This is a pilot trial of a 16-week physical activity and power training program among up to 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 up to 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. Up to 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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Power training and monitored physical activity | Experimental | This is a 16-week power-training and physical activity-focused intervention that contains in-center and at-home components and motivational coaching. Participants will meet 2-3 times per week for the in-center power training. Participants will also be asked to wear accelerometers at home in order for their physical activity frequency to be measured. |
|
| Attention control | Active Comparator | This will be the attention control arm that will involve receipt of a physical activity education booklet, use of an accelerometer, and weekly check-in calls. No power training or motivational coaching will be delivered. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Pro-social Power training Activity for Aging and Well-being with Chronic Kidney Disease | Behavioral | This is a 16-week power-training and physical activity-focused intervention that contains group in-center and individual at-home components and motivational coaching. Participants will meet 2-3 times per week for the in-center power training. Participants will also be asked to wear accelerometers at home in order for their physical activity frequency to be measured. |
| Measure | Description | Time Frame |
|---|---|---|
| Feasibility, as measured by the questionnaire, the Feasibility of Intervention Measure | This will be a brief questionnaire known as the Feasibility of Intervention Measure, that asks participants whether the intervention seems doable to them. There are four questions, and participants are asked to rate intervention feasibility from a scale of 1 (Strongly Disagree) to 5 (Strongly Agree). Scores range from 1-5 and are calculated as the mean of all scores. Higher scores indicate greater perceived feasibility. This will not be aggregated with any other measure. | 4 months |
| Feasibility, as measured by a numerical percentage of all participants who consented out of those eligible | This will be a numeric percentage of participants who consent for the pilot trial out of all eligible participants in Aim 1. This will not be aggregated with any other measure. | 4 months |
| Feasibility, as measured by a qualitative description of participants' reasons for declining | This will be a qualitative description of potential participants' reasons for declining, if applicable. This will not be aggregated with any other measure. | 4 months |

| Measure | Description | Time Frame |
|---|---|---|
| Acceptability, as measured by the questionnaire, the Acceptability of Intervention Measure | This will be a brief questionnaire known as the Acceptability of Intervention Measure, that asks participants whether the intervention seems acceptable and/or enjoyable to them. There are four questions, and participants are asked to rate intervention acceptability from a scale of 1 (Strongly Disagree) to 5 (Strongly Agree). Scores range from 1-5 and are calculated as the mean of all scores. Higher scores indicate greater perceived acceptability. This will not be aggregated with any other measure. |
Inclusion Criteria:
Participant's nephrologist and/or primary care physician agree that participant may enroll in trial
Participants classified as pre-frail per Fried Frailty phenotype due to slowness (time taken to walk 15 feet is greater than 6 seconds) in Aim 1, OR who report 'YES' to any of the following:

Veterans will be randomized to either the intervention to an attention control. Randomization will be performed by the biostatistician. Veterans will be randomized to the intervention group (or to the attention control) using a block randomization scheme with randomly selected block sizes of 2, 4, and 6. Participants in the attention control will receive educational resources regarding the benefits of physical activity prior to intervention start (A brief document related to the importance of physical activity in kidney disease and handouts from the Center for Disease Control's recommendations for physical activity for older adults). Participants in the attention control may also receive a weekly phone call on general health.

All research assistants and biostatistics personnel will be masked to each participant's assignment. Participants and study staff are unaware of group allocation at the time of recruitment and baseline assessments because randomization is performed after participants have completed baseline assessments. However, there is no blinding to group allocation after randomization.

| Attention Control for Pro-social Power training Activity for Aging and Well-being with Chronic Kidney Disease | Behavioral | This will be the attention control arm that will involve receipt of a physical activity education booklet, use of an accelerometer, and weekly check-in calls. No power training or motivational coaching will be delivered. |

| Acceptability, as measured by participants' qualitative descriptions of reasons for intervention enjoyability, if applicable | This will be a qualitative description of participants' reasons they found the intervention enjoyable to participate in, if applicable. This will not be aggregated with any other measure. | 4 months |
| Fidelity, as measured by the percentage of sessions participants attended out of all possible sessions | This will be a percentage, measured by the number of sessions a participant attended out of all possible sessions that could have have been attended. This will not be aggregated with any other measure. | 4 months |
| Fidelity, as measured by accelerometer step count during prior week | This will be the step count during the prior week recorded on an accelerometer worn by each participant. This will be measured at each of the following time points: one, two, and three months after intervention close. That is to say, this will be measured at 5 months, 6 months, and 7 months after intervention start. This will not be aggregated with any other measure. | 5 months, 6 months, and 7 months |
| Fidelity, as measured by the questionnaire, the Physical Activity Scale for the Elderly | This will be measured using the questionnaire, the Physical Activity Scale for the Elderly, a ten-item questionnaire that inquires about the frequency, duration, and intensity of physical activity during the prior week. Scores range from 0-793, with higher scores indicating completion of more frequent and/or intense physical activity. This will be measured at each of the following time points: one, two, and three months after intervention close. That is to say, this will be measured at 5 months, 6 months, and 7 months after intervention start. This will not be aggregated with any other measure. | 5 months, 6 months, and 7 months |
