In a recent interview with El Confidencial, Rafael Nadal's long-time doctor, Angel Ruiz Cotorro commented on Nadal's evolution, both on and off court.
'Rafa has been doing things differently for a couple of years,' he said. 'Now he is taking control over many details that he used to approach in a different way in his youth. He is very disciplined in terms of preparation and diet, for example.
He also cares about knowing how he needs to practice, how he needs to put it in competition. Little details mark a difference when you have a certain age. We have been always doing it, but more in the last years.' Nadal had success in 2017 when he turned 31, which says a lot about his longevity.
About this, Dr. Cotorro said, 'Injuries are part of the sport. You can try to prevent, but things do not always go as you want. Rafa knows it. Last year Rafa played 18 tournaments. It's absolutely necessary to play so many tournaments to be the world no.
1. By playing fewer tournaments, you can't be the world no. 1 Rafa always wants the best from himself, and in the 30s he keeps this discipline to be at the top.' ALSO READ: Eugenie Bouchard losing sponsors due to bad results .
