Double Olympic champion Rebecca Adlington will begin a mentoring role with British Swimming in January.
Adlington is a four-time Olympic medallist, having won a memorable gold medal double in the 400m and 800m freestyle in Beijing in 2008, before claiming bronze medals in the same events in London last year.
Head coach Bill Furniss, who guided Adlington to her medals, has spoken before about utilising her experience of competing at the highest level and he has now confirmed that she will start working with junior swimmers in an advisory capacity next year.
"Rebecca will be working as a mentor," said Furniss. "She has already done a session with the coaches.
"It will be with a selected group of juniors. She has experience and, importantly, she gets it. We want to use that expertise."
The 24-year-old Adlington announced her retirement from all competitive swimming in February of this year.
Jamieson to take on Gyurta
Furniss was speaking ahead of the European Short-Course Championships, which start in Herning, Denmark, on Thursday.
Olympic 200 metres breaststroke silver medallist Michael Jamieson will be competing and he will again lock horns with Daniel Gyurta, who won the gold in London.
Jamieson said: "I expect Olympic champion Daniel Gyurta to be at the front again, as he's been so dominant in the 200m event over the past few years.
"It will definitely take a British record and a big best time for me to challenge for that top spot but that's what all of the hard work in training is aimed at."
