Background: To evaluate the progression of physical fitness (PF), basic motor competence (BMC), and executive function (EF) over one year in children aged 4-5 years at a health center. Methods: In this longitudinal analysis, children's BMC was evaluated using the MOBAK KG test for object and self-movement. The PREFIT Battery gauged PF through handgrip strength, standing long jump, and other fitness measures, while the Early Years Toolbox appraised EF. Results: Adjustments for confounding factors showed notable improvements in BMC, particularly in object movement (OM; mean difference 0.789, p=0.044) and self-movement (SM; mean difference 0.842, p=0.037), with overall MOBAK scores also increasing (mean difference 1.632, p=0.018). Enhancements in the standing long jump (mean difference 9.036 cm, p=0.014) and EF tasks "Mr. Ant" (mean difference 0.669, p<0.001) and "Go/No-Go" (mean difference 0.120, p<0.001) were evident, signifying substantial BMC gains and some progress in PF and EF. Conclusion: This research underscores the positive impact of regular training on BMC and PF in young children. Significant BMC development and associated improvements in PF and EF over the study period highlight the importance of structured activities in early childhood. These findings advocate for standardized training programs to enhance childhood health and encourage active lifestyles.

Background: The role of muscular fitness (as a protecting factor for an optimal immune system) and WBC count remains unclear. To the best of our knowledge, this is the first study to investigate the relationship between the total count of WBC and groups based on handgrip strength and body composition. The aim of this study was to elucidate the relationship between handgrip strength and WBC count in a nationally representative sample of adolescents from the U.S. Methods: We used data from the NHANES cross-sectional study (waves 2011 to 2014). The final analysis included 917 adolescents from 12–17 years old (51.0% boys). Normalized handgrip strength (kg) (NHS) was relativized by body composition parameters (body weight [NHSw], total body fat [NHSf], and trunk fat [NHSt]) assessed with dual energy X-ray absorptiometry. Results: An inverse association was found between total WBC count and all assessments of low NHS in both sexes (p < 0.05). Both boys and girls with low NHS had higher WBC counts in all estimations of NHS than those with high NHS (p < 0.05 for all). All estimations of low NHS showed significant differences with those with intermediate NHS (only in girls) (p < 0.05 for all). Girls with intermediate NHSt exhibited higher WBC count than those with high NHSt (p = 0.004). Conclusions: Our findings suggest that greater levels of NHS are linked to lower total WBC counts. From a public health perspective, our findings are clinically significant and emphasize the relevance of improving muscular fitness during adolescence since it may contribute to boosting the immune system among adolescents.

Background The measurement of physical ftness has a history that dates back nearly 200 years. Recently, there has been an increase in international research and surveillance on physical ftness creating a need for setting international priorities that could help guide future eforts. Objective This study aimed to produce a list of the top 10 international priorities for research and surveillance on physical ftness among children and adolescents. Methods Using a twin-panel Delphi method, two independent panels consisting of 46 international experts were identifed (panel 1=28, panel 2=18). The panel participants were asked to list up to fve priorities for research or surveillance (round 1), and then rated the items from their own panel on a 5-point Likert scale of importance (round 2). In round 3, experts were asked to rate the priorities identifed by the other panel. Results There was strong between-panel agreement (panel 1: rs=0.76, p<0.01; panel 2: rs=0.77, p<0.01) in the priorities identifed. The list of the fnal top 10 priorities included (i) “conduct longitudinal studies to assess changes in ftness and associations with health”. This was followed by (ii) “use ftness surveillance to inform decision making”, and (iii) “implement regular and consistent international/national ftness surveys using common measures”. Conclusions The priorities identifed in this study provide guidance for future international collaborations and research eforts on the physical ftness of children and adolescents over the next decade and beyond.

(Arán Ediciones, 2022) Atencio Osorio, Miguel Alejandro; Carrillo Arango, Hugo Alejandro; Ramírez Vélez, Robinson; Ciencias de la Salud; Osasun Zientziak
Objetivo: la condición física es uno de los factores predictores más relevantes del estado de salud mental de un individuo. No obstante, son pocos los estudios que han descrito la relación entre la condición física con síntomas depresivos en universitarios latinos. El objetivo del presente estudio fue verificar la posible relación entre la condición física y los síntomas depresivos en un colectivo de estudiantes universitarios. Métodos y procedimientos de investigación: estudio transversal en 344 universitarios (53 % mujeres) entre los 18 y 25 años (rango 18-23 años), pertenecientes a cuatro instituciones de educación superior de Cali, Colombia. Los síntomas depresivos se recogieron por autoinforme a través del inventario de Depresión Beck-II. Los componentes de la condición física (salto alto, flexiones de brazo, flexiones de tronco y condición aeróbica) se midieron a través de pruebas de campo. El promedio de las 4 variables de condición física se tipifico y transformaron como Z-score para establecer una única variable denominada índice general de condición física. Posteriormente se categorizó en tertiles (T), siendo el tertil (T3) la posición con mejor desempeño físico. Resultados: un 12 % de la población presentó síntomas depresivos leves, mientras que un 10 % presentaron depresión moderada/grave, siendo las mujeres las que acusaron mayor puntaje en el inventario de Depresión Beck-II. En el grupo de hombres, correlaciones inversas y estadísticamente significativas fueron observadas entre los valores de depresión con la escala Beck-II, con el componente de salto alto (Z-score) r = -0,190, la condición aeróbica (Z-score) r = -0,195, y con el índice general de condición física (Z-score) r = -0,189; p < 0,01. Esta misma relación, fue observada tras ajustar por la edad, tabaquismo, enolismo y actividad física semanal como covariable, en los hombres entre los terciles 1 y 3 (p = 0,028). Conclusión: los resultados obtenidos en el presente trabajo revelan que el salto alto y el índice general de condición física de los hombres se relacionan de manera inversa y significativa con el puntaje del inventario de Depresión de Beck-II.

Introducción: la falta de actividad física y el sedentarismo en niños se asocia con una mayor adiposidad, bajo nivel de aptitud cardiovascular y riesgo de enfermedades cardiovasculares. Sin embargo, cumplir con las recomendaciones de actividad física se relaciona con mejoras en la salud mental, disminución de la ansiedad y depresión, así como adopción de hábitos saludables. Objetivos: evaluar la relación entre los diferentes dominios de la actividad física y del sedentarismo, medidos de forma objetiva, y los componentes de la condición física en niños españoles de 4 y 5 años. Población y métodos: estudio transversal dentro del proyecto 'Observatorio y programa de intervención de ejercicio físico y estilos de vida en familia para niños y niñas de 4 a 5 años en Atención Primaria' (https://observatorioactividadfisica.es). La condición física se evaluó con la batería PREFIT y la cantidad e intensidad de actividad física mediante un acelerómetro tri-axial GENEActiv durante 7 días consecutivos las 24 horas del día. Resultados: la muestra evaluada fue de 70 niños (38 niños y 32 niñas) con una media (intervalo de confianza [IC] del 95%) de 4,83 años. No se observaron diferencias significativas en la condición física entre niños y niñas. Los niños realizaron una actividad física de mayor intensidad y tiempo que las niñas. Además, se encontró una fuerte relación significativa entre los componentes de la condición física y los dominios de la actividad física. Conclusiones: estos hallazgos resaltan la importancia de promover estilos de vida activos desde temprana edad y la necesidad de programas de entrenamiento estructurado para reducir el sedentarismo y mejorar la condición física en esta población.

Background: Adherence to 24-hour movement behavior recommendations, including physical activity (PA), sedentary time, and sleep, is essential for the healthy development of preschool children. Gamified family-based interventions have shown the potential to improve adherence to these guidelines, but evidence of their effectiveness among children is limited. Objective: This study aimed to evaluate the effectiveness of a gamified family-based exercise intervention in promoting adherence to 24-hour movement behavior recommendations among preschool-aged children. Methods: This 12-week study is a single-center, pragmatic randomized controlled trial that included 80 preschool children (56% boys) and their families, who were randomly assigned to either the gamification group (n=40) or the control group (n=40). The “3, 2, 1 Move on Study” incorporates family-oriented physical activities and gamification techniques to increase PA domains, reduce sedentary behavior, and improve sleep patterns. The primary outcome was to increase moderate to vigorous PA (MVPA) by 5 minutes/day, as measured by accelerometer at follow-up. Accelerometer-determined daily time spent (PA domains, sedentary behavior, and sleep), physical fitness (cardiorespiratory, speed-agility, muscular, physical fitness z-score), basic motor competencies (self-movement and object movement), and executive function (memory, cognitive flexibility, and inhibitory control) were also included as secondary outcomes. Results: The 71 participants included in the per-protocol analyses (32 girls, 45%; 39 boys, 55%) had a mean (SD) age of 5.0 (0.5) years. Change in MVPA per day after the intervention (12 weeks) increased in both groups by +25.3 (SD 24.6) minutes/day in the gamification group and +10.0 (SD 31.4) minutes/day in the routine care group, but no significant between-group differences were observed (8.62, 95% CI –5.72 to 22.95 minutes/day, ηp2=.025; P=.23). The analysis of secondary outcomes showed significant between-group mean differences in the change in physical behaviors derived from the accelerometers from baseline to follow-up of 26.44 (95% CI 8.93 to 43.94) minutes/day in favor of light PA (ηp2=.138; P=.01) and 30.88 (95% CI 4.36 to 57.41) minutes/day in favor of total PA, which corresponds to a large effect size (ηp2=.087; P=.02). Likewise, the gamification group substantially increased their score in standing long jump and physical fitness z-score from baseline (P<.05). Conclusions: In the “3, 2, 1 Move on Study,” a gamified intervention showed a modest but relevant increase in MVPA and other domains of 24-hour movement behavior among preschool-aged children. Therefore, gamified family-based interventions may provide a viable alternative to improve adherence to 24-hour movement behavior recommendations.

(BMC, 2023) Legarra Gorgoñón, Gaizka; García Alonso, Yesenia; Ramírez Vélez, Robinson; Erice Echegaray, Blanca; Izquierdo Redín, Mikel; Alonso Martínez, Alicia; Ciencias de la Salud; Osasun Zientziak; Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa; Gobierno de Navarra / Nafarroako Gobernua
Background: Basic motor competencies (BMC) play a vital role in child development and are a primary focus of physical education. However, there is a lack of research on BMC in preschool-aged children, making this study particularly significant. The present study aims to examine the relationship between BMC and physical fitness components in Spanish preschool children. Methods: This cross-sectional study was conducted on 101 children (n = 52 boys, average age of 4.80 years) living in Pamplona, North Spain. Components of physical fitness (handgrip strength, standing long jump, speed-agility, and cardiorespiratory fitness) were assessed using the PREFIT Battery. Overall physical fitness was computed from the four selected fitness components separately for boys and girls. Higher z-scores values in physical fitness indicate better fitness performance. To assess BMC, the MOBAK KG test battery was applied (subscales of object control and self-movement). Sex, age, and body mass index were used as main confounders. Results: After adjustment for confounding factors, the BMC was positively associated with single (z-scores) components and overall physical fitness sum of z-scores (R 2 from 0.178 to 0.469, all P-values < 0.05). Additional percentile scores weakened the associations, but they still remained significant (R 2 from 0.146 to 0.337, all P-values < 0.05). Compared with participants in the lowest tertile, those in the highest tertile of the MOBAK KG sum score, and in both object movement and self-movement test subscales had significantly higher scores in single fitness component (z-scores or percentile) and overall physical fitness sum of z-scores (all P for trend < 0.001). Conclusions: Our results revealed that higher BMC is associated with better physical fitness in Spanish preschool children. The findings emphasize the crucial role that basic motor competence plays in promoting physical activity in preschool children.
