• Intervention
    What is the effect of physical activity (for at least 3 months) combined with MNT on metabolic outcomes in persons with type 2 diabetes?
    • Conclusion

      In people with type 2 diabetes, 90 - 150 minutes of weekly physical activity (both aerobic exercise and resistance/strength training) reduces A1C, improves insulin sensitivity, and decreases relative risk for all-cause mortality. 

    • Grade: I
      • Grade I means there is Good/Strong evidence supporting the statement;
      • Grade II is Fair;
      • Grade III is Limited/Weak;
      • Grade IV is Expert Opinion Only;
      • Grade V is Not Assignable.
      • High (A) means we are very confident that the true effect lies close to that of the estimate of the effect;
      • Moderate (B) means we are moderately confident in the effect estimate;
      • Low (C) means our confidence in the effect estimate is limited;
      • Very Low (D) means we have very little confidence in the effect estimate.
      • Ungraded means a grade is not assignable.

    What is the effect of physical activity combined with Medical Nutrition Therapy (MNT) on metabolic outcomes in persons with type 1 diabetes?
    • Conclusion
      In persons with type 1 diabetes, the incidence of hypoglycemia during exercise depends on baseline glucose levels, and exercise often results in overnight hypoglycemia.  Glycemic control generally does not improve in response to ongoing participation in physical activity alone.  One study reported possible gender differences in A1C; further research is needed in this area.
