Correlations Between PBMC Mitochondrial Bioenergetics (SRC, Max-OCR, and Basal-OCR) and Gait Speed in Older Adults
| SRC | Max-OCR | Basal-OCR | ||||
|---|---|---|---|---|---|---|
| Correlation | r | p Value | r | p Value | r | p Value |
| Pearson | .609 | .009 | .585 | .014 | .425 | .089 |
| Partial with age | .598 | .015 | .573 | .020 | .416 | .109 |
| Partial with BMI | .612 | .012 | .585 | .017 | .427 | .099 |
| Partial with gender | .538 | .032 | .505 | .046 | .328 | .216 |
Notes: N = 17. Partial correlations were done independently of one another. BMI = body mass index; OCR = oxygen consumption rate; PBMC = peripheral blood mononuclear cell; SRC = spare respiratory capacity.
