Motivos da prática de dança de salão nas aulas de educação física escolar

O estudo de corte transversal analisou os motivos da prática da dança de salão nas aulas de Educação Física escolar de escolas particulares, relacionando-os com o gênero, seu tempo de prática e participação em eventos de dança de salão. Obteve-se uma amostra de 279 alunos com idade de 15,5 ± 1,0 anos, matriculados nas aulas de dança de salão como Educação Física escolar. Aplicou-se o questionário de motivação para as atividades desportivas - QMAD, adaptado de SERPA e FRIAS (1990) e SERPA (1991). Analisou-se os dados através da estatística descritiva e inferencial, com nível de significância de 95%. Foram encontradas associações significativas entre os motivos e gêneros (r = 0,285; - 0,172); tempo de prática (r = 0,174) e frequência em eventos (r = 0,122; - 0,156). A dança de salão oferece em sua prática uma ferramenta de inúmeras possibilidades, onde cada um de seus praticantes procura preencher as suas próprias necessidades. De acordo com os resultados levantados percebe-se que os alunos estão motivados com a prática de dança de salão na escola havendo diferenças entre o gênero, o tempo de prática e a frequência nos eventos. Diante disto sugere-se a criação de propostas metodológicas condizentes com os principais motivos dos alunos nas aulas de dança de salão dentro do ambiente da Educação Física escolar.The transversal study analyzed the reasons for the practice of ballroom dance in the curricular physical activity in private schools, relating them to the gender, its practice time and participation in ballroom dance events. The study was composed of 279 students at the age of 15.5 ± 1.0, enrolled in ballroom dance as part of regular physical education. The Sport Motivation Questionnaire - SMQ, adapted from SERPA and FRIAS (1990), SERPA (1992) was used. The descriptive and inferential statistics were used with a 95% significance level. Significant associations were found between reasons and the genders (r = 0.285; - 0.172); practice time (r = 0.174) and event frequency (r = 0.122; - 0.156). The ballroom dance offers in its practice a tool of countless possibilities, in which each of its participants search to fulfil their own necessities. According to the risen results it is noticeable that students are motivated with the practice of ballroom dance in schools presenting differences in gender, practice time, and event attendance. Then, it is suggested the creation of methodological proposals coherent to the main goals of the students of ballroom dance within the regular physical education environment in schools

Obesity, inflammation, and insulin resistance

White adipose tissue (WAT) is considered an endocrine organ. When present in excess, WAT can influence metabolism via biologically active molecules. Following unregulated production of such molecules, adipose tissue dysfunction results, contributing to complications associated with obesity. Previous studies have implicated pro- and anti-inflammatory substances in the regulation of inflammatory response and in the development of insulin resistance. In obese individuals, pro-inflammatory molecules produced by adipose tissue contribute to the development of insulin resistance and increased risk of cardiovascular disease. On the other hand, the molecules with anti-inflammatory action, that have been associated with the improvement of insulin sensitivity, have your decreased production. Imbalance of these substances contributes significantly to metabolic disorders found in obese individuals. The current review aims to provide updated information regarding the activity of biomolecules produced by WAT
