AIM: Pedometers and accelerometers have recently become applicable for not only monitoring but increasing level of physical activity (PA). We summarize the effects of pedometer- and accelerometer-based exercise interventions on glucose metabolism in subjects with diabetes mellitus (DM).
METHODS: We searched intervention studies that investigated the effects of step-defined exercise interventions using pedometers and accelerometers on the levels of glucose metabolism markers, such as plasma glucose and hemoglobin A1c (HbA1c), in adult subjects with type 2 DM. The study characteristics and findings of glucose metabolism markers were reviewed.
RESULTS: Of 16 eligible studies reviewed, significant improvements in glucose metabolism markers were found in the intervention group compared to that observed in the control group in six studies: the HbA1c level in four studies, both the HbA1c and plasma glucose levels in one study and continuous glucose monitoring in one study. Four of these six studies emphasized a significance of PA intensity in addition to PA amount. Five studies found a significant increase in the number of steps, but only one of these studies showed significant reductions in glucose metabolism markers. No studies demonstrated a dose-response relationship between changes in the number of steps and glucose metabolism markers.
CONCLUSION: Limited studies showed significant improvements in glucose metabolism markers and steps among subjects with type 2 DM. Future studies are needed regarding how to use pedometers and accelerometers to achieve improvements in glucose metabolism with increases in PA in such subjects, especially more focus on PA intensity.
