未经证实:体脂百分比与动脉僵硬度呈正相关,但不同体脂百分比的个体在有氧运动后动脉僵硬度的急性变化仍不清楚.这项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。
UNASSIGNED:同时参加开滦州研究的第七次调查和第五次国民体质监测的个人都参加了我们的研究。所有参与者都接受了臂-踝脉搏波速度的测量,血压,和心率之前和之后的两阶段负荷测试周期测功。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传导速度变化的组间差异。
未经评估:参与者(N=940,36.8±7.7岁,所有男性)分为:第一季度10.0-19.3%,第二季度19.3-23.3%,第三季度23.3-27.1%和第四季度27.1-37.7%的体脂百分比四分位数。总的来说,锻炼后,臂踝脉搏波传导速度显著降低(之前,1,375.1±209.1;之后,1,341.5±208.0cm/s;p<0.01)。在调整混杂因素后,广义线性模型显示Q1、Q2和Q3组的β值和95%置信区间(CI)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),分别,与Q4相比。对于体脂百分比增加一个标准偏差(5.8%),β=14.5(95%CI:7.3,21.6)。在敏感性分析中获得了类似的结果。
UNASSIGNED:急性有氧运动对具有不同体脂百分比的成年人的动脉僵硬度具有积极作用。与身体脂肪百分比高的个体相比,运动后,体脂百分比低的人的动脉硬度显着降低。
UNASSIGNED: 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.
UNASSIGNED: 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.
UNASSIGNED: The participants (N = 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; p < 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.
UNASSIGNED: 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.
