For adults with prediabetes, exercising on a treadmill for 30 minutes at 70% of their maximum heart rate after eating leads to a larger drop in blood sugar and insulin levels afterward than exercising at lower or higher intensities.

Exercise intensities and metabolic health: Targeting blood glucose, insulin, and C-peptide levels in adults with prediabetes in the postprandial state

Randomized Controlled Trial

Human

2024 Oct

This study found that for people with prediabetes, walking on a treadmill at a moderate-but-challenging pace (70% of max heart rate) after eating lowers blood sugar and insulin better than walking slower or faster. It’s like finding the sweet spot for exercise to help your body manage sugar after meals.

Similar Assertions

For adults with prediabetes, exercising at a higher intensity (80% of maximum heart rate) lowers blood sugar and insulin after meals just as much or more than exercising at a lower intensity (70%), but it feels harder and is harder to keep up over time.

For adults with prediabetes, exercising at 70% of their maximum heart rate lowers blood sugar after a meal by about 50 mg/dL within an hour, more than exercising at lower intensities.

For adults with prediabetes, exercising at 70% of their maximum heart rate helps blood insulin levels return to fasting levels more quickly after eating, which suggests the body is using insulin more efficiently.

If you eat before working out, your blood sugar and insulin levels spike more during exercise than if you work out on an empty stomach.

For adults with prediabetes, exercising at 70% of their maximum heart rate leads to a larger drop in C-peptide levels after eating than exercising at higher or lower intensities, indicating a difference in how the body handles insulin production or demand.
