Symmetrical knees predict sprinting speed

Lower Body Symmetry and Running Performance in Elite Jamaican Track and Field Athletes

In a study of degree of lower body symmetry in 73 elite Jamaican track and field athletes we show that both their knees and ankles (but not their feet) are – on average – significantly more symmetrical than those of 116 similarly aged controls from the rural Jamaican countryside. Within the elite athletes, events ranged from the 100 to the 800m, and knee and ankle asymmetry was lower for those running the 100m dashes than those running the longer events with turns. Nevertheless, across all events those with more symmetrical knees and ankles (but not feet) had better results compared to international standards. Regression models considering lower body symmetry combined with gender, age and weight explain 27 to 28% of the variation in performance among athletes, with symmetry related to about 5% of this variation. Within 100m sprinters, the results suggest that those with more symmetrical knees and ankles ran faster.  Altogether, our work confirms earlier findings that knee and probably ankle symmetry are positively associated with sprinting performance, while extending these findings to elite athletes.

Verräterischer Hüftschwung

Wie jemand tanzt, sagt eine Menge über seine Persönlichkeit aus.

Vom Stammestanz der Massai in Kenia bis zur Techno- Party im angesagten Berliner Club – getanzt wird in allen Kulturen. Die rhythmischen Bewegungen zur Musik machen nicht nur Spaß, sie erfüllen auch viele wichtige Aufgaben: Götter beschwören, Regen bringen, Gegner beeindrucken, Gemeinschaft und Kampfesgeist stärken. Die aus evolutionärer Sicht wohl wichtigste Funktion aber dürfte die Balz sein (...) >>
