^aTable reports median (IQR) reference (REF) and BioHarness (BH) respiratory rates, absolute (br·min-1) and relative (%) biases.

^bThe letters ^{r t R}= rest, transition, run; statistically significantly different compared to Phase One rest, transition, Run (P<.001 to P=.04). The letters ^{r t w c s v} = rest, transition, walk, cycle, sweep, vacuum; statistically significantly different compared to Phase Two rest, transition, walk, cycle, sweep, and vacuum (P<.001 to P=.02).

^cStatistically significantly different compared to reference measures (P<.001).
