Which of the following is NOT a component of physical fitness?

Nutrition is accurately identified as not being a component of physical fitness. Physical fitness is typically defined by various performance attributes that allow individuals to perform physical activities effectively. The main components often recognized include speed, strength, flexibility, endurance, and cardiovascular fitness. These attributes focus on how the body performs and responds during physical activity and exercise.

Nutrition, while critically important to overall health and exercise performance, does not fit within the classification of physical fitness itself. Instead, it supports fitness by providing the necessary fuel and nutrients the body needs to function efficiently and recover from exercise. Proper nutrition helps improve energy levels, enhances recovery, and influences body composition, but it does not constitute a direct measure or component of physical fitness like the other options mentioned, which are specific attributes of physical capabilities.
