The rules will apply to women in track events from 400m up to the mile and require that athletes have to keep their testosterone levels below a prescribed amount “for at least six months prior to competing”.
Sheria hizo zitatumika kwa wanawake katika mashindano ya mbio kutoka mita 400 hadi maili na zinahitaji kwamba wanariadha wanapaswa kuweka viwango vyao vya testosterone chini ya kiwango kilichowekwa "kwa angalau miezi sita kabla ya kushindana".
