CI, Confidence interval; HR, heart rate; PAEE, physical activity energy expenditure; IQR, interquartile range; REE, resting energy expenditure; TEE, total energy expenditure; SHR, sleeping heart rate.
Data are mean (95% CI) unless otherwise indicated. HR economy is defined as walking distance per HR above rest, m/beat.
