Short sleep duration is prevalent in modern society and may be contributing to type 2 diabetes prevalence. This course will explore the effects of sleep restriction on glycemic control, the mechanisms causing insulin resistance, and whether exercise can offset changes in glycemic control.…
Key Points:
Habitual sleep restriction (<7 h/night) is widespread in modern society and may be contributing to the development of type 2 diabetes by inducing insulin resistance in multiple tissues
Whole body glucose tolerance is impaired with sleep restriction but skeletal muscle ( e.g. , reduced peripheral insulin sensitivity) and adipose tissue ( e.g. , impaired insulin signaling and increased nonesterified fatty acid concentrations) appear to be the tissues most affected
Because exercise is known to improve insulin sensitivity in these tissues, it has been investigated as a therapeutic to counteract the negative ramifications of sleep restriction, and high-intensity interval training appears to be most effective
