These policies will only be successful if they are implemented well, are continuously assessed, and are flexible. Overall result found the positive and significant influence of Brazil's public health policies on physical activity promotion in the urban areas. Brazil's dedication to encouraging physical exercise indicates the global recognition of the significance of preventative health measures. Sustained endeavors towards this end might foster a more robust and engaged urban populace in Brazil.
