pro-social power training activity for aging and well-being with chronic kidney disease

Conditions: Lower Extremity Muscle Strength

Summary: this is a pilot trial of a 16-week physical activity and power training program among 30 veterans/arm with advanced chronic kidney disease. the trial aims to test whether the program is tolerable to veterans.

this will be a randomized controlled pilot trial of a 16-week physical activity and power training intervention trial among 30 pre-frail veterans with stage 3b-5 chronic kidney disease. the intervention will contain in-center and at-home components. it will lay the foundation for a large-scale future randomized controlled efficacy trial aimed to reduce frailty risk among veterans with advanced chronic kidney disease. 30 other veterans will be part of an attention control. the outcomes of this pilot trial are feasibility, acceptability, and fidelity. each of these outcomes will be measured using quantitative surveys and data review as well as qualitative assessments among veterans at trial close. as this is a pilot feasibility trial, it is intentionally not powered to detect whether the intervention has a significant effect on physical activity frequency, muscle strength, or physical frailty.
