In 2012, NFL star running back Chris Johnson challenged multi-World and Olympic Champion Sprinter Usain Bolt to race in a 40yd dash; that ultimately never happened. This article explores a theoretical matchup.
In response to Ken Jakalski’s article “A Farewell to Arms,” what readers must be made aware of is the basic lever physics of arm action and then surmise the significance of this when considering the role of the arms in the realm of sprinting.
Bolt managed the rounds beautifully by essentially just running fast enough to win each one and automatically qualify for the final.
