Last Word on Point:Counterpoint: Artificial limbs do/do not make artificially fast running speeds possible.

摘要

to the editor: The present debate opposes coauthors of a recent study (4), with a narrow focus on swing time and vertical ground reaction force, the latter being known as an important mechanical parameter determining top running speed, but not the former, according to Weyand et al. (5). However, whether they both influence overall 400-m performance on the field, and how remains unknown, and makes any speculation such as that leading to the 12-s advantage (3) questionable.
