BACKGROUND
Body fat percentage were positively correlated with arterial stiffness, but the acute change in arterial stiffness after aerobic exercise in individuals with different body fat percentages remains unclear. This study was aimed to determine the effect of acute aerobic exercise on arterial stiffness in individuals with different body fat percentages.
METHODS
Individuals who both participated in the seventh survey of the Kailuan study and the fifth iteration of National Physical Fitness Monitoring were enrolled in our study. All participants underwent measurement of brachial-ankle pulse wave velocity, blood pressure, and heart rate before and after a two-stage load test on cycle ergometry. Additionally, the generalized linear model was established to analyse between-group differences of the change in brachial-ankle pulse wave velocity before and after exercise for individuals with different body fat percentages.
RESULTS
The participants ( = 940, 36.8 ± 7.7years old, all male) were divided into: Q1 10.0-19.3%, Q2 19.3-23.3%, Q3 23.3-27.1% and Q4 27.1-37.7% by body fat percentage quartile. Overall, after exercise, brachial-ankle pulse wave velocity decreased significantly (before, 1,375.1 ± 209.1; after, 1,341.5 ± 208.0cm/s; < 0.01). After adjusting for confounding factors, the generalized linear model showed that the β values and 95% confidence interval (CI) of Q1, Q2 and Q3 groups were -38.1 (95% CI: -57.3, -19.0), -8.5 (95% CI: -25.8, 3.7),-3.7 (95% CI: -20.5, 13.0), respectively, when compared with Q4. For an increase in body fat percentage by one standard deviation (5.8%), β = 14.5 (95% CI: 7.3, 21.6). Similar results were obtained in sensitivity analyses.
CONCLUSIONS
Acute aerobic exercise had a positive effect on the arterial stiffness of adults with different body fat percentages. Compared with individuals with high body fat percentages, the arterial stiffness of people with low body fat percentages had significant reduction after exercise.
背景
体脂百分比与动脉僵硬度呈正相关，但不同体脂百分比个体有氧运动后动脉僵硬度的急性变化尚不清楚。本研究旨在确定急性有氧运动对不同体脂百分比个体动脉僵硬度的影响。
方法
参加开滦研究第七次调查和国民体质监测第五次复测的个体纳入本研究。所有参与者在进行两级蹬车负荷试验前后均测量了臂踝脉搏波速度、血压和心率。此外，建立广义线性模型分析不同体脂百分比个体运动前后臂踝脉搏波速度变化的组间差异。
结果
参与者（n = 940，36.8±7.7岁，均为男性）按体脂百分比四分位数分为：Q1 10.0 - 19.3%，Q2 19.3 - 23.3%，Q3 23.3 - 27.1%和Q4 27.1 - 37.7%。总体而言，运动后臂踝脉搏波速度显著降低（运动前，1375.1±209.1；运动后，1341.5±208.0cm/s；P < 0.01）。调整混杂因素后，广义线性模型显示，与Q4组相比，Q1、Q2和Q3组的β值及95%置信区间（CI）分别为-38.1（95%CI：-57.3，-19.0）、-8.5（95%CI：-25.8，3.7）、-3.7（95%CI：-20.5，13.0）。体脂百分比每增加一个标准差（5.8%），β = 14.5（95%CI：7.3，21.6）。敏感性分析得到类似结果。
结论
急性有氧运动对不同体脂百分比的成年人动脉僵硬度有积极影响。与高体脂百分比个体相比，低体脂百分比个体运动后动脉僵硬度显著降低。
