The Claim

In prediabetic adults, a single bout of moderate-intensity and high-intensity exercise matched for caloric expenditure produces similar improvements in insulin sensitivity, with no statistically significant difference between the two intensities.

Source: Effects of exercise intensity on postprandial improvement in glucose disposal and insulin sensitivity in prediabetic adults.

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.

Cause and effect
1 study reviewed
In plain English

For people with prediabetes, doing one workout of either medium or hard intensity, as long as they burn the same calories, both help the body use insulin better to control blood sugar, and neither is better than the other.

See the scientific wording

In prediabetic adults, a single bout of moderate-intensity and high-intensity exercise matched for caloric expenditure produces similar improvements in insulin sensitivity, with no statistically significant difference between the two intensities.

Why this might work

When you exercise, your muscles use up their stored sugar. After exercise, your muscles work to refill that sugar supply, which makes your body better at controlling blood sugar. Whether you exercise at a moderate or hard pace, if you burn the same amount of energy, your muscles use up a similar amount of stored sugar, so your body improves its insulin sensitivity in a similar way.

  1. Study: Effects of exercise intensity on postprandial improvement in glucose disposal and insulin sensitivity in prediabetic adults.

    The study compared moderate and hard exercise in people with prediabetes, making sure both burned the same calories. It found that both types improved the body's ability to handle sugar, and the improvement was about the same for both, even though hard exercise showed a slightly bigger number but not a real difference.
