目的1)了解肥胖儿童左心室结构和功能与全身成分、内脏脂肪组织(VAT)和血流动力学的关系；2)确定4个月运动对左心室结构和功能及血流动力学的影响；3)探讨个体变异的影响因素。方法采用超声心动图测量左心室结构和功能，双能X线吸收法测量整体身体成分，核磁共振(MRI)测量VAT，Dinamap监护仪和多普勒超声心动图测量安静和运动血流动力学。在8个月的干预期中，年轻人被随机分配到第一个或第二个4个月期间进行PT。结果基线时的相关和回归显示，LV质量增加与全身和内脏肥胖过度以及心输出量增加相关。尽管PT对体脂百分比和增值税有良好的影响，但对LV和血流动力学变量没有明显的影响。在PT干预的4个月期间，VAT增加最多的人往往增加最多的LV质量。结论全身肥胖症和内脏肥胖与LV质量升高有关。然而，没有证据表明PT治疗4个月对LV或血流动力学变量有显著影响。
Purpose1) To determine the relations of left ventricular (LV) structure and function to total body composition, visceral adipose tissue (VAT), and hemodynamics in obese children; 2) to determine the effects of 4-month of physical training (PT) on LV structure and function and hemodynamics; and 3) to explore determinants of individual variability in response to PT.MethodsMeasurements included LV structure/function with echocardiography, total body composition with dual-energy x-ray absorptiometry, VAT with magnetic resonance imaging (MRI), and resting and exercising hemodynamics with a Dinamap monitor and Doppler-echocardiography. Youths were randomly assigned to engage in PT for the first or second 4-month periods of the 8-month intervention period.ResultsCorrelation and regression at baseline showed that elevated LV mass was associated with excess general and visceral adiposity, and elevated cardiac output. Although the PT had favorable effects on percent body fat and VAT, no significant changes were found in LV or hemodynamic variables. Over the 4-month period of the PT intervention, those who increased the most in VAT tended to increase the most in LV mass.ConclusionGeneral and visceral adiposity were associated with elevated LV mass. However, no evidence was provided that 4 months of PT had a significant effect on LV or hemodynamic variables.
