Glucose tolerance relates to physical fitness as it indicates how effectively the body processes glucose. Improved glucose tolerance is associated with enhanced insulin sensitivity, which is often a result of regular physical activity and a healthy diet. Those with higher fitness levels typically exhibit better glucose management and lower risk of type 2 diabetes. Regular exercise, especially that which incorporates both cardio and strength training, can significantly improve glucose tolerance. Therefore, maintaining an active lifestyle is essential for optimizing metabolic health and reducing the risk of related chronic diseases.
