    Argentina´s global matrix 4.0 report card results on physical activity for children and adolescents
    (Human Kinetic Journal, 2024-11-12) Lobo, Pablo; Holgado, Micaela; López, Laura; Baigún, Valeria; De Roia, Gabriela
    The objective of the Argentine Global Matrix 4.0 Report Card was to synthesize the available national evidence on topics related to physical activity and health of children and adolescents and, based on that evidence, to assign a grade to some related indicators. Methods: The Report Card working group reviewed and compiled the best available evidence on the indicators developed by Active Healthy Kids Global Alliance. Each of the 12 grades (for 10 core and 2 optional indicators) were based on the percentage of children and adolescents meeting a benchmark established in the Global Matrix grading rubric: These grades could range from A+ (best) to F (worst), or an incomplete was assigned when evidence was insufficient or inadequate for grading. The grades were subsequently reviewed and harmonized by 2 independent Active Healthy Kids Global Alliance reviewers. Results: Overall Physical Activity, Sedentary Behavior, and Government, all received a grade of D+. Organized Sport and Physical Activity and Community and Environment each received a grade of C−. Obesity received a grade of C+. Active Play, Active Transportation, Physical Fitness, Family and Peers, School, and Sleep were graded as incomplete. Conclusions: Only half of the indicators were able to be graded, as the other half were inconclusive due to lack of evidence. This leaves a gap and thus a challenge at the national level to improve research, surveillance systems, and policies to promote physical activity during childhood and adolescence.

    In Argentina, evidence on physical activity is insufficient, so half of the indicators couldn´t be graded
    (Universidad de Flores, 2022) Lobo, Pablo; Holgado, Micaela; López, Laura; Baigún, Valeria; De Roia, Gabriela
    Based on the Global Matrix 4.0 initiative, Argentina's development of its first Report Card required a comprehensive review of nation-wide available evidence on the topic.

    Physical activity during pregnancy and childhood obesity : systematic review and meta-analysis
    (Multidisciplinary Digital Publishing Institute, 2024-06-22) Barakat, Rubén; Silva José, Cristina; Sánchez Polan, Miguel; Zhang, Dingfeng; Lobo, Pablo; De Roia, Gabriela; Montejo, Rocío
    The repercussions of childhood overweight and obesity are multifaceted, extending beyond the realm of physiology and giving rise to psychological and emotional disturbances in affected children. The precise effects of gestational physical activity (PA) on parameters related to childhood overweight and obesity remain inadequately understood. The aim of this study (Registration CRD42022372490) was to evaluate the literature regarding the influence of PA during pregnancy on the risk of childhood overweight and obesity. Materials and Methods: Only randomized controlled trials (RCTs) were considered for inclusion. Determinant parameters of childhood obesity were analyzed. A total of 30 studies involving 16,137 pregnant women were examined. Five meta-analyses about the effects of PA during pregnancy on determinants of childhood overweight and obesity were conducted. Results: Although favorable trends were observed, Meta-Analyses showed no statistical differences in the effects of PA on weight at birth (Z = 0.03, p = 0.97), Ponderal Index at birth (Z = 0.64, p = 0.52), Macrosomia and Large for Gestational Age at birth (Z = 0.93, p = 0.35), children’s BMI (Z = 0.78, p = 0.44), weight (Z = 0.50, p = 0.62), and skinfold thicknesses (Z = 0.45, p = 0.65). Conclusions: The engagement in physical activity during pregnancy exhibits a favorable trend in parameters associated with childhood overweight and obesity while presenting no adverse effects on such outcomes.

    Punto de quiebre del doble producto como indicador de transición metabólica durante el ejercicio en pacientes coronarios
    (Federación Argentina de Cardiología, 2016) Resnik, Miguel; De Roia, Gabriela; Lobo, Pablo; Peralta, Liliana; Saccone, Flavia; Puga, Leopoldo; Taurozzi, Sergio; Moreno, Gustavo
    El umbral anaeróbico ha sido utilizado como un buen indicador de capacidad funcional y de implicancias pronósticas en pacientes cardíacos. El objetivo fue evaluar un método no invasivo como el punto de quiebre del doble producto (PQDP) durante el ejercicio, punto en el cual se produjo un aumento claro y sostenido de la pendiente de doble producto (DP) durante la prueba de esfuerzo incremental. DP= frecuencia cardiaca (FC) x presión arterial sistólica (PAS), que podría ser aplicado para el entrenamiento físico y de información pronóstica en pacientes con enfermedad coronaria (EC). Material y métodos. Se evaluaron 33 hombres y 9 mujeres de 64,8 ± 7,6 años con EC documentada, clínicamente estables con tratamiento médico y en ritmo sinusal. Todos realizaron una PEG en cinta deslizante. El ejercicio consistió en un período inicial de entrada en calor (1 km/h) con cargas crecientes por etapa de 0,4 km/h cada minuto hasta el límite de tolerancia del sujeto. El consumo de oxígeno (VO2) se midió con un sistema portátil (COSMED), la FC con un ECG de 12 derivaciones y la presión arterial por esfigmomanometría en cada etapa. El DP vs VO 2 fue sometido a 3 evaluadores independientes para la determinación visual del VT1 y PQDP. El test de Student se utilizó para comparar velocidad (km/h) en VT1 y PQDP y el coeficiente de correlación de Pearson entre ambos parámetros (p<0,05). Resultados. Los pacientes no tuvieron síntomas. Se determinó el VT1 y PQDP en todos ellos. La velocidad del PQDP fue de 2,6 ± 0,5 km/h y la velocidad en VT1 2,6 ± 0, 6 km/h, sin diferencias significativas entre ambos. Encontramos una correlación positiva comparando VT1 vs PQDP (r2=0,6). Conclusiones. Se pudo medir el PQDP en pacientes coronarios con una buena correlación positiva con VT1
