Carbohydrate and protein foods are excellent sources of these vitamins. Furthermore, the B vitamins are water soluble and are not stored in the body. Some female athletes may lack riboflavin. Milk products not only increase the riboflavin level but also provide protein and calcium. Minerals play an important role in performance.
Heavy exercise affects the body's supply of sodium, potassium, iron and calcium.
To replenish sodium lost through sweating, eat normally following the competition. Avoid excessive amounts of sodium. Eating potassium-rich foods such as oranges, bananas and potatoes supplies necessary potassium. Salt tablets are not recommended. Sweating naturally increases the concentration of salt in the body.
