Data collection process: This dataset includes continuously measured walking biomechanics collected using three-dimensional motion capture and gas exchanges of 18 healthy participants (9 male/9 female, mean +/- standard deviation age 24.8 +/- 3.3 years, height 1.71 +/- 0.81 meter, weight 65.9 +/- 8.1 kilogram). Walking biomechanics were recorded during four different self-paced speeds (comfortable, very slow, slow, fast) in randomized order and ...
