Running economy (RE) has a strong relationship with running performance. Running biomechanics are a determining factor of RE.
The studies propose that the following are beneficial for running efficiency
- a preferred stride length range (relaxed running)
- lower vertical oscillation (bouncing), strongly related to greater leg stiffness;
- low lower limb moment of inertia (related strongly with the GCT-%)
- larger stride angles;
- less leg extension at toe-off;
- alignment of the ground reaction force and leg axis during propulsion; (related to braking)
- maintaining arm swing
- low thigh antagonist–agonist muscular coactivation; and
- low activation of lower limb muscles during propulsion.
