Chronic Kidney Disease (CKD) is exceedingly common in older adults, in whom it is associated with impairment in cognition and physical function. The purpose of this study is to test the effects of 12 months of aerobic and resistance exercise training compared to health education on cognitive and physical performance in 120 older adults with CKD not requiring dialysis. The results of this study will be essential for demonstrating the effectiveness of exercise in improving function and ultimately preventing disability in this high-risk population of older adults.

Primary Outcome Measures:
  • Change in neurocognitive function [ Time Frame: Baseline, 6 months, 12 months ]
    Executive function, psychomotor speed, memory, learning

  • Change in peak aerobic capacity [ Time Frame: Baseline, 6 months, 12 months ]

Arms Assigned Interventions
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

Detailed Description:

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.
