fitness, skill practice, game play, free play), and teacher behaviour (promoting fitness, demonstrating, instructing, observing, managing, other task) during PE class in 20 public elementary schools in Mexico City using the System for Observing Fitness Instruction Time (SOFIT). Regressions with backward elimination were conducted. Results: Class duration was on average 33.6 minutes (SD=7.9). Boys (M=14.8 min, SD=6.8) spent more time in MVPA than girls (M=12.6 min, SD=6.1; p<.01). For boys, a model including game play (b= 1.04, p<.001), skill practice (b=.54, p<.01), and fitness (b =.53, p<.05) explained 45% of the variance in MVPA (p<.05). For girls, a model including fitness (b= .49, p<.05), fitness knowledge (b= .19, p<.05), and other task (b=.35, p<.05) explained 38% of the variance in MVPA (p<.05). Conclusion: Strategies and policies aimed at improving child physical activity levels during PE class should endorse the effective instruction and execution of fitness, game play, skill practice and PE lesson contexts.Resumen. Objetivo: Explorar la influencia del contexto de las clases de educación física (EF) y el comportamiento del maestro en la actividad física moderada-vigorosa (AFMV) en niños mexicanos. Métodos: Usando el método Sistema de Observación del Tiempo de Instrucción de la condición Física (SOFIT). Observadores entrenados midieron la intensidad de la actividad física (acostado, sentado, de pie, caminando, movimiento vigoroso) de 232 estudiantes de 3ro a 5to grado, el contexto de la clase, (gestión, conocimiento general, conocimiento de la condición física, condición física, práctica de habilidades, juego, juego libre), y el comportamiento del maestro (promoción de la condición física, demostración, instrucción, observación, gestión, otra tarea) durante la clase de EF en 20 escuelas públicas de educación primaria de la ciudad de México mediante el SOFIT. Se llevaron a cabo regresiones múltiples. Resultados: La duración promedio de las clases observadas fue de 33,6 minutos (DE = 7,9). Los niños (M = 14,8 min, DE = 6,8) pasaron más tiempo en AFMV que las niñas (M = 12,6 min, DE = 6,1; p <0,01). En niños, el tiempo de clase dedicado al juego (β= 1.04, p <.001), la práctica de habilidades (β = .54, p <.01) y la condición física (β = .53, p <.05) explico el 45% de la varianza en AFMV (p <.05). En niñas, el tiempo de clase dedicado a la condición física (β= .49, p <.05), al conocimiento sobre la condición física (β= .19, p <.05), y otras tarea (β= .35, p <.05) explico  el 38% de la varianza en AFMV (p <.05).Para los niños, un modelo incluyendo el juego (b = 1,04, p <0,001), el desarrollo de habilidades prácticas (b = 0,54, p <0,01), y la condición física (b = 0,53, p <0,05) explicaron el 45% de la varianza en AFMV (p <0,05). Para las niñas, un modelo incluyendo la condición física (b = 0,49, p <0,05), el conocimiento de la condición física (b = 0,19, p <0,05), y otras tarea (b = 0,35, p <0,05) explican el 38% de la varianza en AFMV (p <0,05). Conclusión: Las estrategias y políticas encaminadas a la mejora de los niveles de actividad física de los niños durante la clase de EF deben suscribir la enseñanza efectiva y la promoción de la condición física, el juego, y el desarrollo de las habilidades prácticas.

There is a current trend toward using innovative interventions, such as active video gaming to increase physical activity levels among youth with visual impairments. Therefore, the purpose of this study was to compare three video games (Dance, Dance, Revolution [DDR]; EyeToy Kinetic; and Wii Boxing) in allowing youth with visual impairments to achieve time (seconds spent during a 10-min bout) in moderate-to-vigorous physical activity (MVPA). Participants with complete data were youth ( N = 5) with visual impairments aged 10–16 years who played three games for 10-min bouts. Heart rate monitors measured physical activity intensity. A Friedman’s analysis of variance (ANOVA) was used to determine differences between the three interactive video games. Most players were able to achieve time in MVPA in all three games and there was a significant difference in time spent in MVPA, χ2(2) = 7.4, p = .024, with the most time in MVPA from playing EyeToy Kinetic. This study demonstrated that EyeToy Kinetic, Wii Boxing, and DDR are capable of helping youth with visual impairments accrue time in MVPA.

Background:Maternal physical activity declines across gestation, possibly due to changing perception of physical activity intensity. Our purpose was to a) determine whether rating of perceived exertion (RPE) during a treadmill exercise changes at a given energy expenditure, and b) identify the influence of prepregnancy physical activity behavior on this relationship.Methods:Fifty-one subjects were classified as either exercisers (N = 26) or sedentary (N = 25). Participants visited our laboratory at 20 and 32 weeks gestation and at 12 weeks postpartum. At each visit, women performed 5 minutes of moderate and vigorous treadmill exercise; speed was self-selected. Heart rate (HR), oxygen consumption (VO2), and RPE were measured during the last minute at each treadmill intensity.Results:At moderate intensity, postpartum VO2 was higher compared with 20- or 32-week VO2, but there was no difference for HR or RPE. For vigorous intensity, postpartum HR and VO2 were higher than at 32 weeks, but RPE was not different at any time points.Conclusions:RPE does not differ by pregnancy time point at either moderate or vigorous intensity. However, relative to energy cost, physical activity was perceived to be more difficult at 32 weeks compared with other time points. Pregnant women, then, may compensate for physiological changes during gestation by decreasing walking/running speeds.

Guided by the interest-based motivation theory, this study examined the extent to which personal interest and situational interest accounted for boys’ and girls’ learning outcome in a middle school physical education dance unit. Personal and situational interests, physical activity intensity, and skill/knowledge outcome were measured in a random student sample (N = 57). Girls demonstrated higher personal interest in dance than the boys, but both groups were equally motivated with situational interest. Although the girls were not as physically active as boys, their skill/knowledge outcome measures were higher than those of the boys. It appears that gender may have little impact on the motivational effect of situational interest and that girls’ in-class learning might have higher quality than that of boys as a result of higher personal interest. The findings indicate that situational interest may motivate all students, but it is necessary to enhance personal interest in order for them to engage in quality learning.

Background:Despite the plethora of research examining the physical activity-adiposity relation in youth, questions remain regarding the ideal intensity. Therefore, the purpose of this study was to explore the independent effects of physical activity intensity and incidental movement on total and trunk adiposity.Methods:The sample consisted of 1165 youth aged 8 to 17 years from the 2003−04 U.S. National Health and Nutrition Examination Survey. Physical activity (low, moderate, vigorous intensity) and incidental movement (activity level when not physically active) were measured using Actigraph accelerometers over 7 days. Total body and trunk fat were measured using dual-energy X-ray absorptiometry; age- and sex-specific percentile scores were calculated.Results:Bivariate analyses revealed an inverse relation between total, low, moderate and vigorous intensity physical activity with total body and trunk fat. After consideration of the total volume of physical activity in the multivariate analyses, moderate-to-vigorous intensity physical activity remained significantly related to total and trunk fat. Participants with the highest (top 12.5%) moderate-to-vigorous intensity activity values had total fat percentile scores that were 34 points lower than participants with the lowest (bottom 25%) values.Conclusion:These results are consistent with public health guidelines which recommend that children and youth participate in moderate-to-vigorous intensity physical activity.

BACKGROUND A significant proportion of youth in the United Kingdom fail to meet the recommended 60 minutes of moderate-to-vigorous physical activity every day. One of the major barriers encountered in achieving these physical activity recommendations is the perceived difficulty for youths to interpret physical activity intensity levels and apply them to everyday activities. Personalized physical activity feedback is an important method to educate youths about behaviors and associated outcomes. Recent advances in 3D printing have enabled novel ways of representing physical activity levels through personalized tangible feedback to enhance youths’ understanding of concepts and make data more available in the everyday physical environment rather than on screen. OBJECTIVE The purpose of this research was to elicit youths’ (children and adolescents) interpretations of two age-specific 3D models displaying physical activity and to assess their ability to appropriately align activities to the respective intensity. METHODS Twelve primary school children (9 boys; mean age 7.8 years; SD 0.4 years) and 12 secondary school adolescents (6 boys; mean age 14.1 years; SD 0.3 years) participated in individual semistructured interviews. Interview questions, in combination with two interactive tasks, focused on youths’ ability to correctly identify physical activity intensities and interpret an age-specific 3D model. Interviews were transcribed verbatim, content was analyzed, and outcomes were represented via tables and diagrammatic pen profiles. RESULTS Youths, irrespective of age, demonstrated a poor ability to define moderate-intensity activities. Moreover, children and adolescents demonstrated difficulty in correctly identifying light- and vigorous-intensity activities, respectively. Although youths were able to correctly interpret different components of the age-specific 3D models, children struggled to differentiate physical activity intensities represented in the models. CONCLUSIONS These findings support the potential use of age-specific 3D models of physical activity to enhance youths’ understanding of the recommended guidelines and associated intensities.

Purpose: This study aims to (1) establish GENEActiv intensity cutpoints in older adults and (2) compare the classification accuracy between dominant (D) or non-dominant (ND) wrist, using both laboratory and free-living data.Methods: Thirty-one older adults participated in the study. They wore a GENEActiv Original on each wrist and performed nine activities of daily living. A portable gas analyzer was used to measure energy expenditure for each task. Testing was performed on two occasions separated by at least 8 days. Some of the same participants (n = 13) also wore one device on each wrist during 3 days of free-living. Receiver operating characteristic analysis was performed to establish the optimal cutpoints.Results: For sedentary time, both dominant and non-dominant wrist had excellent classification accuracy (sensitivity 0.99 and 0.97, respectively; specificity 0.91 and 0.86, respectively). For Moderate to Vigorous Physical Activity (MVPA), the non-dominant wrist device had better accuracy (ND sensitivity: 0.90, specificity 0.79; D sensitivity: 0.90, specificity 0.64). The corresponding cutpoints for sedentary-to-light were 255 and 375 g · min (epoch independent: 42.5 and 62.5 mg), and those for the light-to-moderate were 588 and 555 g · min (epoch-independent: 98.0 and 92.5 mg) for the non-dominant and dominant wrist, respectively. For free-living data, the dominant wrist device resulted in significantly more sedentary time and significantly less light and MVPA time compared to the non-dominant wrist.

This study investigated the ability of published cut points for the RT3 accelerometer to differentiate between levels of physical activity intensity in children with cerebral palsy (CP). Oxygen consumption (metabolic equivalents; METs) and RT3 data (counts/min) were measured during rest and 5 walking trials. METs and corresponding counts/min were classified as sedentary, light physical activity (LPA), and moderate to vigorous physical activity (MVPA) according to MET thresholds. Counts were also classified according to published cut points. A published cut point exhibited an excellent ability to classify sedentary activity (sensitivity = 89.5%, specificity = 100.0%). Classification accuracy decreased when published cut points were used to classify LPA (sensitivity = 88.9%, specificity = 79.6%) and MVPA (sensitivity = 70%, specificity = 95–97%). Derivation of a new cut point improved classification of both LPA and MVPA. Applying published cut points to RT3 accelerometer data collected in children with CP may result in misclassification of LPA and MVPA.
