The effect of acute aerobic exercise on arterial stiffness in individuals with different body fat percentages: A cross-sectional study

Abstract

BackgroundBody 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.MethodsIndividuals 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.ResultsThe 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.ConclusionsAcute 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.

Comparison of Performance in the Six-Minute Walk Test (6MWT) between Overweight/Obese and Normal-Weight Children and Association with Haemodynamic Parameters: A Cross-Sectional Study in Four Primary Schools

“…In a Chinese study involving 940 male participants (average age 36.8 years, average BMI 26 kg/m 2 ) who underwent a two-stage load test on cycle ergometry, the results indicated that at the end of the exercise, HR increased in all quintiles of body fat percentage, while BP did not show a significant increase [49].…”

Better Option for Improving Metabolic Syndrome: Consideration of the Amount and Duration of Resistance Exercise or Physical Activity

“…Previous studies have reported that PA negatively associated with the prevalence of MetS [25,26]. Recent studies have shown that PA or aerobic exercise can improve various components of MetS, including body composition [27,28], insulin resistance and lipid metabolism [29][30][31], and cardiovascular function [31,32]. Specifically aerobic exercise reduces chronic inflammation, increases energy expenditure, and increases expression of PGC-1a, which protects against mitochondrial diseases such as apoptosis and oxidative damage [28][29][30][31].…”
