OBJECTIVE
To identify sociodemographic, physical activity, and physical fitness factors associated with flexibility.
METHODS
Cross-sectional study with 909 adolescents (486 girls) aged 14 to 19 years from the city of São José, Santa Catarina, Brazil. To evaluate flexibility, we used the sit and reach test. Sociodemographic and physical activity data were collected by a self-administered questionnaire. We analyzed muscle strength with manual dynamometry. Aerobic fitness was assessed with the modified Canadian aerobic fitness test, and physical activity with a questionnaire. We used multiple linear regression to identify the variables associated with flexibility, with a significance level of 5%.
RESULTS
For each additional centimeter in the girls' levels of flexibility, the boys were 2.94 cm less flexible. In addition, the increment of 0.12 kg/force in muscle strength levels increased the levels of flexibility in 1 cm.
CONCLUSIONS
Lower levels of flexibility were associated with male adolescents and with reduced strength levels.
目的
确定与柔韧性相关的社会人口统计学、身体活动和身体素质因素。
方法
对来自巴西圣卡塔琳娜州圣若泽市的909名14至19岁青少年（486名女孩）进行横断面研究。为评估柔韧性，我们使用了坐位体前屈测试。社会人口统计学和身体活动数据通过自填问卷收集。我们用握力计分析肌肉力量。有氧适能通过改良的加拿大有氧适能测试进行评估，身体活动情况则通过问卷进行调查。我们使用多元线性回归来确定与柔韧性相关的变量，显著性水平为5%。
结果
女孩的柔韧性水平每增加1厘米，男孩的柔韧性就少2.94厘米。此外，肌肉力量水平每增加0.12千克力，柔韧性水平就提高1厘米。
结论
柔韧性水平较低与男性青少年以及力量水平降低有关。
