ABSTRACT

OBJECTIVE:

The objective of the study was to investigate the associations of sedentary time, physical activity, and cardiorespiratory fitness with skeletal muscle glucose uptake (GU).

METHODS:

Sedentary time and physical activity were measured with accelerometers and VO2 max with cycle ergometry in 44 sedentary adults with metabolic syndrome. Thigh muscle GU was determined with [18 F]FDG-PET imaging.

RESULTS:

Sedentary time (ß = -0.374), standing (ß = 0.376), steps (ß = 0.351), and VO2 max (ß = 0.598) were associated with muscle GU when adjusted for sex, age, and accelerometer wear time. Adjustment for body fat-% turned all associations non-significant.

CONCLUSION:

Body composition is a more important determinant of muscle GU in this population than sedentary time, physical activity, or fitness.
