To examine the link between adherence to 24-h movement guidelines (isolated and combined) and muscular strength, cardiorespiratory fitness, and obesity indicators in Brazilian adolescents.
Data from 980 adolescents (14-19 years) in Florianópolis, Brazil, were analyzed. The dependent variables were body mass index (BMI), body fat, handgrip strength (HGS), maximal oxygen consumption ( O). The independent variables were physical activity (PA, IPAQ), screen time (ST), sleep (bedtime, wake-up time). Compliance was calculated for each behavior and combinations. Multiple linear regression models were employed.
Overall compliance: 4.1% (boys), 4.9% (girls). Positive associations were found between PA adherence and HGS/ O in both sexes, ST adherence and O, and adherence to all three guidelines and O. Girls showed positive associations between combined PA + sleep adherence and HGS, ST + sleep and O, and negative associations between adherence to two guidelines and BMI. Boys exhibited a negative association between PA and body fat, positive between ST and HGS, and positive/negative between combined PA + ST adherence and HGS/body fat. Moreover, adherence to all three guidelines associated positively with HGS.
Adhering to 24-h movement guidelines, alone or in combination, benefits muscular strength and cardiorespiratory fitness in Brazilian adolescents. However, simultaneous adherence did not correlate with obesity indicators.
研究巴西青少年遵守24小时运动指南（单独和综合）与肌肉力量、心肺适能及肥胖指标之间的联系。
对巴西弗洛里亚诺波利斯980名青少年（14 - 19岁）的数据进行分析。因变量包括体重指数（BMI）、体脂、握力（HGS）、最大耗氧量（ ）。自变量包括身体活动（PA，国际体力活动问卷）、屏幕时间（ST）、睡眠（就寝时间、起床时间）。计算每种行为及组合的依从性。采用多元线性回归模型。
总体依从性：男孩为4.1%，女孩为4.9%。在两性中，PA依从性与HGS/ 均呈正相关，ST依从性与 呈正相关，遵守所有三项指南与 呈正相关。女孩中，PA + 睡眠综合依从性与HGS呈正相关，ST + 睡眠与 呈正相关，遵守两项指南与BMI呈负相关。男孩中，PA与体脂呈负相关，ST与HGS呈正相关，PA + ST综合依从性与HGS/体脂呈正/负相关。此外，遵守所有三项指南与HGS呈正相关。
单独或综合遵守24小时运动指南对巴西青少年的肌肉力量和心肺适能有益。然而，同时遵守与肥胖指标无关。
