NCT01462097

Brief Summary

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.

Outcome Measures

Primary Outcomes (2)

  • Change in Peak Aerobic Capacity

    VO2peak, measured by Graded Exercise Treadmill Test (GXT) with a modified Balke protocol - higher indicates better aerobic capacity

    Baseline, 6 months, 12 months

  • Change in 6 Minute Walk

    Distance walked in 6 minutes - greater distance represents higher function

    Baseline, 6 months, 12 months

Secondary Outcomes (2)

  • Change in Physical Function

    Baseline, 6 months, 12 months

  • Number With Short Physical Performance Battery (SPPB) Score <10 (Out of 12 Maximum)

    Baseline, 6 months, 12 months

Study Arms (2)

Aerobic exercise

EXPERIMENTAL

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

Health Education

ACTIVE COMPARATOR

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.

Limitations and Caveats

1. Study did not meet accrual target 2. Drop-out and loss to follow-up greater than expected, often to due to intercurrent medical events . 3. Moderately greater loss to follow-up in group randomized to exercise training 4. Lack of blinding of outcome assessors 5. Study not designed to have sufficient power to detect effects on secondary outcomes including kidney function. 6. No adjustment for multiple comparisons - risk of type 1 error may be greater than estimated
