Arterial stiffness increased during prolonged sitting, even when sitting was interrupted
A pooled trial analysis reported increased central arterial stiffness with uninterrupted sitting and a smaller increase with activity interruptions. Participant details and exact sitting durations were not provided in the abstract.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
For participants in trials of prolonged sitting, the pooled analysis found increased central arterial stiffness with both uninterrupted sitting and sitting interrupted by brief physical activity. The reported increase was smaller with interruptions, but was not eliminated. These are responses to an acute sitting exposure; the abstract does not establish long-term cardiovascular benefits.
The abstract gives no separate effect estimate for the interrupted-versus-uninterrupted comparison and does not report peripheral artery results, despite including them in its question.
A vascular measurement
Pulse wave velocity measures how quickly a pulse travels through arteries. The central measure was used here to assess arterial stiffness. An increase describes a vascular measurement, rather than a recorded heart attack or another cardiovascular event.
What interruptions changed
Both sitting conditions showed statistically detectable increases in the central measure. The review describes a smaller response when sitting was interrupted. However, the abstract does not specify the activities or timing of interruptions, limiting how precisely readers can understand that comparison.
