Lack of physical activity is a global public health problem causing not only morbidity and premature mortality, but it is also a major economic burden worldwide. One of the cornerstones of a physically active lifestyle is Motor Competence (MC). MC is a complex biocultural attribute and therefore, its study requires a multi-sectoral, multi-, inter- and transdisciplinary approach. MC is a growing area of research, especially in children and adolescents due to its positive association with a plethora of health and developmental outcomes. Many questions, however, remain to be answered in this field of research, with regard to: (i) Health and Developmental-related Associations of MC; (ii) Assessment of MC; (iii) Prevalence and Trends of MC; (iv) Correlates and Determinants of MC; (v) MC Interventions, and (vi) Translating MC Research into Practice and Policy. This paper presents a narrative review of the literature, summarizing current knowledge, identifying key research gaps and presenting questions for future investigation on MC in children and adolescents. This is a collaborative effort from the International Motor Competence Network (IMCNetwork) a network of academics and researchers aiming to promote international collaborative research and knowledge translation in the expansive field of MC. The knowledge and deliverables generated by addressing and answering the aforementioned research questions on MC presented in this review have the potential to shape the ways in which researchers and practitioners promote MC and physical activity in children and adolescents across the world.
O uso de espécies espontâneas da Caatinga como adubos verdes é uma técnica de manejo alternativa para a produção de hortaliças no Nordeste do Brasil, mas ainda escassas são as informações. O presente trabalho foi realizado de outubro a dezembro de 2009 em Mossoró-RN com o objetivo de avaliar o efeito de três espécies espontâneas da Caatinga em diferentes doses de biomassa nos atributos microbiológicos do solo e na produtividade do rabanete. O delineamento experimental foi em blocos casualizados com três repetições, sendo os tratamentos compostos de três espécies da Caatinga [jitirana (Merremia aegyptia); mata-pasto (Senna uniflora) e flor-de-seda (Calotropis procera)] utilizadas em cinco doses de massa seca (5,4; 8,8; 12,2; 15,6 e 21,0 t ha-1). As características microbiológicas avaliadas no solo foram o número de unidades formadoras de colônia (UFC) de actinomicetos, fungos e bactérias e no rabanete foram as produtividades total e comercial, massa seca de raízes, massa seca da parte aérea e percentagens de raízes comercial e refugo. O crescimento dos microorganismos no solo não foi influenciado pelas espécies estudadas, mas houve aumento no número de UFC de microrganismos com as doses aplicadas (1,025 x 10(4) para actinomicetos; 7,995 x 10² para fungos e 7,841 x 10(6) para bactérias). As maiores produtividades total e comercial e massa seca da parte aérea do rabanete foram obtidas com 21,0 t ha-1 de biomassa de jitirana. As maiores percentagens de raízes comercial e refugo do rabanete foram registradas nas espécies jitirana e mata-pasto. As percentagens máxima de raízes comercial e mínima de raízes refugo foram obtidas com a incorporação de 21,0 t ha-1 de biomassa dos adubos verdes.
