How China trains its diving stars of the future

China's state sports schools are training would-be divers from the age of four.

By the age of 12 they are training for seven hours a day, seven days a week.

Team GB's Tom Daley has previously labelled his Chinese rival Qiu Bo a 'robot', saying the Chinese work extremely hard.

He told The Guardian: "The Chinese have got a different way of working. They're taken out of school and away from their families.

"There's just this conveyor belt of Chinese divers and they work them until they break and then the next one comes along and trains. So it's completely different. I train five hours a day, six days a week, which is a lot. But the Chinese guys are maybe doing seven hours of training, and working so hard. But they don't have a life. I do. I'm not constantly thinking about diving."

Tallking about Bo, he added: "He's like a robot. Or he has been known to be like a robot. But pressure sometimes gets to him. You have to be able to dive as well as him to put pressure on him."
