He was rushed to hospital, but never regained conciousness.
Speaking to the BBC, Becky and Ellie explained why they were now giving their backing to the defibrillator database campaign.
Ellie said: When someone is having a heart attack or cardiac arrest, it’s minutes that you’ve got to get a defibrillator on there before it’s too late.
"You need one as close by as you can really, so it’s good to know where all the nearest ones are."
Becky added: “If you don’t have access to them, they can’t be used.
"There are tens of thousands that are out there that aren’t registered, that just aren’t being used and people don’t know about them and it’s just a matter of minutes that will save a life.
"So it’s about trying to make people as aware as they can be about these things and hopefully a lot more lives can be saved going forward.”
Tributes poured in for Josh from the likes of Hucknall Town CC and the Nottinghamshire Premier League after the sad news of his death was announced last year.
And the sisters feel backing this campaign is helping them come to terms with their loss.
Ellie said: "I feel like I’m finally starting come out the other side now, which is nice.
"Life is just so short you’ve got to live every day and be happy.
"So that’s the approach I’m taking this year, just to live every day, be happy, make sure every day is fun, enjoyable, because you just don’t know when any day could be your last.”
Becky added: “Josh wouldn’t want me to stop because of what’s happened.
"He was always so supported of our careers and what we did.
"He’ll always be a massive part of us and I think, if anything, it’s continuing to do what you love as well for him because he would want us to.”
