Does symmetry matter for speed? Study finds Usain Bolt may have asymmetrical running gait

(Southern Methodist University) Researchers from Southern Methodist University, Dallas, say world champion sprinter Usain Bolt may have an asymmetrical running gait, throwing into question whether symmetry matters for speed. Using a 'two-mass' model for assessing patterns of ground-force application suggests Bolt's right and left legs may perform differently, defying scientific assumptions that asymmetry hinders performance. Unexpected and potentially significant asymmetry in the fastest human r...
