Evidence check: Glukose in the context of Sport

The question about glucose in the context of sport is relevant because glucose is a primary fuel during exercise. However, the provided contexts contain no direct studies or data linking glucose to sport performance. There are references to genes like FTO and MC4R that influence energy balance, but these relate to obesity risk, not specifically to glucose utilization during training. The evidence for personalized glucose optimization via genetic testing is weak. Practically, blood sugar management, carbohydrate timing, and individual tolerance are important. A continuous glucose monitor (CGM) can help understand personal responses to different foods, but genetic prediction remains limited. Safety note: Individuals with metabolic conditions like diabetes should seek medical advice.
