Jannik Sinner Takes Proactive Approach to Heat-Related Issues

Jannik Sinner, the world No. 1 and defending Wimbledon champion, has taken proactive steps to address the heat-related issues that have affected him in recent matches. Speaking at an exhibition event in London, Sinner revealed that he has made changes to his practice routine to better prepare himself for hot conditions.

Understanding the Root of the Problem

Following his loss to Juan Manuel Cerúndolo at the French Open, Sinner underwent testing to understand the root of the problem. He explained that the testing helped him and his team to come to a conclusion and make necessary changes to his practice routine.

'We did some testing, we tried to understand what happened, we came to a conclusion which is very good. So we worked very much, we changed the work a little bit as well, trying to see how my body reacts in different conditions,' Sinner said.

Practicing in Warmer Conditions

Sinner has altered his practice routine to include warmer conditions, which he believes will help him prepare for the increasing heat in tennis tournaments. He plans to continue this approach in the future, recognizing that every tournament is getting warmer and warmer every year.

'Today, was no wind at all, so it was maybe even warmer, but it's good. That's exactly what I need, a good preparation before starting the tournament,' Sinner said.

Preparation for Wimbledon

Sinner believes that this preparation will help him ahead of Wimbledon, where temperatures are forecast to be lower. He has also had the opportunity to see how his game feels on grass ahead of his title defense.

'I felt quite good today,' Sinner said of playing on grass at the Hurlingham Club. 'I think this has been one of the best preparations I've had since a long time before a Grand Slam.'
