Introdução: O equilíbrio dinâmico é um componente essencial para o desempenho físico e a prevenção de lesões, especialmente em jovens adultos ativos. Fatores como sexo, IMC e nível de AF influenciam significativamente o desempenho no equilíbrio, o que pode afetar o risco de lesões. Estudos anteriores destacaram diferenças sexuais e o impacto da AF no equilíbrio. No entanto, as relações entre esses fatores e suas influências combinadas sobre o equilíbrio ainda não são completamente compreendidas.
Objetivos: Caracterizar o equilíbrio dinâmico em jovens adultos através do teste de equilíbrio Y, avaliando diferenças entre sexo, o índice de massa corporal, os níveis de atividade física, a assimetria de desempenho e o risco de lesão.
Métodos: A amostra foi constituída por 40 jovens adultos saudáveis (25 homens e 15 mulheres), com idades entre 18 e 39 anos. caracterizados por sexo, IMC e nível de AF. O equilíbrio dinâmico foi avaliado utilizando o Teste de Equilíbrio Y (YBT). Foi efetuada a comparação de desempenho entre diferentes grupos de acordo com as variáveis estudadas (sexo, IMC, nível de AF) e avaliação de assimetrias de desempenho. As análises estatísticas foram realizadas no IBM SPSS Statistics (29.0.2.0), com testes de normalidade de Shapiro-Wilk e homogeneidade de Levene. A significância das diferenças foi feita pelo teste t, o d de Cohen foi calculado para avaliar o tamanho do efeito das diferenças entre os sexos e ANOVA one-way foram utilizadas para comparar grupos. Correlações entre variáveis foram determinadas pelo teste de Pearson, com nível de significância de p ≤ 0,05 e intervalos de confiança (IC) de 95%.
Resultados: Não foram encontradas diferenças estatisticamente significativas entre sexo no equilíbrio dinâmico. As análises revelaram uma correlação positiva entre o desempenho do Teste Y e o nível de AF também não foi significativa na maioria das direções, exceto para a assimetria relativa anterior, que apresentou uma correlação positiva significativa (r=0,492, p=0,011). A correlação entre assimetria de desempenho e IMC, apresentou uma correlação significativa apenas na direção posterolateral, indicando que indivíduos com IMC mais elevado apresentaram maior assimetria nessa direção. Relativamente as assimetrias associadas ao risco de lesão nas três direções, a prevalência de risco na direção posteromedial foi de 30,3% e na direção anterior foi de 12,1%.

Conclusão: Pode conclui-se que, não se verificaram diferença estatisticamente significas entre sexos, no equilíbrio dinâmico. Observou-se uma correlação positiva entre o IMC e assimetria na posição postelateral, os sujeitos com valores superiores de IMC apresentam maiores assimetria de desempenho. Na correlação do nível de intensidade de AF com a assimetria de desempenho, não foram encontradas diferenças estaticamente significativas, porém observou-se diferenças nos seus valores médios. No que diz respeito às assimetrias de desempenho associadas ao risco de lesão, a maior percentagem de prevalência de risco verificou-se na direção posteromedial.
Introduction: Dynamic balance is an essential component of physical performance and injury prevention, especially in active young adults. Factors such as sex, BMI, and PA level significantly influence balance performance, which may affect injury risk. Previous studies have highlighted sex differences and the impact of PA on balance. However, the relationships between these factors and their combined influences on balance are not yet fully understood. Objectives: To characterize dynamic balance in young adults using the Y-Balance Test, assessing differences between sex, body mass index, physical activity levels, performance asymmetry, and injury risk. Methods: The sample consisted of 40 healthy young adults (25 men and 15 women), aged 18–39 years, characterized by sex, BMI, and PA level. Dynamic balance was assessed using the Y-Balance Test (YBT). Performance comparisons were performed between different groups according to the variables studied (gender, BMI, PA level) and performance asymmetries were assessed. Statistical analyses were performed using IBM SPSS Statistics (29.0.2.0), with Shapiro-Wilk normality and Levene homogeneity tests. The significance of differences was assessed using the t-test, Cohen's d was calculated to assess the effect size of differences between genders, and one-way ANOVA was used to compare groups. Correlations between variables were determined using Pearson's test, with a significance level of p ≤ 0.05 and 95% confidence intervals (CI). Results: No statistically significant differences were found between genders in dynamic balance. The analyses revealed a positive correlation between Y-Test performance and PA level, which was also not significant in most directions, except for the anterior relative asymmetry, which showed a significant positive correlation (r=0.492, p=0.011). The correlation between performance asymmetry and BMI showed a significant correlation only in the posterolateral direction, indicating that individuals with higher BMI had greater asymmetry in this direction. Regarding the asymmetries associated with the risk of injury in the three directions, the prevalence of risk in the posteromedial direction was 30.3% and in the anterior direction it was 12.1%. 11 Conclusion: It can be concluded that there were no statistically significant differences between sexes in dynamic balance. A positive correlation was observed between BMI and asymmetry in the posterolateral position, with subjects with higher BMI values presenting greater performance asymmetry. In the correlation between the level of PA intensity and performance asymmetry, no statistically significant differences were found, but differences were observed in their mean values. Regarding the performance asymmetries associated with the risk of injury, the highest percentage of risk prevalence was found in the posteromedial direction.
