The Claim

Moderate-intensity resistance training performed three times per week for 3 to 6 months reduces fasting plasma glucose by an average of 29.1 mg/dL in middle-aged and older adults with type 2 diabetes, and it is the only exercise modality with statistically significant and moderate-certainty evidence for improving this specific marker of basal insulin sensitivity.

In plain English

In middle-aged and older adults with type 2 diabetes, doing moderate-intensity resistance training three times per week for 3 to 6 months lowers fasting blood glucose by an average of 29.1 mg/dL, and among all forms of exercise, only this type has been shown with moderate-certainty evidence to produce this specific change.

See the scientific wording

Moderate-intensity resistance training performed three times per week for 3 to 6 months reduces fasting plasma glucose by an average of 29.1 mg/dL in middle-aged and older adults with type 2 diabetes, which is the only exercise modality with statistically significant and moderate-certainty evidence for improving this specific marker of basal insulin sensitivity.

Why this might work

When muscles contract during moderate weight lifting, they become more responsive to insulin, which allows more glucose to leave the blood and enter muscle cells. This happens because the muscle cells move more glucose transporters to their surface, and this effect lasts long enough to lower blood sugar levels even after fasting overnight.

  1. Study: Comparative effects of different intensities of aerobic and resistance exercise on glycemic control and cardiorespiratory fitness in middle-aged older patients with type 2 diabetes: a network meta-analysis

    This study found that lifting weights at a moderate pace three times a week lowered fasting blood sugar in older adults with diabetes — more than other types of exercise — and it’s the only kind of exercise with strong enough evidence to be sure of this effect.
