Research from several countries has documented a decline in physical activity (PA) levels and in participation in organized sport with increasing age, indicating that organized sport may be of importance to adolescents' cardiorespiratory fitness (CRF).
The purpose of this study was to examine how regular participation in organized and unorganized PA affected the development of adolescents' CRF (peak oxygen consumption [VOpeak]), when controlled for sex interaction.
Data on direct measures of VOpeak and participation in organized PA among adolescents organized into 3 groups (participation in organized sport, participation in unorganized PA, and no weekly PA) were collected from 76 students (39 boys and 37 girls), when they were aged 14 and 19 years old.
Statistically significant differences were found between VOpeak values in the 3 groups at both 14 years of age, F(2, 73) = 7.16, p < .05, ƞ = .170, and 19 years of age, F(2, 73) = 14.00, p < .05, ƞ = .300, independent of sex at both 14 and 19 years of age, F(2, 73) = 0.05, p > .05, ƞ = .02, and F(2, 73) = 0.05, p > .05, ƞ = .00. Adolescents participating in organized sport also had statistically significantly higher VOpeak values than adolescents participating in unorganized PA and those with no weekly PA, at both 14 and 19 years of age.
From a health perspective, in terms of CRF, the findings highlight the importance of encouraging adolescents to participate in organized sport and to refrain from dropping out of organized sport programs.
来自多个国家的研究表明，随着年龄增长，身体活动（PA）水平及参与有组织体育运动的情况呈下降趋势，这表明有组织的体育运动对青少年的心肺适能（CRF）可能很重要。
本研究的目的是在控制性别交互作用的情况下，研究定期参与有组织和无组织的PA如何影响青少年CRF（峰值耗氧量[VOpeak]）的发展。
收集了76名学生（39名男生和37名女生）在14岁和19岁时的VOpeak直接测量数据以及他们参与有组织PA的情况，这些学生被分为3组（参与有组织的体育运动、参与无组织的PA、无每周PA）。
在14岁时，三组VOpeak值之间存在统计学显著差异，F(2, 73) = 7.16，p <.05，ƞ =.170；在19岁时，F(2, 73) = 14.00，p <.05，ƞ =.300，且在14岁和19岁时均与性别无关，F(2, 73) = 0.05，p >.05，ƞ =.02，以及F(2, 73) = 0.0可以，p >.05，ƞ =.00。在14岁和19岁时，参与有组织体育运动的青少年的VOpeak值也显著高于参与无组织PA的青少年和无每周PA的青少年。
从健康角度来看，就CRF而言，研究结果凸显了鼓励青少年参与有组织体育运动并避免退出有组织体育项目的重要性。
