Result of the cost of transport (C, left vertical axis) and Recovery (R, right vertical axis) at different walking speeds. Results are presented as mean, white and black circles with continuous lines and light gray square and dark gray square with continuous lines represent C values from the FW group and NW group in pre- and post-training moments, respectively. White and black diamond with dotted lines and light gray and dark gray triangles with dotted lines represent R values from the FW group and NW group in pre-and post-training moments, respectively. The white and black arrows represent the optimal speed (OPT that is the speed at the minimal C of walking) of FW group (from pre- to post-training was from 3.50 to 4.04 km h−1 ), and the light gray and dark gray arrows represents the OPT of NW group (from pre- to post-training was from 3.81 to 4.29 km h−1). * Symbol between white and black arrows united by the continuous indicator and the * between light gray and dark gray arrows united by the indicator with dotted line represents significant difference (p < 0.05) in factor time in OPT of FW and NW group (from pre to post-training), respectively
