    COVID-19 causes cardiovascular and lung problems that can be aggravated by confinement, but the practice of physical activity (PA) could lessen these effects. The objective of this study was to evaluate the association of maximum oxygen consumption (VO2max) with vaccination and PCR tests in apparently healthy Chilean adults. An observational and cross-sectional study was performed, in which 557 people from south-central Chile participated, who answered an online questionnaire on the control of COVID-19, demographic data, lifestyles, and diagnosis of non-communicable diseases. VO2max was estimated with an abbreviated method. With respect to the unvaccinated, those who received the first (OR:0.52 [CI:0.29;0.95], p = 0.019) and second vaccine (OR:0.33 [CI:0.18;0.59], p = 0.0001) were less likely to have an increased . VO2max. The first vaccine was inversely associ- ated with . VO2max (mL/kg/min) (Ī²:āˆ’1.68 [CI:āˆ’3.06; āˆ’0.3], p = 0.017), adjusted for BMI (Ī²:āˆ’1.37 [CI:āˆ’2.71; āˆ’0.03], p = 0.044) and by demographic variables (Ī²:āˆ’1.82 [CI:āˆ’3.18; āˆ’0.46], p = 0.009); similarly occur for the second vaccine (Ī²: between āˆ’2.54 and āˆ’3.44, p < 0.001) on models with and without adjustment. Having taken a PCR test was not significantly associated with VO2max (mL/kg/min). It is concluded that vaccination significantly decreased . VO2max, although it did not indicate cause and effect. There is little evidence of this interaction, although the results suggest an association, since V O2max could prevent and attenuate the contagion symptoms and effects.

    El estudio tuvo como objetivo analizar las diferencias en el desarrollo infantil en las dimensiones de motricidad, lenguaje, cogniciĆ³n y estado socioemocional en escolares de cinco y seis aƱos pertenecientes a una escuela rural y otra urbana de la regiĆ³n del BiobĆ­o en Chile. El estudio fue observacional de corte transversal, con caracterĆ­sticas descriptivas y analĆ­ticas. La muestra fue compuesta por 28 escolares de ambos sexos, distribuidos en siete niƱas y siete niƱos de una zona rural (5.7Ā±0.5 aƱos) y siete niƱas y siete niƱos de una zona urbana (5.6Ā±0.6 aƱos), seleccionada de forma no probabilĆ­stica por conveniencia. Se evaluĆ³ el desarrollo infantil por medio del Test de Aprendizaje del Desarrollo Infantil (TADI). Los resultados muestran que existen diferencias significativas en los puntajes promedio de las dimensiones motriz y cognitiva (pĖ‚0.05), con mejores resultados en los escolares de la zona rural. No hubo diferencias significativas en las dimensiones de lenguaje y estado socioemocional (pĖƒ0.05), ademĆ”s se evidencia una relaciĆ³n positiva directa entre las dimensiones motriz y socioemocional para la zona urbana (pĖ‚0.05). Se concluye que existen diferencias significativas en el desarrollo infantil entre los escolares pertenecientes a la zona rural y a la zona urbana, especĆ­ficamente en las dimensiones motriz y cognitiva, con mejores resultados para los escolares de la zona rural.
