Jannik Sinner follows method used by Novak Djokovic to further understand French Open struggles

But the ATP number one enters the prestigious event with a big question mark over his fitness, having really struggled in that area at the French Open.

Sinner failed to deal with the heat as he suffered a second round exit in Paris, which represents his most recent appearance on the court.

He is, however, now taking concrete steps in order to further understand the reasons behind his issues at the French Open.

How concerned are you about Jannik Sinner’s physical issues going forward in his career?

As reported by La Gazzetta dello Sport, Sinner is currently practising with a glucose sensor on his left arm.

It is part of the monitoring procedure he is following after tests at San Raffaele Hospital, with his team eager to understand how his blood sugar levels function.

If necessary, doctors and nutritionists can then intervene and adjust Sinner’s diet accordingly to prevent his energy from running low, as it did in the French capital.

Notably, legendary tennis figure Novak Djokovic has previously adopted the same method in order to monitor his blood sugar levels.

And that is undoubtedly significant given that the Serbian is still competing at the very highest level at the age of 39.

Incidentally, after his French Open disappointment, Sinner is not playing an event before Wimbledon, just like Djokovic.

And he will be joined at the tournament by several high-profile names, with American ace Ben Shelton the latest to be announced alongside Jiri Lehecka.

Also participating in the exhibition are Casper Ruud, Cam Norrie, Stan Wawrinka and French Open finalist Flavio Cobolli among others, including iconic figures Flavia Pennetta and Michael Chang.
