Hi Chris Hope you are well!Hope it's okay to ask this question here - I have a female athlete that is tilting her head left then right when she is running. In the 100 m hurdles she does not do that but in the 400 m hurdles she is breaking apart at the 150 then the head starts to tilt. Why is that? And also will the Vsit with all the different perturbations fix that? Thank you Chris
