Last week, Reuters published an article about a Canadian study of the effect on blood sugar control of the order of exercise types. The researchers set up a small study meant to reflect real life exercise situations.
“When participants did aerobic exercise first, blood sugar dropped closer to that threshold and remained lower for the duration of the workout than when they lifted weights first and ran second.
Lifting weights first was also associated with less severe drops in blood sugar hours after exercise, and post-exercise drops that did occur tended to last a shorter period of time.
The current study, published in the journal Diabetes Care, echoes previous research showing that aerobic exercise causes a more rapid decrease in blood sugar than weightlifting.”
TeamWILD’s Diabetes and Nutrition coach, Marcey Robinson, MS, RD, CDE, BC-ADM, noted that she has used this as a tool before for those type 1s who have trouble with BG drops during exercise (either doing some sprint work or weight training first) and it can work like this study talks about, but you always have to be careful about IOB (insulin on board.
