To explore the application effect of portable wearable device (including muscle oxygen monitor, heart rate armband combined with mobile APP) and exercise management platform in patients with type 2 diabetes mellitus (T2DM).

A total of 66 patients with T2DM were recruited from Department of Endocrinology of the First Affiliated Hospital, Henan University of Science and Technology between May 2017 and June 2018, and randomly divided into the test group (34 cases) and the control group (32 cases). Patients in the test group received portable wearable devices and sport management platform, and the controls received routine sport education. Levels of plasma glucose and lipid, muscle oxygen and heart rate before and after management were compared between these two groups. The t test and chi-square analysis were used for comparison between groups.

After management, levels of glycated hemoglobin A_1c (HbA_1c) and fasting plasma glucose (FPG) in the test group were lower than those in the control group [(7.34±1.61)% vs (6.17±0.53)%, (8.17±2.48) vs (6.30±1.19) mmol/L, respectively; t=-3.248, -3.644, both P<0.05]. The maximum heart rate and the maximum exercise intensity were both higher than those in the control group [(139.00±16.28) vs (129.84±13.00) times/min and 0.80±0.08 vs 0.75±0.05, respectively; t=-2.400, -2.639, both P<0.05]. By increasing speed at 4 min×4 stage of treadmill, the average muscle oxygen ratio and the decrease of muscle oxygen ratio in the test group were both better than those in the control group [(54.79±14.12)% vs (58.00±14.14)%, and (24.56±19.58)% vs (19.03±15.68)%, respectively; t=-4.541, -2.563, both P<0.05].

Intervention combined the portable wearable devices with the sport platform can optimize the exercise management and help to control blood glucose and improve muscle oxygen ratio in patients with T2DM.
