The purpose of this study was to analyse the associations between sports participation, levels of moderate to vigorous physical activity (MVPA) and cardiorespiratory fitness (CRF). The study comprised 310 participants (183 girls and 127 boys) aged 11-18 years. Sports participation was assessed by questionnaire and habitual physical activity (PA) was measured objectively with accelerometers. The 20-m shuttle-run test was used to estimate CRF. Logistic regression analyses were carried out with CRF as the outcome. The odds ratio (OR) for being fit was greater for those who comply with 60 min · day(-1) in MVPA (OR = 2.612; 95%confidence interval [CI] = 1.614-4.225) in comparison with those who do not. Participation in competitive sports at club levels increased the chances of being fit (OR = 13.483; 95%CI = 4.560-39.864), independently of MVPA levels. There were positive and significant trends in CRF and objectively measured PA across the levels of engagement in competitive sports (P < 0.05). Concluding, participation in competitive sports at club level is more effective than other organised or non-organised sports to reach healthier levels of CRF and recommend levels of MVPA.
本研究旨在分析运动参与、中等到剧烈体力活动（MVPA）水平与心肺功能适应性（CRF）之间的关联。该研究纳入了 310 名 11-18 岁的参与者（183 名女孩和 127 名男孩）。通过问卷评估运动参与情况，使用加速度计客观测量习惯性体力活动（PA）。20 米穿梭跑测试用于估计 CRF。以 CRF 为因变量进行逻辑回归分析。与不遵守 MVPA60 分钟/天的参与者相比，遵守该标准的参与者（OR=2.612；95%置信区间[CI]=1.614-4.225）具有更高的健康适应可能性。与非竞技运动相比，参加俱乐部级别的竞技运动（OR=13.483；95%CI=4.560-39.864）独立增加了健康适应的机会。在参与竞技运动的不同水平上，CRF 和客观测量的 PA 均呈正相关且具有显著趋势（P<0.05）。总之，与其他组织或非组织的运动相比，参加俱乐部级别的竞技运动更有助于达到更健康的 CRF 水平，并推荐达到一定的 MVPA 水平。
