V.        Course Description: Components of physical fitness and athletic conditioning, adaptations in the body that result as a consequence of short and long term exercise. Also included are the risk factors encountered by athletes and others involved in physical activity and the development of fitness and conditioning programs.

 

VI.       Relationship of this course to content area knowledge and skills:

 

            Upon competition of this course, the student should have the knowledge and skills to act as a resource person in the area of physical adaptations due to exercise and risk management and reduction. They should also be able to identify and define delineate the principles of health and performance related physical fitness, design programs to assess these components and design programs to increase these components.  These knowledge and skills should also lead the student to participate in practices that promote wellness.
