Which principle is not emphasized in Unit 7?

The principle that is not emphasized in Unit 7 is agility. In physical education, the principles of overload, specificity, and progression are fundamental concepts that guide training and fitness programs.

Overload refers to the need to increase the physical demands placed on the body in order to achieve fitness gains. Specificity emphasizes the importance of training the body in a way that directly enhances performance in a particular activity. Progression involves the gradual increase of these demands to ensure continued improvement and to avoid plateaus.

While agility is an important aspect of overall fitness and athletic performance, it is more of a skill-related component rather than a training principle. Unit 7 likely focuses on those foundational principles that inform how to design and implement effective exercise programs, whereas agility is more associated with specific athletic skills rather than the broader principles of physical training.
