Doping Scandal Rocks Paralympic History

Russian Para-biathlete Nikolay Polukhin has been formally stripped of his Sochi 2014 Winter Paralympics medals after an 11-year investigation confirmed anti-doping violations. The International Paralympic Committee (IPC) concluded that Polukhin's urine samples were tampered with during the Games, part of a wider state-sponsored doping program.

Forensic Evidence Unveiled

• DNA analysis proved Polukhin provided 'clean' urine samples that were later swapped to mask trimetazidine (TMZ), a banned substance that enhances endurance by increasing blood flow to the heart.
• Forensic experts noted physical tampering on sample bottles, including scratch marks and a urine residue tooth mark, indicating the bottles were reopened and resealed.
• The IPC tribunal ruled the athlete's actions "significantly undermined the integrity" of the competition.

Consequences and Fallout

Polukhin forfeits:

• Gold in Men’s Para-biathlon 15km Visually Impaired
• Silver in 7.5km and 12.5km events

His appeal to the Court of Arbitration for Sport (CAS) was withdrawn after he failed to pay required fees. The IPC confirmed this case concludes all investigations into Sochi 2014 doping violations.

Broader Context: Russia’s Doping Era

• The World Anti-Doping Agency (WADA) exposed a state-sponsored program (2012–2015) where labs swapped 'dirty' samples with 'clean' ones.
• Russia faced Olympic/Paralympic bans from 2015–2022, competing under neutral flags.
• Only two athletes were sanctioned from Sochi 2014: Polukhin and Italian Para ice hockey player Igor Stella.

What’s Next?

The case has been forwarded to:

• International Ski and Snowboarding Federation (FIS)
• International Biathlon Union (IBU) for potential further sanctions.

The Sochi 2014 Games remain a stark reminder of the consequences of institutionalized doping.
