Sedentary Time Negatively Associated with Cardio-metabolic and Inflammatory Biomarkers.

Reading time: 1 – 2 minutes

Taking many breaks from muscular inactivity, even just 1-minute breaks, appears to lower levels of C-reactive protein (CRP) and may result in a smaller waist circumferences. That’s the result of a recent study in the European Heart Journal (study link below), which evaluated sedentary time and breaks in sedentary time with continuous cardio-metabolic and inflammatory risk biomarkers.

Researchers from University of Queensland in Australia evaluated over 4,700 adults and found that prolonged periods of sedentary time, even in people who exercised regularly, were associated with larger waist circumferences, lower levels of HDL, higher levels of CRP and higher triglycerides. Breaks were beneficially associated with waist circumference and CRP.

The researchers write:

These population-based findings provide further evidence on the deleterious associations of sedentary time with cardiometabolic health in adults, and provide novel evidence on the relationship of sedentary time with the inflammatory biomarker CRP. In general, these associations were consistent across sex, age and race/ethnicity.
