ABSTRACT
Micronutrients are involved in many metabolic processes, therefore they play an essential role during exercise. Physical activity increases energy turnover which in turn increases micronutrient requirements. During exercise, there is also an increase in micronutrient losses through different processes. If athletes keep a well-balanced diet providing sufficient energy, it is very unlikely that they will be at risk of micronutrient deficiencies. However, many athletes restrict their caloric intake for different reasons. More than 50% of athletes take some type of micronutrient supplement, being unnecessary in many and even dangerous in others. It has not been shown that micronutrient supplementation has any effect on performance if there are no deficiencies in the athlete. There are minerals that can be deficient in an important number of athletes, especially women, such as calcium and iron, and this may affect the athlete’s health or his or her performance. Supplementation with antioxidants may also show some benefit in selected groups of athletes. Each athlete should be individually assessed for risks of micronutrient deficiencies and a well-balanced diet is recommended with sufficient caloric intake to avoid micronutrient deficiencies.
