RESUMO -A relação entre atividade física e insatisfação corporal é pouco explorada na literatura. Foi examinada a insatisfação corporal em relação com o nível de atividade física em estudantes adolescentes de escolas públicas de Florianópolis. A amostra foi de 242 estudantes, 109 meninos (14,6±2,8 anos) e 133 meninas (14,3±3 anos). Os instrumentos utilizados foram: questionário de atividades físicas habituais e escala de percepção de silhueta corporal. Quarenta e três por cento dos meninos e 29,4% das meninas são pouco ativos. Sessenta e nove por cento dos meninos e 76,7% das meninas estão insatisfeitos com sua silhueta corporal. Os meninos demonstram uma tendência em aumentar e diminuir sua silhueta, enquanto as meninas demonstram querer diminuir. Não foi encontrada relação entre satisfação com a silhueta corporal e nível de atividade física habitual. Investigar a relação entre atividade física e insatisfação corporal pode auxiliar em pesquisas futuras que verifi quem intervenções terapêuticas com atividade física no tratamento da insatisfação corporal.Palavras chave: insatisfação corporal; atividade física; adolescentes; silhueta corporal.
Body Dissatisfaction and Physical Activity in Adolescents from FlorianópolisContinental Region ABSTRACT -The relationship between physical activity and body dissatisfaction is little explored in literature. It was examined the body dissatisfaction and physical activity relationship among adolescents students of public schools from Florianópolis, Brazil. The sample was composed by 242 students, 109 boys (14,6±2,8 years) and 138 girls (14,3±3 years). The instruments used were a habitual physical activities questionnaire and a body silhouette's scale. Forty three per cent of girls and 29,4% of boys are insuffi ciently active. Sixty nine per cent of the boys and 76,7% of the girls are unsatisfi ed with their body silhouette. Boys demonstrate a tendency of both increase and decrease their body silhouette, while girls demonstrate a tendency to decrease their body silhouette. No association was found between satisfaction with body silhoutte and habitual physical activity status. To investigate the relationship between physical activity and body dissatisfaction can be useful for future research that could be verifi ed in the therapeutical interventions with physical activity for the body dissatisfaction treatment.
The MarkSim climate data generator is designed to have global validity in scales of up to five degrees. Thus, the objective of this study was to evaluate the performance of the MarkSim-HadGEM2-ES and MarkSim-MIROC5 models to estimate average rainfall in the last agricultural frontier of the savannah in the north and north-east regions of Brazil. For this purpose, the simulated data were compared with those observed and recorded by the National Institute of Meteorology, being evaluated by statistical measures of correlation, bias and performance. The results revealed high bias and relative error, with unsatisfactory performance in the micro regional and regional scales. Calibration by means of regression improved performance and showed that in order to reproduce the current climate and make reliable projections in these spatial scales possible, there is a need to correct the systemic errors of these models.
The climate models adopted by the Intergovernmental Panel on Climate Change are capable of reproducing the current climate well on a continental scale, but need to be validated on a smaller scale. The objective of this study was to evaluate the performance of the regional models MarkSim-HadGEM2-ES and MarkSim-MIROC5 to estimate average temperatures in the last frontier of agricultural expansion of the Brazilian savannah. For this purpose, the data generated by the models were compared with those recorded by the National Institute of Meteorology and evaluated by statistical measures of correlation, bias and performance. The results revealed low bias and very good agreement, but high relative error and unsatisfactory performance in micro-regional and regional scales. Thus, the data generated by these models need correction to reproduce the current climate and enable reliable projections on these spatial scales.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
