Overview
- Sinner underwent hospital checks in early June that reportedly found no specific pathology after his collapse at Roland Garros, and he has since resumed full training.
- Photographs from mid-June showed Sinner wearing a small adhesive continuous glucose monitor, a device that records blood-sugar trends in real time to spot drops during prolonged exertion.
- His team is using the CGM as a diagnostic and preventive tool to test whether exercise‑induced glucose falls contributed to sudden energy loss, and to inform feeding and hydration plans.
- Sinner flew to London on Thursday to start grass preparations and will use the Armani Tennis Classic at the Hurlingham Club (June 23–27) as his only on‑grass rehearsal before Wimbledon.
- The move reflects a wider trend of elite players using CGMs to fine‑tune performance, and it could change how Sinner manages in‑match nutrition and recovery to reduce the risk of repeat incidents.
