Great Britain's Jessica Ennis-Hill has called for more support for athletes who are returning to the highest levels of sport after having children. 

The 34 year-old became Olympic heptathlon champion at London 2012 and won silver four years later in Rio. 

In 2014 she gave birth to her son Reggie, and a year later went on to win a third world title. 

"I think it's something we still need to work on and support more women coming back into sport after having their children.

"It's a fantastic time and these women that do it, it's an incredible thing to do. It's a tough challenge but we are so motivated after having our children to come back and be even better than we were before, so why not support these athletes as much as we can."

The 2010 European champion also said she has seen a huge growth in women's sport. 

"I think it's constantly changing and evolving and we're having more opportunities. That barrier and that mid-ground is coming closer to an equal. I've definitely seen it change and I hope to see it continue to change in future years."
