Abstract

There are gender differences in the substrate used to fuel prolonged physical activity. Males rely on carbohydrate and amino acids (97%), while females use predominantly fat (62%) to fuel endurance exercise. This review looks at the mechanisms that regulate these gender differences, with a focus on amino acid metabolism. Gender-selective nutritional recommendations are indicated for physically active individuals and some cardiac patients who engage in intense aerobic activity. © 2005 International Life Sciences Institute.
