Table 6.

The estimated levels of VO₂ based on the regression equations from Table 5 (model 1) and three levels of HR from walking commuting (means ± SD), coefficients of variation (CV), and the 95% confidence intervals (CI) for all values

Participant	Average of the lowest, middle and highest fifth of HR at field, and estimations of VO₂ based on these levels of HR, and the HR–VO₂ regression equations at day 1 and day 2
