Acute Effects of Breaking up Sitting Time With Isometric Wall Squat Exercise on Vascular Function and Blood Pressure in Sedentary Adults: Randomized Crossover Trial.
Purpose: The World Health Organization has recommended breaking up sitting time to improve cardiovascular health. However, whether isometric exercise can be effectively used as a strategy to break up sitting time remains unclear. Thus, the aim of this study was to analyze the acute effects of breaking up prolonged sitting with isometric wall squat exercise (IWSE) on vascular function and blood pressure (BP) in sedentary adults.
Methods: This randomized crossover trial included 17 adults (53% male, 26 ± 6 yr, 22.4 ± 3.6 kg/m 2 ) with high sedentary behavior (≥ 6 hr/d). The participants completed 2 experimental sessions in a randomized order, both sharing a common sitting period of 180 min: Breaks (2-min breaks were incorporated into the IWSE, with participants maintaining their knees at the angle determined by the incremental test, which occurred every 30 min) and Control (sitting for 180 min continuously). Popliteal artery flow-mediated dilation (FMD) and brachial BP were measured before and at 10 and 30 min after the experimental sessions.
Results: The results did not indicate significant session vs time interaction effects on popliteal FMD and brachial BP ( P > .05). A subanalysis including only participants with popliteal FMD reduction after the Control session (n = 11) revealed that Breaks enhanced popliteal FMD after 10 min (1.38 ± 6.45% vs -4.87 ± 2.95%, P = .002) and 30 min (-0.43 ± 2.48% vs -2.11 ± 5.22%, P = .047).
Conclusion: Breaking up prolonged sitting with IWSE mitigates impaired vascular function resulting from prolonged sitting but has no effect on BP in sedentary adults.
期刊介绍:
JCRP was the first, and remains the only, professional journal dedicated to improving multidisciplinary clinical practice and expanding research evidence specific to both cardiovascular and pulmonary rehabilitation. This includes exercise testing and prescription, behavioral medicine, and cardiopulmonary risk factor management. In 2007, JCRP expanded its scope to include primary prevention of cardiovascular and pulmonary diseases. JCRP publishes scientific and clinical peer-reviewed Original Investigations, Reviews, and Brief or Case Reports focused on the causes, prevention, and treatment of individuals with cardiovascular or pulmonary diseases in both a print and online-only format. Editorial features include Editorials, Invited Commentaries, Literature Updates, and Clinically-relevant Topical Updates. JCRP is the official Journal of the American Association of Cardiovascular and Pulmonary Rehabilitation and the Canadian Association of Cardiac Rehabilitation.
