Heart rate control using first- and second order models during treadmill exercise

[Abstract]=36 data sets from 10 participants during 2 series of heart rate control tests implemented by the treadmill. Each data set mainly consists of the target heart rate, the measured heart rate, and the commanded treadmill speed. For details about the test protocol and the outcome definitions, please refer to the article: H. Wang and K. J. Hunt, "Heart rate control using first- and second order models during treadmill exercise," Systems Science & Control Engineering, vol. 9, no. 1, pp. 651–662, 2021. https://doi.org/10.1080/21642583.2021.1976304.
