The effect of age and exercise on beta-cell function after a high-fat meal Original paper

    In this randomized controlled study, exercising before a high-fat meal improved skeletal muscle insulin sensitivity and beta-cell function in younger and older adults; however, older adults experienced reduced adipose insulin sensitivity.

    Quick Summary

    In this randomized controlled study, exercising before a high-fat meal improved skeletal muscle insulin sensitivity and beta-cell function in younger and older adults; however, older adults experienced reduced adipose insulin sensitivity.

    What was studied?

    The effect of exercise and age on beta-cell function in response to a high-fat meal.

    The primary outcome was pancreatic beta-cell function (as measured by the disposition index; DI).

    Other outcomes included skeletal muscle insulin sensitivity (Matsuda index), hepatic (liver) and adipose insulin resistance (measured by HOMA-IR and adipose-IR, respectively), blood lipids (total cholesterol, HDL, LDL, and triglycerides), blood glucose, insulin, and free-fatty acids.
