Glycogen Sparing Strategy

Meaning

Glycogen Sparing Strategy is a physiological and nutritional approach designed to minimize the utilization of muscle and liver glycogen stores during prolonged periods of physical exertion or caloric restriction. The primary goal is to promote the preferential oxidation of fatty acids as the main energy substrate, thereby preserving the finite glycogen reserves for high-intensity efforts or maintaining euglycemia. This metabolic adaptation is highly sought after in endurance performance and is intricately regulated by key hormones like glucagon and catecholamines. Successful implementation prolongs endurance capacity and stabilizes blood glucose levels.
