The Claim

In prediabetic adults, a single bout of moderate-intensity exercise significantly lowers the 2-hour glucose concentration during an oral glucose tolerance test by approximately 16 mg/dL compared to rest, and a single bout of high-intensity exercise significantly lowers it by approximately 27 mg/dL compared to rest.

Cause and effect
1 study reviewed
In plain English

For people with prediabetes, doing one exercise session (either moderate or intense) can lower the blood sugar level measured two hours after drinking a sugary drink, compared to resting. Moderate exercise lowers it by about 16 mg/dL, and intense exercise lowers it by about 27 mg/dL.

See the scientific wording

In prediabetic adults, both a single bout of moderate-intensity and high-intensity exercise can significantly lower the 2-hour glucose concentration during an oral glucose tolerance test compared to rest, with reductions of approximately 16 mg/dL and 27 mg/dL respectively.

Why this might work

When you exercise, your muscles use up their stored sugar (glycogen). This makes your muscles better at taking sugar out of your blood later. Hard exercise also makes your body release a burst of adrenaline, which temporarily puts more sugar in your blood, but then your body makes extra insulin to clear it and refill the muscles. After that, your body handles sugar better, so your blood sugar stays lower after a sugary drink.

    The study showed that both moderate and hard exercise helped prediabetic people keep their blood sugar lower after a sugary drink, just like the claim says.
