Resumo Os objetivos do presente estudo foram testar possíveis diferenças entre os sexos quanto ao envolvimento em brigas nos últimos 12 meses e analisar a associação desse comportamento com fatores sociodemográficos e a participação em atividade física em rapazes e moças. Foram avaliados 6529 estudantes (15 a 19 anos) do ensino médio da rede pública estadual do estado de Santa Catarina. Dados sociodemográficos, o envolvimento em brigas e os tipos de atividades físicas foram investigados por meio de questionário previamente testado. Utilizou-se de análises de regressão logística binária bruta e ajustada. Os rapazes (36,9%) relataram maior envolvimento em brigas em relação às moças (26,0%, p<0,05). Rapazes que residiam em área urbana (OR:1,45) e não moravam com a família (OR: 2,22), assim como moças que estudavam no período noturno (OR: 1,26) apresentaram maiores chances de envolverem-se em brigas. Adolescentes de 17 a 19 anos possuíam chances reduzidas de envolverem-se em brigas (ORRapazes:0,66; ORMoças:0,80) comparados aos de 15 e 16 anos. A prática de atividades coletivas nos rapazes (OR: 1,56) e a prática combinada de atividades coletivas e individuais em rapazes (OR: 1,91) e moças (OR: 1,36) foram associadas ao envolvimento em brigas. Conclui-se que rapazes foram mais propensos a se envolverem em brigas, principalmente os mais novos, aqueles que não moravam com a família e que residiam em área urbana. Em ambos os sexos, o envolvimento em brigas foi maior entre os praticantes de atividades físicas coletivas.

Abstract The aims of the present study were to evaluate possible gender differences in the prevalence of physical aggression among adolescents, and to examine the association between sociodemographic factors and physical activity participation with physical aggression in boys and girls. The sample was composed of 6,529 high school students (aged 15-19 years) from public schools of the state of Santa Catarina. A questionnaire was applied to collect data regarding sociodemographic factors, involvement in physical aggressions and types of physical activity. Crude and adjusted binary logistic regression models were performed. Boys reported more involvement in physical aggression episodes (36.9%) compared to girls (26.0%, p<0.05). Boys who lived in urban areas (OR: 1.45) and did not live with the family (OR: 2.22), as well as girls enrolled in the night shift were more likely to engage in fights (OR: 1.26). Adolescents aged 17-19 years had reduced chances of getting involved in fights (ORBoys: 0.66; ORGirls: 0.80) compared to younger ones. The practice of team sports among boys (OR: 1.56) and the combined practice of team sports and individual physical activities among boys (OR: 1.91) and girls (OR: 1.36) were associated with physical aggressions. It was concluded that boys were more likely to engage in fights, mainly younger boys, who did not live with family and lived in urban areas. In boys and girls, the involvement in physical aggression was greater among those who are engaged in team sports.

Abstract Aims This study aimed to identify Brazilian wheelchair tennis athletes' quality of life and to compare the perception scores between competitive and elite athletes. Methods Participants were wheelchair tennis athletes (N = 31) from Brazil (males = 25, females = 6) divided into two groups: competitive and elite. Data was collected using the Brazilian version of the WHOQOL-Bref. The WHOQOL-Bref asks two general questions, and is thereafter divided into four main domains: 1) physical, psychological, social, and environment, which give us an understanding of their overall quality of life perception. Results The results showed that overall, 29 out of the 31 athletes perceived their quality of life positively, regardless of the competitive level. However, statistically higher perceptions were found in the physical domain and the total score of quality of life of the elite group. Conclusion The findings of this study suggest that even though participation in high-performance adapted sports may offer a stressful and exhausting environment, elite wheelchair tennis athletes from Brazil perceive themselves as having a better QoL than competitive athletes.
