Breaking up prolonged sitting alters the postprandial plasma lipidomic profile of adults with type 2diabetes

Abstract

Context: Postprandial dysmetabolism in type 2 diabetes (T2D) is exacerbated by prolonged sitting and may trigger inflammation and oxidative stress. It is unknown what impact countermeasures to prolonged sitting have on the postprandial lipidome. Objective: In this study, we investigated the effects of regular interruptions to sitting, compared with prolonged sitting, on the postprandial plasma lipidome. Design: Randomized crossover experimental trial. Setting: Participants underwent three 7-hour conditions: uninterrupted sitting (SIT); light-intensity walking interruptions (LW); and simple resistance activity interruptions (SRA). Participants and Samples: Baseline (fasting) and 7-hour (postp..
