Fig. 3
The left column is the example of the behavior of BCoM energies during treadmill walking (without poles) at 3 km h−1, at the pre- and post-training moments. Top panel PE and KE, and TE = PE + KE, lower panel R%(t) indicating the conversion percentage of the pendulum mechanism during the step time cycle. Divided lines FW group and continuous lines NW group, left and right side of the figure of the BCoM energies represent the pre- and post-training moment, respectively. In the right column are the results of the Wint_legs, Wint_trunk, and Wint_arms of FW and NW groups in pre- and post-training moments, in the different speeds (results are in mean values, for more information see Table 4)
