Table 1. Results for 12 subjects showing cumulative run times in minutes (min) and seconds (s), heart rate (HR) variation coefficient, the exponential time constant for the increase in heart rate, and the number of steps taken during the run for adaptive and sham condition. All values are expressed as mean (±SD) as applicable.
