Premier League referee Chris Foy believes elite referees have never been better prepared going into the start of a season.
He says the appliance of science is enabling the group to cope with the demands of the modern game.
Intense fitness programmes and psychology are just some of the tools used to further their education in a billion-pound industry.
Foy, who has 23 years refereeing experience, said: "The game has never been as fast and we have got to keep pace.
"We are trying to do that. Two sports scientists work alongside us and every week they e-mail a training programme, which we have to adhere to.
"We meet as a team of referees every two weeks. That entails physical training and mental stimulation.
"We talk to sports psychologists, who tell us how we can look after ourselves better.
"We know we have to be in peak condition and referees at this level have never been fitter.
"While we might not be a young as the players, we are more accomplished at reading the game today. When someone makes a 70-yard pass more often than not we are able to judge it correctly."
