Summary

This study examined 47 female football players to see if those with Morton toe (a longer second toe) have different muscle and jumping abilities compared to those with normal feet. Researchers measured muscle contraction speed and reactive strength during jumps. The goal was to understand if this common foot shape is linked to athletic performance.
