The authors looked at the following variables and their impact on cardiometabolic risk factors (ie. glucose, triglycerides and HDL cholesterol): sedentary time, breaks in sedentary time (which is defined as a transition from a sedentary to an active state), MVPA (moderate to vigorous physical activity) and total physical activity.
Their findings showed that breaks in sedentary time, total physical activity and MVPA were significantly inversely associated with measure of adiposity but not with any other cardiometabolic variables. This means that the amount of time that was spent being active was associated with the participants having less fat. These results were consistent across age groups, which means that excess sedentary time has negative consequences from young adulthood through older ages (18-74 years).
A unique aspect of this study is that they found that the actual time spent being sedentary throughout the day is also detrimental on health. So, the moral of the article is that *in addition* to simply aiming for 20-30 minutes of moderate to vigorous activity a day, people should also focus on sitting less and moving more throughout the day, regardless of the intensity level of the activity!
