简要总结
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.
详细描述
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 neurocogntive 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.

结局指标
主要结局
Change in Peak Aerobic Capacity
时间窗: Baseline, 6 months, 12 months
VO2peak, measured by Graded Exercise Treadmill Test (GXT) with a modified Balke protocol - higher indicates better aerobic capacity
Change in 6 Minute Walk
时间窗: Baseline, 6 months, 12 months
Distance walked in 6 minutes - greater distance represents higher function
次要结局
- 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)
