Corticospinal activation of the quadriceps in athletes with <jats:styled-content style=\"fixed-case\">AKP<\/jats:styled-content> has not yet been investigated, but is important in guiding efficacious treatment. This cross\u2010sectional study assessed corticospinal excitability (<jats:styled-content style=\"fixed-case\">CSE<\/jats:styled-content>) of the quadriceps in jumping athletes using transcranial magnetic stimulation (<jats:styled-content style=\"fixed-case\">TMS<\/jats:styled-content>).
