Sedentary Behavior Interrupted: A Trial of Acute Effects on Biomarkers of Healthy Aging
Status unconfirmed · Not applicable
Conditions studied: Sedentary Lifestyle
In brief
This protocol "Sedentary Behavior Interrupted: A randomized crossover trial of acute effects on biomarkers of healthy aging in the laboratory (Project 1)" is part of a National Institutes of Aging Program Grant called "Sedentary Time \& Aging Mortality and Physical Function (STAR). The overall purpose of the STAR program to is to better understand how to interrupt sitting time and the consequences for healthy aging in postmenopausal women. This protocol (also referred to Project 1 of the STAR program) is a 3-condition randomized crossover clinical trial of up to 86 postmenopausal women to test whether different interruptions to prolonged sitting improve metabolism.
