The Claim

In adults with type 2 diabetes mellitus, 12 weeks of isoenergetic high-intensity interval training or moderate-intensity continuous training performed three times per week on a cycle ergometer has no significant effect on HbA1c levels, glucose, insulin resistance, blood lipids, cardiovascular responses, anthropometric measures, body composition, or abdominal and visceral fat compared to a non-exercising control group.

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

In adults with type 2 diabetes, doing either high-intensity interval training or moderate continuous cycling three times a week for 12 weeks does not change HbA1c, blood glucose, insulin resistance, blood lipids, cardiovascular measures, body weight, body composition, or fat around the abdomen and organs compared to not exercising.

See the scientific wording

In adults with type 2 diabetes mellitus, 12 weeks of isoenergetic high-intensity interval training or moderate-intensity continuous training, performed three times per week on a cycle ergometer, does not significantly improve HbA1c levels, glucose, insulin resistance, blood lipids, cardiovascular responses, anthropometric measures, body composition, or abdominal and visceral fat compared to a non-exercising control group.

Why this might work

When people with type 2 diabetes do the same amount of cycling exercise at high or low intensity, their muscles do not take up more sugar from the blood, and their liver does not reduce how much sugar it releases, so blood sugar levels stay the same.

  1. Study: Is isoenergetic high-intensity interval exercise superior to moderate-intensity continuous exercise for cardiometabolic risk factors in individuals with type 2 diabetes mellitus? A single-blinded randomized controlled study

    This study found that for people with type 2 diabetes, doing either short bursts or longer steady cycling three times a week for 12 weeks didn’t lower blood sugar or improve heart and body fat measures any more than just sitting around — even though they got a bit fitter.
