The first is almost correct. It should be, "Some athletes have taken drug tests to prove they are not on steroids." That is, "have taken" is the correct form, but it should also be "drug tests" rather than "drugs tests". "Have taken" is the correct form because "have" is the plural form, and "athletes" is plural. The singular form is "has taken", so it would be correct to say "One athlete has taken drug tests to prove he is not on steroids." Always use the past participle "taken" and not the simple past tense "took" in forms that use a form of the auxiliary verb "have": have taken, had taken, has taken, would have taken, and so on.
