Context: To determine the relationship between running form to both energy cost and performance. Five form categories: vertical oscillation, braking, posture, stride parameters, and lower limb angles. 97 endurance runners.


Results:

Regression analysis found three variables that explained 39% of running energy cost variability:

  • pelvis vertical oscillation during ground contact,

  • minimum knee joint angle during ground contact, and

  • minimum horizontal pelvis velocity.


Four variables explain 31% of the variability in performance:

  • minimum horizontal pelvis velocity,

  • shank(shin) touchdown angle,

  • duty factor (the fraction of the stride cycle that was ground contact time, and

  • trunk forward lean (waist to shoulders lean forward vs vertical).


Conclusions:

  • This study provides novel and robust evidence that technique explains a substantial proportion of the variance in energy cost and performance.

  • It recommends runners are attentive to stride parameters and lower limb angles to optimize pelvis movement and enhance performance.
