Recently multiple sports teams and individual athletes have begun using CGM as a proxy for managing their real time blood glucose. This allows the athlete to have a real time fuel gauge and understand the parameters of both diet/nutrition and performance metrics. It has been understood that glucose levels are very individualized. 

One’s subjective “readiness” and performance outcomes are also very nuanced and can be optimized through the use of CGM. There’s a growing body of evidence that suggest that using CGM to guide both pre-and post performance fueling can help with optimizing “go time” and enhancing recovery.
