The New York-native held dual citizenship for Britain and the United States and competed for Team GB at the 2006, 2010 and 2018 Winter Olympic Games at Turin, Vancouver and Pyeongchang, respectively. 

"Rosen will go down as perhaps Britain's greatest luge athlete," said Team GB in a statement.

"In addition to his remarkable skills on the ice, Rosen was regarded as one of the warmest and friendliest individuals and will be sorely missed by those who knew him."

"The British Olympic Association is deeply saddened to hear of the passing of Adam 'AJ' Rosen," British Olympic Association chief executive Andy Anson said.

"A three-time Olympian competing in luge, AJ was often the sole representative from his sport for Team GB, but his infectious smile and warm personality made him a highly valued member of any Team GB delegation he was a part of.

"Our thoughts and condolences go to AJ's family, loved ones and his sporting friends and colleagues."

Rosen had first become attracted to luge after watching the 1994 Winter Olympics in LIllehammer on television in his New Rochelle home when he was nine years old.

He finished 16th in the men's single event at Turin 2006 before recording Britain's best-ever result at a Luge World Cup, finishing sixth in Calgary in 2009.

Rosen replicated his 2006 finish at Vancouver 2010, although he did not qualify for the next edition in Sochi in 2014.

He qualified for his third and final Winter Olympics when he was selected for the 2018 Games in Pyeongchang, where he finished 22nd.

He retired from the sport later that same year.

"All of our thoughts are with AJ's family and friends at this difficult time," said International Luge Federation (FIL) President Einars Fogelis.

"The whole FIL family will miss AJ Rosen very much and will always remember him fondly".
