bpm = beats per minute; RPE = (Borg’s) Rating of Perceived Exertion (6 to 20 scale); RER Respiratory Exchange Ratio.
Note: “Pre-training” and “Post-training” were used for both groups to indicate pre- and post- testing; however, the control group did not walk-train.
* p < 0.05 compared with pre-training.
† p < 0.05 compared with the control group at each time point.
