Olympic silver medallist Michael Jamieson wants to end a "fantastic" personal year with a podium finish at the World Championships in Turkey.
Jamieson, 24, has also backed his team-mates to recover from an otherwise "disappointing" London 2012 Olympics.
"We would love to have won more medals [in London] as a team, so there is that sense of disappointment," Jamieson told BBC Sport.
"But everyone wants to move on and there's lots of potential in the team."
Jamieson continued: "The next season has already started and we'll look to try to get back on the horse and win some more medals in the upcoming majors.
"Being one of the oldest now I feel a sense of responsibility to step up and lead the team by example."
The World Short Course Championships, based on 25m lengths rather than the 50m distance used at the Olympics, are usually regarded as being of secondary importance to the long course versions.
However, Great Britain are sending a strong squad which includes London Olympians Francesca Halsall, Elizabeth Simmonds, Hannah Miley and Andrew Willis.
With UK Sport set to reveal how much funding all Olympic and Paralympic sports will receive through to the Rio 2016 Games later in the month, Istanbul is seen as a final chance for British Swimming to send out a positive message after the fall-out from double London 2012 bronze medallist Rebecca Adlington calling the sport an "absolute mess".
Although many of the swimmers took time away from the sport after the London Games and are still building their fitness for the new season, acting head coach David McNulty believes there are several strong medal contenders.
"It is very early in the season but we certainly have four or five who have been to this level before and won medals," McNulty told BBC Sport.
"If we set up and do what we're capable of then we could [win medals] - it will be tough as it always is at a Worlds, but I think one or two medals would be a great start to the new four-year [Olympic] campaign."
Miley, a 2011 World Championship silver medallist, finished a surprise fifth in her favoured 400m individual medley event in London, but showed an impressive return to form at the recent European Short Course Championships in France, winning a gold and two silver medals.
"It would have been lovely to come away with a medal [in London] but I think that every athlete wants the same and I can't sit there and sulk because it didn't happen for me," Miley told BBC Sport.
"It's motivation and these Worlds [in Istanbul] will give me another chance to race against the likes of Ye Shiwen [China's double Olympic champion], which will be good experience ahead of next year's long course World Championships in Barcelona."
