MedicalResearch.com: What is the background for this study? What are the main findings?

Response: We conducted this study because separate lines of inquiry have determined that a bout of exercise can acutely lower blood pressure, and more recently that prolonged sitting can increase blood pressure over the space of a day. We wanted to know whether the blood pressure lowering effects of an exercise bout would be diminished by a subsequent period of prolonged sitting or enhanced by a subsequent period of sitting that is regularly interrupted with short walking breaks.

We found an additive blood pressure lowering effect when exercise was combined with breaks in sitting as opposed to exercise plus prolonged sitting. However, this was only true for women. Men had equal blood pressure lowering effects following exercise regardless of whether-or-not subsequent sitting was interrupted Continue reading
