Nutrition for Swimmers from USA Swimming

Food does NOT make a swimmer swim fast. QUALITY training makes him swim fast - a vital part of quality training is good nutrition! Believe it or not, your swimmer doesn't get fast during practice. In practice she might see her times improving, but her adaptation to training (i.e. getting faster) actually occurs while her body is at rest. Workout is the stimulus that causes this to happen.
