The achievement of significant results at a competitive level requires an early approach to the practice of discipline, although in almost every sport the competitive maturity ordinarily coincides with the age of majority: what you lose in terms of reflexes readiness and physical energies' resilience, you gain, in fact, in terms of himself managing during agonistic trance. Now, in the face of claims of performance more and more higher, it’s undeniable how the access to doping by underage athletes also increases. This is a question that needs a careful thought, considering the specific condition of minors: a question that doesn’t seem to receive the attention due at a regulatory level (state or sports rule). It being understood, in fact, the unavoidable disqualification of results ex officio of the result achieved in altered states, the system of penalties provided for underage athletes doesn’t seem to change much if compared to that one put in place for adult athletes. All this reveals a paradox, in my opinion, little studied: I wonder, in fact, how much is taken into account the intrinsic legal incapacity of minors. Not only I wonder which legal relevance can be recognized at any consent provided by the minor: better, may the given consent constitute a condition of culpability? Which, instead, the responsibility profiles of involved adults?
