Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in repeated chair rise time | Baseline to end of study, approximately 14 weeks | Chair stand test where participants will perform a chair rise movement for five repetitions. The series of 5 repetitions will be timed and measured in seconds. |
| Change in plasma protein levels reflective of biological age | Baseline, week 12 | Blood samples will be obtained at baseline and at 12 weeks. The concentration of target proteins (pg/mL) in the plasma will be measured and compared between baseline and week 12. |
| Change in expression of senescence-related genes in blood cells | Baseline, week 12 | Blood samples will be obtained at baseline and at 12 weeks. The expression of senescence-related genes (arbitrary units) will be measured in immune cells isolated from whole blood and compared between baseline and week 12. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in Self-reported Physical Function | Baseline, week 12 | Measured using the Physical Component Scale (PCS) from the 12-Item short form general health survey (SF-12). |
| Change in self-assessment of well-being | Baseline, week 12 | Measured using a linear analogue self-assessment scale of well-being from 0 (as bad as it can be) to 10 (as good as it can be) of mental, physical, emotional, and spiritual well-being, level of social activity, and overall quality of life during the past week |
| Change in Performance-based Physical Function | Baseline, week 12 | Measured using the timed up-and-go test (seconds to complete). |
| Change in Mental Function | Baseline, week 12 | Measured using the Mental Component Scale (MCS) from the 12-Item short form general health survey (SF-12) |
