Jannik Sinner has resumed his preparations for Wimbledon following a series of medical evaluations at the San Raffaele Hospital in Milan. According to reports from the facility, the tennis star underwent heart-related diagnostics, including an electrocardiogram and MRI, after experiencing physical distress during his match against Juan Manuel Cerundolo at the Roland Garros tournament. His medical team has cleared him to return to training in Monte Carlo, with no immediate plans for further competitive warm-up events.
Why were medical checks necessary after the French Open?
The decision to conduct clinical tests followed a mid-match physical collapse during the French Open. While initial speculation pointed toward the high temperatures in Paris, Sinner explicitly rejected the heat as the cause during his post-match press conference. According to Sinner, the symptoms were a reminder that professional athletes are not “robots” and that the cumulative fatigue of a rigorous tournament schedule can manifest unexpectedly. The medical team at San Raffaele performed a battery of tests, including an echocardiogram and a Holter monitor, to ensure there were no underlying cardiac issues.

Elite tennis players often utilize Holter monitoring—a portable device that records heart activity for 24 to 48 hours—to distinguish between standard athletic heart adaptations and genuine medical irregularities during high-intensity recovery phases.
How does Sinner’s recovery impact his Wimbledon campaign?
Sinner has opted for a conservative recovery path, choosing to forgo any grass-court tournaments leading up to Wimbledon. This strategy prioritizes long-term physical conditioning over immediate match practice. According to his team’s assessment, the priority is to reach full recovery before the start of the Grand Slam. By returning to his training base in Monte Carlo, Sinner is focusing on a structured load-management plan rather than rushing back into the high-stress environment of competitive play.
Are elite tennis players facing an unsustainable schedule?
The incident highlights a growing conversation regarding the physical demands of the modern ATP tour. Sinner’s admission that he had been playing significantly in recent months mirrors concerns raised by other top-tier athletes regarding the density of the calendar. Unlike the traditional approach of playing lead-up tournaments to “find rhythm” on grass, Sinner’s choice to skip these events suggests a shift toward data-driven recovery. This approach prioritizes biological readiness over the traditional “more matches equals better form” philosophy.

The “human as a machine” metaphor is increasingly challenged in modern sports science. Studies into the “overtraining syndrome” suggest that even minor physiological dips, often ignored by players, can lead to systemic failures if not managed with clinical intervention.
