Acute Effects of Cold-induced Shivering on 24-hour the Glucose Profile in Metabolically Compromised Populations
Effects of Cold-induced Shivering at Different Intensities on 24-hour Glucose Profiles in Pre-diabetic Individuals and Patients With Type 2 Diabetes Mellitus

Rövid összefoglaló (regiszter, angolul)
Type 2 Diabetes Mellitus (T2DM) and its associated comorbidities pose a major health concern worldwide. Although lifestyle strategies, such as exercise and diet-induced weight loss are effective interventions to counteract the development and progression of the disease, its prevalence continues to increase. Therefore, alternative therapeutic strategies are warranted. One such method, which has increasingly been gaining attention, is cold exposure. Previously, investigators have shown that exposing T2DM patients to mild cold (14-16 oC) for 6 hours per day for 10 consecutive days enhanced their insulin sensitivity by ~43%. This remarkable improvement in insulin sensitivity was accompanied by robust GLUT4 translocation in the skeletal muscle of participants, which likely mediated the improvements in insulin-stimulated glucose uptake. Follow-up research suggested that a certain degree of muscle activation/shivering appears to be a prerequisite for the cold-induced enhancement in skeletal muscle insulin-stimulated glucose uptake. In humans however, very little information is available about the effects of shivering on glucose metabolism, especially in metabolically compromised individuals. Therefore, in this study, the aim to investigate the acute effects of (different intensities of) shivering on 24-hour glucose profiles in pre-diabetic individuals as well as in T2DM patients. For that purpose, a focus will be placed on clinically relevant glycaemic parameters by means of continuous glucose monitoring, which is increasingly being used in T2DM management and prevention.
