Aerobic vs Resistance Exercise in Post-menopausal Women With Type 1 Diabetes
Acute Glycemic Effects of Aerobic and Resistance Exercise in Post-menopausal Women With Type 1 Diabetes
University of Alberta
20 participants
Nov 16, 2021
INTERVENTIONAL
Conditions
Summary
Participants will be asked to wear a continuous glucose monitor for at least three days on three separate occasions. One testing session will be a no-exercise resting control session (90 minutes). One will be a moderate aerobic exercise session (30 minutes of exercise, 60 minutes of recovery), and the third will be a moderate weight-lifting session (\~30 minutes of exercise, 60 minutes of recovery).The investigators will measure changes in blood glucose during exercise by drawing blood during and after exercise. Post-exercise glucose trends will be examined using continuous glucose monitoring.
