Experimental: Aerobic exercise
12 months of treadmill walking and strength training exercise. Exercise is gradually progressed in walking speed and time on the treadmill based on the individual's tolerance, abilities, and safety. For months 1-6 exercise will take place 3 times per week at the research center. For months 6-12 exercise will take place 2 times per week at the center and 1 time per week at home.
Behavioral: Aerobic exercise training
12 months of aerobic exercise
Active Comparator: Health Education
12 months of Health education sessions which will cover topics important to older adults (safe travel, age-appropriate preventative screenings, resources for reliable health information, and topics relevant to chronic kidney disease). For months 1-6 classes will take place 1 time per week. For months 6-12 classes will take place 1 time per month.
Behavioral: Health Education
12 months of health education sessions
This is a parallel-group randomized controlled trial comparing 12 months of aerobic and resistance exercise training vs. health education (attention control) on neurocognitive and physical performance among community-dwelling older adults (age >55) and CKD stage 3b and 4. Co-primary outcomes are change in physical performance (including aerobic capacity and submaximal walking) and neurocogntivie performance (including executive functions).
Outcome measures will be assessed at baseline and after 6- and 12 months. Exercise training will occur thrice weekly at a dedicated research exercise center and will be supervised by exercise specialists.
