Nutrition plays an essential role in supporting fitness and exercise. If you increase your level of physical activity, your need for nutrients and calories will also increase. In addition, the foods you eat before and after you exercise will have an impact on your performance during the physical activity and on your recovery afterward. Describe the importance of pre- and post-exercise nutrition choices. Provide examples of foods that are appropriate selections for each category. Explain how foods and nutrients (including fluids and electrolytes) help improve a person’s performance during physical activity and their recovery afterward.
