Body image, nutritional status, abdominal strength, and cardiorespiratory fitness in children and adolescents practicing sports

OBJECTIVE To verify the association between nutritional status, physical fitness, and body image in children and adolescents. METHODS This cross-sectional study included 401 students (236 boys and 165 girls) aged between 8 and 16 years that were regularly enrolled in sports in the local clubs. The nutritional status was evaluated by the body mass index. Students were assessed for satisfaction with body image, abdominal strength resistance, and cardiorespiratory fitness. The variables were assessed on the same day following a standardized order. In order to verify relationships between variables, the chi-square test was used. Afterwards, the binary logistic regression was applied to identify the magnitude of the associations, considering p<0.05 as significant. RESULTS Association was found between body image and body mass index (p=0.001), abdominal strength resistance (p=0.005) and cardiorespiratory fitness (p=0.001). The Odds Ratio for presenting the body image insatisfaction for those who have not achieved the expected values for the health criteria in abdominal strength resistance and cardiorespiratory fitness were 2.14 and 2.42 times respectively, and for those with overweight and obesity, 2.87 times. CONCLUSIONS Insatisfaction with body image is associated with body mass index and also with physical fitness, abdominal strength resistance, and cardiorespiratory fitness variables.OBJETIVO: Verificar se ha associacao entre estado nutricional, nivel de aptidao fisica e imagem corporal em criancas e adolescentes. METODOS: Participaram deste estudo transversal 401 estudantes (236 meninos e 165 meninas) com idades entre 8 e 16 anos, praticantes de esportes nos clubes locais. Para o estado nutricional calculou-se o indice de massa corporea. Foram avaliadas a satisfacao com a imagem corporal, a forca de resistencia abdominal e a aptidao cardiorrespiratoria. As variaveis foram analisadas no mesmo dia, seguindo ordem padronizada. Para verificar as associacoes entre as variaveis foi utilizado o teste do qui-quadrado. Posteriormente, a regressao logistica binaria foi aplicada para identificar a magnitude das associacoes, considerando-se significante p<0,05. RESULTADOS: Foi constatada associacao entre imagem corporal e indice de massa corporea (p=0,001), forca de resistencia abdominal (p=0,005) e aptidao cardiorrespiratoria (p=0,001). A razao de chances para os participantes que nao atingiram os valores esperados para os criterios de saude na forca de resistencia abdominal e na aptidao cardiorrespiratoria de apresentarem insatisfacao com a imagem corporal foi de 2,14 e 2,42 vezes, respectivamente, e para aqueles com sobrepeso e obesidade, de 2,87 vezes. CONCLUSOES: A insatisfacao com a imagem corporal esta associada ao indice de massa corporea e tambem as variaveis de aptidao fisica, forca de resistencia abdominal e aptidao cardiorrespiratoria.

PHYSICAL FITNESS AND SPORTS ACTIVITIES FOR CHILDREN AND ADOLESCENTS

Introduccion: Una de las funciones de la educacion fisica en la escuela - la promocion de habitos saludables - no se ha cumplido. Delante de eso, la opcion por la participacion de ninos y jovenes en programas de deportes como estrategia para auxiliar en la mejora de los componentes de la aptitud fisica viene siendo ampliamente utilizada. Sin embargo, todavia no esta claro que tipo de deportes pueden ofrecer beneficios de una mayor magnitud. Objetivo: El objetivo del estudio fue identificar la asociacion entre los componentes de aptitud fisica orientados a la salud y los deportes individuales y colectivos en los ninos y adolescentes. Metodo: Para eso, participaron del estudio 401 sujetos de edades comprendidas entre ocho y 16 anos. Los componentes de la aptitud fisica se evaluaron mediante la bateria de pruebas PROESP - 2007. Para el analisis de datos se utilizo la prueba de chi-cuadrado y regresion logistica binaria para identificar asociaciones y sus magnitudes. Resultados: Los sujetos que practican deportes individuales mostraron 1,93 y 2,32 veces mas probabilidades de alcanzar los valores esperados de aptitud fisica para el indice de masa corporal y flexibilidad. Por otro lado, los practicantes de modalidades colectivas presentaron 75% mas de probabilidad de alcanzar los criterios de salud de la capacidad fisica para fuerza de miembros superiores. Conclusion: Por lo tanto, se puede concluir que los diversos componentes de la aptitud fisica orientada a la salud estan asociados con los deportes en los ninos y adolescentes.introduction: one of the roles of physical education in school – promoting healthy habits – is not being fulfilled. therefore, participation of children and young people in sports programs, as a strategy to help improve different components of physical fitness, has been widely used. But it is still not clear what types of sports can offer the greatest benefits. objective: to identify the association between different components of physical fitness focused on health, and individual and collective sports in children and adolescents. Methods: 401 subjects aged between eight and 16 years participated in the study. the components of physical fitness were assessed using the ProesP – 2007 battery of tests. for the data analysis, we used the chi-square test and binary logistic regression to identify associations and their magnitudes. results: the subjects who practiced individual sports were 1.93 and 2.32 times more likely to achieve expected values of physical fitness for body mass index and flexibility. on the other hand, those who played collective sports were 75% more likely to achieve the health criteria of physical capacity for upper limb strength. conclusion: We conclude that the various components of health-oriented physical fitness are associated with sports in children and adolescents.
