Exercise Metabolic Response

Meaning

The Exercise Metabolic Response is the immediate and delayed cascade of biochemical and hormonal changes that occur in the body as a direct result of physical activity. This dynamic response involves a rapid shift in energy substrate utilization, primarily moving from stored carbohydrate to fat oxidation, alongside significant alterations in circulating hormone levels. It is a fundamental adaptive process designed to meet the increased energy demands of contracting muscles and to promote subsequent repair and remodeling. Optimizing this response is key to improving insulin sensitivity, body composition, and overall cardiorespiratory fitness.
