On 6 January 2024, the athlete provided a sample during an out-of-competition anti-doping control performed by the ITA. The analysis of the sample by a World Anti-Doping Agency (WADA)-accredited laboratory returned an adverse analytical finding¹ for metenolone and its metabolites.
Metenolone is prohibited under the WADA Prohibited List as S1.1 Anabolic Androgenic Steroids. It is classified as a non-specified substance and prohibited at all times (in- and out-of-competition). Metenolone stimulates muscle growth and assists the recovery after strenuous effort.
Following the results management process conducted by the ITA, the ITA submitted the matter for adjudication to CAS ADD.
On 27 August 2025, and further to a hearing process during which the ITA represented ISA, CAS ADD found that the athlete had committed the ADRV and imposed a 16-month period of ineligibility.
Considering that Mr Tudela Chiozza was under a provisional suspension during the results management proceedings, the time served under provisional suspension was credited against the total period of sixteen months suspension and consequently, the period of ineligibility ran until 16 August 2025. All the results obtained by the athlete from the date of sample collection, i.e. 6 January 2024 until 16 August 2025 are disqualified, with all resulting consequences, including forfeiture of any medals, points and prizes, except for 2024 ISA World Surfing Games, which took place between 23 February and 3 March 2024².
Parties with a right of appeal have not challenged the CAS ADD decision before the appeal division of the Court of Arbitration for Sport in accordance with article 13.2 of the ISA anti-doping rules (ISA ADR) and the decision is considered final.
The ITA will not comment further on this case.
¹ A report from a WADA-accredited laboratory that, consistent with the International Standard for Laboratories, establishes in a sample the presence of a prohibited substance or its metabolites or markers or evidence of the use of a prohibited method.
² Pursuant to article 7.4.1 of the ISA anti-doping rules, an athlete has the right to ask for the lifting of the provisional suspension and provided the athlete meets specific conditions, the provisional suspension may be lifted allowing the athlete to participate in competitions pending the results management of his case. Following Mr. Tudela Chiozza’s request, his provisional suspension was temporarily lifted and he was allowed to participate in the 2024 ISA World Surfing Games, where he placed 37th. The provisional suspension was reimposed on 6 May 2024 when the ITA found that the conditions for the lifting of the provisional suspension were no longer met.
