The Claim
In adults with prediabetes, performing exercise at 70% of predicted maximum heart rate leads to insulin levels returning closest to fasting values within 60 minutes after a meal compared to other exercise intensities or no exercise.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
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.
See the scientific wording
In adults with prediabetes, exercise at 70% of predicted maximum heart rate results in insulin levels returning closest to fasting values within 60 minutes post-meal, indicating improved insulin sensitivity or reduced insulin demand.
When you exercise at a moderate-to-high intensity, your muscle cells become better at taking sugar from your blood. They do this by putting more sugar transporters on their surface. This means your body doesn't need to make as much insulin to move sugar into cells. So after a meal, your insulin levels drop back to normal faster.
What the research says
1 studyThis study found that when people with prediabetes exercise at 70% of their max heart rate, their body needs less insulin after eating, and insulin levels go back to normal faster than with other exercise intensities.
