This study aimed to determine which of four selected physical fitness variables, would be most associated with blood pressure changes (systolic and diastolic) in a large sample of adolescents. This was a descriptive and cross-sectional, epidemiological study of 1,117 adolescents aged 14-19 years from southern Brazil. Systolic and diastolic blood pressure were measured by a digital pressure device, and the selected physical fitness variables were body composition (body mass index), flexibility (sit-and-reach test), muscle strength/resistance (manual dynamometer), and aerobic fitness (Modified Canadian Aerobic Fitness Test). Simple and multiple linear regression analyses revealed that aerobic fitness and muscle strength/resistance best explained variations in systolic blood pressure for boys (17.3% and 7.4% of variance) and girls (7.4% of variance). Aerobic fitness, body composition, and muscle strength/resistance are all important indicators of blood pressure control, but aerobic fitness was a stronger predictor of systolic blood pressure in boys and of diastolic blood pressure in both sexes.
本研究旨在确定在一大群青少年样本中，所选取的四个身体素质变量中的哪一个与血压变化（收缩压和舒张压）关联最为密切。这是一项针对来自巴西南部1117名14至19岁青少年的描述性横断面流行病学研究。收缩压和舒张压通过数字压力设备测量，所选取的身体素质变量包括身体成分（体重指数）、柔韧性（坐位体前屈测试）、肌肉力量/耐力（握力计）和有氧适能（改良加拿大有氧适能测试）。简单和多元线性回归分析表明，有氧适能和肌肉力量/耐力对男孩收缩压变化的解释力最强（分别解释方差的17.3%和7.4%），对女孩收缩压变化的解释力为方差的7.4%。有氧适能、身体成分和肌肉力量/耐力都是血压控制的重要指标，但有氧适能对男孩收缩压和两性舒张压的预测性更强。
