Weightlifter Rebekah Tiler refused to take part at the British Championships today after going on "strike" due to a lack of funding.
The 18-year-old competed at the Rio 2016 Olympics but did not appear for the under-69 kilograms event at the Ricoh Arena in Coventry.
"Sorry guys won't be at the British this year on strike till some funding is found," she tweeted.
"British Weightlifting, thanks for messing my life up."
Weightlifting was one of five Olympic sports to have its funding completely cut by UK Sport in December.
It was deemed that it is not a credible medal sport for Britain at the Tokyo 2020 Olympic Games.
Archery, badminton, fencing and table tennis also had their funding cut, as well as the Paralympic sports of goalball and wheelchair rugby.
Tiler was Britain's only female weightlifter to compete in Rio, finishing 10th.

She was fourth at the 2014 Commonwealth Games in Glasgow and at the 2016 European Championships in Førde in Norway.
British Weightlifting (BWL) said they could not support a women's team following the UK Sport decision.
"BWL no longer has the funds to support an elite squad of female lifters training for Tokyo 2020 Olympic Games and the major Championships leading up to it, despite the possibility of winning a medal at the Games," a statement sent to the BBC said.
"Sport England continues to support BWL, although that funding is ring-fenced for the development of the sport and at grassroots level.
"A small budget from Sport England has been allocated to support the squad ahead of the Gold Coast 2018 Commonwealth Games.
"Irrespective of these circumstances, it has been a fantastic weekend at the British Weightlifting and Para Powerlifting Championships, with multiple British records being broken and many athletes beating their personal bests.
"BWL are delighted to see a strength in depth across a range of categories and we are feeling extremely positive for the future of all our athlete."
Tiler has also said that she is now living in accommodation which is not up to standard.
A UK Sport spokesperson said: "We have had to make some tough decisions around investment for the Tokyo cycle.
"We did not take these decisions lightly and are acutely aware of the impact they have on sports, athletes and support personnel.
"We acknowledge the progress and commitment of the sports and athletes affected.
"This is just a matter of us having to prioritise available resources towards those with the strongest medal potential as we focus on our aspirational goal to deliver more medals and medallists at Tokyo 2020.
"This is the first time that we have been unable to support every sport that has athletes with the potential to deliver medals at the next Games.
"To support those affected, we put in place a comprehensive transition and support package and have worked closely with these sports to help staff and athletes move away from dependency on UK Sport funding.
"In the meantime, we will still be supporting more than 30 sports with the collective potential to win more medals in Tokyo 2020, in a way that will make the nation very proud once again."
