Recruiting: Men and women ≥ 60 years old with prediabetes (known or suspected). Potential participants must not regularly exercise (less than 30 minutes, 3x/week).
After consent and screening, the study will involve 2 phases that last 12 weeks each. Before the start and end of each phase (2 testing sessions across 1 week per time point), the following will be conducted:
- Anthropometric analyses
- Hydration status (urine) assessment
- Body composition analyses
- Oral glucose tolerance test
- Physical function testing
- Blood draws (~6 tbsp each)
- Muscle biopsies
- In-muscle temperature measurement (heat therapy group only)
- Exercise capacity testing
- Health habit questionnaires
For Phase 1 (12 weeks), you will be assigned to either:
- Local heat therapy (LHT; 5 days/week at home and 1 day/wk in the Texas Tech lab)
- High intensity interval training (HIIT; exercise in the Texas Tech lab 3 days/wk)
During Phase 2 (12 weeks)
- Only LHT from Phase 1 will continue to HIIT for Phase 2 (exercise in the lab 3 days/wk)
Laboratory visits will take place in the Department of Kinesiology and Sport Management.
Time required: A total of 81.5 hrs for participants who are assigned to the LHT group and a total of 50 hrs for participants who are assigned to the HIIT group.
Participants that complete all aspects of this study will be compensated a total of $1180 or $850 depending on the group assigned for the completion of all aspects of the study.
