What Is Body Composition?

This is an advanced topic for athletes 16 and older. Body composition refers to the different types of tissues that make up your body, including muscle, bone, and fat. It's a more detailed way to understand your body than just looking at the number on a scale, because it helps show how strong and powerful your body is built to be.

2

Performance, Not Appearance

In sports, the goal of understanding body composition is always about performance. For example, having strong muscles can help a swimmer pull through the water faster or a basketball player jump higher. This is not about how you look; it's about how your body is fueled and trained to perform its best in your specific sport.

Why You Need a Professional

Making changes to your body composition must be done safely and with expert guidance. A Registered Dietitian (RD) is a certified expert in nutrition who can create a plan that is right for your body, your sport, and your health. Trying to do this on your own can be ineffective or even harmful, and may not give your body the fuel it needs to compete.
