British Cycling has introduced a new mandatory cardiac screening policy as awareness grows of the risks faced by sportspeople.
Every rider, from academy to elite level, will have an annual electrocardiogram (ECG) and heart scan to determine if they are at increased risk of suffering sudden cardiac arrest.
In some cases athletes could be advised to retire if it is determined they would risk death by continuing to compete.
Some experts think athletes are three times more likely than non-athletes to suffer sudden cardiac arrest.
The screening at British Cycling is being carried out and paid for by a team from Liverpool John Moores University as part of their research into cardiac health among athletic people.
Professor John Somauroo, a sport and exercise cardiologist, said: “We know there are high profile athletes having cardiac arrests.
“But equally unfortunately there are about current thinking around 12 young athletes between the ages of 14 and 35 per week dropping dead in Britain.
“And in fact that’s relatively old data and the newer data suggests that it’s at least 20 young people if not even higher that are having those events per week.”
He added: “If you were to have a bus load of kids crashing into a low bridge every week and half the children were killed. They’d do something about the bridges or the bus routes.”
