PURPOSE
The present study describes the distribution of cardiorespiratory fitness (VO2peak) in a large sample of healthy adolescents and the associations between VO2peak, self-reported physical activity, and a selection of conventional markers for future cardiovascular health.
METHODS
In a substudy of the Young-HUNT study in Norway, 570 adolescents (289 girls and 281 boys) 13–18 yr. old were tested for directly measured VO2peak. Blood pressure, resting heart rate, height, weight, and waist circumference was measured by standardized procedures. Data about physical activity and pubertal development were obtained using self-administered questionnaires. General linear modeling and ANOVA were used to examine the relationships between VO2peak and age, physical activity, and cardiovascular risk factors.
RESULTS
The mean T SD VO2peak was 183.9 +/- 24.6 mL x kg(-0.67) x min(-1) (49.2 mL x kg(-0.67) x min(-1)) in girls and 235.1 +/- 35.3 mL x kg(-0.67) x min(-1) (59.5 mL x kg(-0.67) x min(-1)) in boys. Absolute VO2peak (L x min(-1)) was consistently higher in older age groups in both sexes (P trend < 0.001). VO2peak allometrically scaled to body mass (mL x kg(-0.67) x min(-1)) was similar across the age groups in girls (i.e., difference between 13- to 14-yr-olds and 17- to 18-yr-olds = -3.2 mL x kg(-0.67) x min(-1), 95% confidence interval = 3.8 to -10.1) and slightly higher in the older age groups in boys (i.e., difference between 13- to 14-yr-olds and 15- to 16-yr-olds = -31.0 mL x kg(-0.67) x min(-1), 95% confidence interval = -22.0 to -40.1). Physical activity was positively associated with VO2peak in all sex and age groups. Quartiles of VO2peak were inversely associated with resting heart rate (P trend = 0.004) in both sexes and body mass index (P trend = 0.004) and waist circumference (P trend = 0.006) in boys.
CONCLUSION
Although VO2peak was generally high across the age groups, VO2peak was higher in physically active adolescents of both sexes and physical activity in accordance with the recommended level may be sufficient to maintain or even increase VO2peak through adolescence.
目的
本研究描述了大量健康青少年的心肺适能（VO2peak）分布情况，并探讨了 VO2peak 与自我报告的体力活动以及一系列未来心血管健康的常规标志物之间的关系。
方法
在挪威 Young-HUNT 研究的一项子研究中，对 570 名 13-18 岁的青少年（289 名女孩和 281 名男孩）进行了直接测量的 VO2peak 测试。血压、静息心率、身高、体重和腰围通过标准化程序进行测量。使用自我管理问卷获取有关体力活动和青春期发育的数据。采用一般线性模型和方差分析来检验 VO2peak 与年龄、体力活动和心血管风险因素之间的关系。
结果
女孩的平均 VO2peak 为 183.9 ± 24.6 mL x kg(-0.67) x min(-1)（49.2 mL x kg(-0.67) x min(-1)），男孩为 235.1 ± 35.3 mL x kg(-0.67) x min(-1)（59.5 mL x kg(-0.67) x min(-1)）。在两性中，绝对 VO2peak（L x min(-1)）随着年龄组的增加而持续升高（P 趋势 < 0.001）。在女孩中，VO2peak 与体重的幂函数标度（mL x kg(-0.67) x min(-1)）在各年龄组之间相似（即 13-14 岁与 17-18 岁之间的差异 = -3.2 mL x kg(-0.67) x min(-1)，95%置信区间为 3.8 至-10.1），而在男孩中，该差异在较大年龄组中稍高（即 13-14 岁与 15-16 岁之间的差异 = -31.0 mL x kg(-0.67) x min(-1)，95%置信区间为 22.0 至-40.1）。在所有性别和年龄组中，体力活动与 VO2peak 呈正相关。在两性中，VO2peak 的四分位数与静息心率（P 趋势 = 0.004）呈负相关，与男孩的体重指数（P 趋势 = 0.004）和腰围（P 趋势 = 0.006）呈负相关。
结论
尽管 VO2peak 在各年龄组中普遍较高，但在两性中，活跃的青少年的 VO2peak 更高，并且符合建议水平的体力活动可能足以维持甚至增加青少年时期的 VO2peak。
