The Claim
In adults with prediabetes, exercise performed at 70% of predicted maximum heart rate reduces postprandial glucose levels by approximately 50 mg/dL within 60 minutes, and this reduction is significantly greater than that observed at 50% or 60% of predicted maximum heart rate.
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 lowers blood sugar after a meal by about 50 mg/dL within an hour, more than exercising at lower intensities.
See the scientific wording
In adults with prediabetes, exercise at 70% of predicted maximum heart rate reduces postprandial glucose levels by approximately 50 mg/dL within 60 minutes, which is significantly greater than reductions seen at 50% or 60% intensity.
When you exercise at a good intensity, your muscles need energy. They take sugar from your blood to use as fuel. Exercise does this by opening special doors on muscle cells that let sugar in. The more intense the exercise (like at 70% of your max heart rate), the more doors open, so more sugar leaves your blood. This helps bring your blood sugar down after a meal. Lower intensity exercise opens fewer doors, so it doesn't lower blood sugar as much.
What the research says
1 studyThis study found that when people with prediabetes exercise at 70% of their max heart rate, their blood sugar drops more after eating than when they exercise at lower intensities. So yes, working out harder (but not too hard) helps control blood sugar better.
