This paper presents an overview of vitamin and exercise, including the role that vitamin plays in gluconeogenesis and glycogenolysis and changes in vitamin metabolism during exercise. The dietary vitamin intakes of athletes are also reviewed. Most studies report that male athletes have adequate dietary intakes of vitamin , whereas some females, especially those with low energy intakes, appear to have low vitamin intakes. Few studies have assessed the vitamin status of nonsupplementing athletes using the recommended status criteria. The role that vitamin may play in attenuating the rise in plasma growth hormone observed during exercise is also reviewed. Finally, recomrnendations are given for further research in the area of vitamin and exercise.
