Protein fuels growth, maintenance and repair for the body. Fish, chicken, nuts, eggs, beef, milk and cheese provide high quality sources. Swimmers need 0.55 to 0.8g per lb. of body weight, according to the American Dietetic Association. A 150-lb. swimmer needs 82 to 120g of protein a day.

Swimmers need to drink at least a cup of fluid with each meal and snack throughout the day. Swimmers sweat in the water, which causes fluid loss. Chilled fluids lower body temperature and are absorbed faster, according to the Colorado State University Extension. Swimmers need to drink 2 cups of fluid before practice. Swimmers should drink 5 to 10 oz. of fluid every 15 to 20 minutes during practice. Swimmers can consume a sports drink when practicing more than one hour to help replace carbohydrate loss. Swimmers should weigh themselves before and after practice to determine the weight lost from fluids. They need to drink 3 cups for every pound lost.
