超重和肥胖（OW/OB）仍然是青春期女孩的突出健康问题。然而，鲜为人知的是，体力活动（PA），心肺功能（CRF），和OW/OB之间的相互关系，在这个人群中。本研究的目的是探讨CRF是否介导PA和OW/OB之间的关系，在青春期girls.Methods：中度到充满活力的PA（MVPA），CRF，BMI和体脂百分比（% BF）进行了测量，在青春期女孩（N= 1519），年龄10-14岁，从24个城市中学位于美国中西部。使用结构方程模型来确定CRF是否是MVPA和OW/OB（以BMI和% BF测量）之间相关性的介导因子。多组分析被用来确定是否种族，青春期，或社会经济地位温和的mediation models.Results：MVPA通过CRF对OW/OB的间接影响是显着的BMI（p< 0.01）和% BF（p< 0.01），表明CRF是一个完整的MVPA和OW/OB之间的调解人。种族和青春期均显著（p< 0.05）调节MVPA和OW/OB之间的中介作用。结论：本研究表明，增加MVPA可以改善CRF，CRF的改善导致青春期女孩的BMI和% BF降低。
Background:Overweight and obesity (OW/OB) continue to be prominent health issues among adolescent girls. However, little is known about the interrelationships between physical activity (PA), cardiorespiratory fitness (CRF), and OW/OB in this population. The objective of this study was to examine whether CRF mediates the relationship between PA and OW/OB in adolescent girls.Methods:Moderate-to-vigorous PA (MVPA), CRF, BMI, and percentage body fat (% BF) were measured in adolescent girls (N= 1519), aged 10–14 years, from 24 urban middle schools located in the Midwestern United States. Structural equation modeling was used to determine whether CRF is a mediator of the association between MVPA and OW/OB (measured as both BMI and % BF). Multigroup analyses were used to determine whether race, puberty, or socioeconomic status moderate the mediation models.Results:The indirect effect of MVPA through CRF on OW/OB was significant for both BMI (p< 0.01) and % BF (p< 0.01), indicating that CRF is a complete mediator between MVPA and OW/OB. Both race and puberty significantly (p< 0.05) moderated the mediation between MVPA and OW/OB.Conclusions:This study demonstrates that CRF is improved by increasing MVPA, and the improvement in CRF results in lower BMI and % BF among adolescent girls.
