- •
In both walking and running, the vertical COM displacements decreased with an increase in speed.
- •
The muscle activity of lower extremity was smaller in walking than that in running at speeds below the PTS.
- •
The muscle activity of lower extremity was larger in walking than that in running at speeds beyond the PTS.
- •
The boost in energy consumption for walking beyond the PTS may be attributed to the activation of lower-extremity muscles.
