The programme is part of the I Am Team GB festival of sport which is encouraging people across the nation to be inspired to get active.
There will be events across the country taking place on the weekend of August 14 and 15, including a 5k Your Way event at the University.
Matt said: “I would encourage people to sign up and give it a go. If you have the opportunity always go along and try it because you don’t know what is going to be the sport that you can enjoy and get involved in.
“It’s not always about making the Olympians of the future, for me that’s always a bonus, but having a sport for every kid to be involved in is the legacy of the Olympics and for me that is the great thing about the Olympics…
“…It showcases all these different sports and I am a big believer there is a sport out there for everyone.”
The Football Unites launch event began in true Olympic fashion, as participants enjoyed an Opening Ceremony which featured a talk from the decorated Team GB rower.
During the day, children enjoyed a variety of games and activities, all played with a ball.
In one event, Matt Langridge swapped his oars for a pair of goalkeeper gloves, as children were tasked with scoring a penalty kick against the Olympian.
Football Unites is being delivered by the University of Hull and Hull Sport, in partnership with Team GB, to increase participation and opportunities for young people in sport.
Dan Smith, Sport Development Officer at the University of Hull, said: “The aim is to get as many kids involved as we can and playing football.
“To have Matt down with the children has been really special. My role is to get as many people involved and in sport as I can and what better way to do it than with children. It has been a really great day.”
The event finished in suitable fashion with a Closing Ceremony, and children had the chance to have their photo taken with Matt and his collection of Olympic medals.
