The Claim

In adults with type 2 diabetes mellitus, 12 weeks of high-intensity interval training or moderate-intensity continuous training performed three times per week on a cycle ergometer significantly improves maximal oxygen uptake (VO2peak) compared to a non-exercising control group, but there is no significant difference in VO2peak improvement between the two training types.

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

In adults with type 2 diabetes, 12 weeks of either high-intensity interval training or moderate-intensity cycling three times per week increases maximal oxygen uptake compared to no exercise, but the two training methods produce the same improvement in oxygen uptake.

See the scientific wording

In adults with type 2 diabetes mellitus, 12 weeks of either high-intensity interval training or moderate-intensity continuous training, performed three times per week on a cycle ergometer, significantly improves maximal oxygen uptake (VO2peak) compared to a non-exercising control group, but not to each other.

Why this might work

When the muscles work harder during cycling, they demand more oxygen, which triggers the creation of more energy-producing factories inside muscle cells and more tiny blood vessels to deliver oxygen. This lets the body use oxygen more efficiently, raising the maximum amount of oxygen the body can use during intense exercise.

    For people with type 2 diabetes, both fast cycling with breaks and steady moderate cycling, done three times a week for 12 weeks, made their hearts and lungs stronger — but one wasn’t better than the other. Both were better than not exercising at all.
