Abstract

Introduction: Sedentary behavior, specifically an acute bout of prolonged uninterrupted sitting is associated with heightened cardiovascular disease (CVD) risk, with increased arterial stiffness (AS) being implicated as a principal pathophysiological mechanism. The current systematic review, with meta-analysis, aimed to consolidate the AS response to: (1) prolonged uninterrupted- and (2) interrupted-sitting, as assessed by central- and peripheral pulse wave velocity (PWV). Methods: In total, 326 articles were identified, of which 11 and 7 met inclusion criteria for objectives: (1) and (2), respectively. Mean differences (MD) and 95% confidence intervals (CI) were calculated for all trials using a three-level random-effects model, with restricted maximum likelihood (REML) estimation. The amount of heterogeneity was estimated using Cochran's Q, and Higgins I2 tests. Results: (1) Prolonged uninterrupted sitting resulted in a significant increase in carotid-femoral (cf) PWV (MD = 0.184 m/s, 95% CI = 0.098 to 0.270, p < 0.0003). (2) Interrupting bouts of prolonged sitting resulted in a significant increase in cf-PWV (MD = 0.127 m/s, 95% CI = 0.044 to 0.209, p < 0.0026), that was lower compared to the uninterrupted sitting. Conclusion: An acute bout of uninterrupted sitting appears to increase cf-PWV and whilst interrupting with brief physical activity it is of benefit; it does not fully mitigate the response.
