About this study
The main goal of this two-phase clinical trial is to learn whether local heat therapy, using heat pads applied to the legs, can enhance skeletal muscle health, physical function, and blood sugar control in a manner comparable to exercise, specifically High-Intensity Interval Training (HIIT), in older individuals with prediabetes. The study aims to answer the following questions: 1. Does local heat therapy improve muscle architecture (e.g., muscle cross-sectional area, capillary density, mitochondrial content), glucose tolerance, and frailty indicators similarly to HIIT in older individuals with prediabetes? 2. Does local heat therapy as a pre-conditioning method enhance the skeletal muscle response to HIIT in older individuals with prediabetes?

You may qualify if…
- ✓ Age ≥ 50 years
- ✓ Women who are postmenopausal, defined as no menstrual period for at least 12 consecutive months.
- ✓ Sedentary (structured exercise \<30 minutes, 3x/week)
- ✓ Body weight is at least 110 lbs
- ✓ Meet criteria for prediabetes (fasting blood glucose 100-125 mg/dl, hemoglobin A1c 5.7-6.4%)
- ✓ Consume \<8 (women) or \<15 (men) alcohol-containing beverages per week
- ✓ Do not use nicotine or cannabis
- ✓ Not taking any medications that could interfere with responses to the interventions (e.g., corticosteroids, opiates, benzodiazepines, tricyclic antidepressants, beta blockers, sulfonylureas, insulin, metformin, anticoagulants, barbiturates, insulin sensitizers, fibrates, immunosuppressants). If you don't know, that's okay. We'll ask what medications you are on and check whether they fall into one of these categories.
You may not qualify if…
