Media influence may lead adolescents to internalize patterns of physical beauty, resulting in dissatisfaction with their own bodies when they are unable to match up to these patterns. In the constant search for an ‘ideal body’, adolescents may begin to develop risk behaviors for the development of eating disorders (ED). The object of this study was to analyze the influence of the mass media on body dissatisfaction (BD) and on ED in adolescents, comparing genders. We also analyzed the influence of BD on the risk of developing unsuitable eating behaviors, with risk of ED, comparing genders. A cross-sectional study was carried out with 1011 adolescents: 527 girls and 484 boys. The BMI of each adolescent was determined, and the instruments EAT-26, Sociocultural Attitudes towards Appearance Questionnaire-3 (SATAQ-3), and body shape questionnaire (BSQ), were applied. For statistical analysis, we used Student’s t-test, the chi-square test, Pearson’s correlation test, the odds ratio, and hierarchical multiple linear regression. The influence of the mass media is associated with a greater probability of adolescents presenting BD. An increase in BD is associated with an increased risk of developing ED in adolescents of both genders but is greater in girls than in boys. Furthermore, the influence of the MM and BMI are predictors of BD in both genders; and BD is a predictor of ED risk in both girls and boys.

Rhythmic gymnastics (RG) athletes need high-performance training since a high degree of precision is required in their exercises. Plyometric training (PT) has been used to improve athletes' neuromuscular function, explosive performance and strength in competition. The object of this study was to assess the efficiency of PT in improving the performance of RG athletes in the juvenile and adult categories over 12 months, by incorporating PT into two training macrocycles. Thirty athletes were selected; they were divided randomly into a control group (CG) and an experimental group (EG) of 15 athletes each. Two 6-month training macrocycles were drawn up for the EG in which they maintained normal training with the addition of PT. The CG maintained its normal training. Three tests were used for the assessment: vertical jump, horizontal jump and agility, assessed at 5 different moments. After 12 months it was observed an improvement in test performance in both groups, with a more significant improvement in the EG when compared to the CG. The addition of PT to normal training improved the performance of athletes by developing greater power in the lower limbs, increasing their capacity in vertical jump, horizontal jump and agility.

Background: The present study investigated the influence of body dissatisfaction (BD) on the self-esteem of Brazilian adolescents. Methods: A cross-sectional study was carried out with 1011 students at public and private schools in the city of Fortaleza, Brazil. The body shape questionnaire and the Rosenberg self-esteem scale were applied. Chi-square test, Student’s t-test, Pearson’s correlation, the odds ratio and binary logistic regression were used. Results: The rate of low self-esteem was 33.8% in the adolescents; 27.8% of the adolescents presented some degree of BD, with severe BD in 5.8%. A significant low negative correlation was found between self-esteem and BD in all the adolescents. In the Odds Ratio analysis, it was observed that the odds of having low self-esteem increased in adolescents with BD as compared to adolescents without BD, being 3.85 times higher in females (CI 95%, 2.12–6.99), 2.83 times higher in males (CI 95%, 1.22–6.58), 5.79 times higher in adolescents attending public schools (CI 95% 2.06–16.26), and 2.96 times higher in adolescents attending private schools (CI 95%, 1.79–4.88). Conclusions: Low self-esteem affected one-third of the adolescents, both male and female. BD and education in public schools are predictor variables of low self-esteem in adolescents.

A preocupação com a aparência física é algo indispensável ao ser humano e é cada vez mais preponderante em nossa sociedade que, através de diversos meios, evidencia corpos esteticamente perfeitos. No decorrer dos últimos anos, houve uma crescente preocupação com a imagem corporal (IC). Como a maioria da população não se encaixa nos padrões que a mídia impõe, podem surgir distorções da IC. A imagem corporal configura-se como a figura mental que temos do nosso corpo, juntamente de como sentimos, de como queremos que ele seja. Objetivo: o objetivo da pesquisa foi realizar uma revisão de literatura sobre imagem corporal, identificando suas causas e implicações nos adolescentes. Método: a pesquisa realizada caracteriza-se como uma revisão de literatura. A busca dos artigos ocorreu nos meses de setembro a novembro de 2015, nas bases de dados eletrônicas Scielo, Medline, Pubmed, Scopus e Lilacs. Resultados: foram encontrados 56 artigos, conforme os requisitos da pesquisa; foram utilizados 23 artigos para revisão. Considerações finais: a influência das relações sociais, na transformação da IC, exerce um papel fundamental na atual sociedade. O fator simbólico do corpo tornou-se fator fundamental de inserção social, especialmente entre os jovens. INTRODUÇÃOA Imagem Corporal (IC) é a figuração do corpo formada em nossa mente, ou seja, o modo pelo qual o corpo se apresenta para nós.1 Ainda assim a autoimagem conceitua-se na figura mental que temos das partes do nosso corpo, no formato e sua medida, juntamente com sentimentos de desejo de como queremos que elas sejam. 2A imagem corporal reúne os fatores físicos, emocionais e mentais em cada ser humano e a saúde mental só é conseguida quando a percepção do corpo chega

RESUMOO estilo de vida dos estudantes universitários envolvem comportamentos que podem comprometer tanto a saúde como a qualidade de vida (QV). Objetivo: verificar a percepção da QV, níveis de atividade física e variáveis antropométricas em graduandos do curso de Educação Física em uma instituição privado na cidade de Fortaleza, Ceará. Método: foram selecionados 122 acadêmicos de ambos os gêneros, este valor referente a 31% do total de matriculados em 2014.2, noite. Utilizou-se como métodos WHOQOL-abreviado para QV, o Questionário Internacional de Atividades Físicas--curto, para os níveis de atividade física e a relação cintura/pescoço e cintura/quadril para as variáveis antropométricas. Resultados: as médias do questionário WHOQOL-abreviado atingiram posição satisfatória, com média para o domínio físico= 27,3±3,6, psicoló-gico= 23,4±2,9 e as relações sociais de 11,8±2,1, já o domínio meio ambiente demostrou perfil mais baixo, com média de 25,8±4,4. O nível de atividades físicas apresentou 6 alunos (4%) como sedentários, 60 (49%) como ativos e 56 (45%) como muito ativos. As medidas antropométricas analisadas não demostraram dados significantes (p=0,91). ABSTRACTThe lifestyle of college students involve behaviors that can compromise both health and quality of life (QOL).
