This is an example of a client who contacted us wanting to improve her 5 and 10k times. We evaluated her running pattern and jump landing from a 12inch platform. Her running kinematics were quite good however inactivation of her gluteals in stance phase of running were made very apparent when evaluating jump landing. On jump landing the shift in midline and pelvic drop our quite apparent. We gave her a programme to engage her gluteals and develop endurance in these muscles. This will help keep centre of mass high to help her stride length and make her more efficient. Increase stride length and stride frequency = improve race time! Simple!
