Key finding
Strength increases were maintained through month 15 and represented improvements of 21% and 14% for chest and leg press.
This trial tested whether adults with prediabetes could start and maintain resistance training. After a supervised 3-month training phase, about one-third of participants were no longer prediabetic, and this was mostly maintained through 15 months. Extra social-cognitive support did not outperform lower-contact standard care.

Study focus
This trial tested whether adults with prediabetes could start and maintain resistance training. After a supervised 3-month training phase, about one-third of participants were no longer prediabetic, and this was mostly maintained through 15 months. Extra social-cognitive support did not outperform lower-contact standard care.
Prediabetes often progresses to type 2 diabetes, and many prevention programs rely on broad lifestyle changes that can be hard to maintain. This study suggests that a focused resistance training program may be a practical single-component strategy for some older adults with prediabetes. However, the trial did not include a no-exercise control group, so the benefit of resistance training alone should be interpreted cautiously.
No no-exercise control group over the full 15-month trial Participants were mostly White, female, and college educated Maintenance adherence declined by month 15 Findings may not generalize to younger or more diverse populations
Normoglycemia status ↑ (34% after 3 months; 30% at 15 months)
Muscular strength ↑ (chest press 21%, leg press 14%)
Fasting plasma glucose → (no clear change reported)
