Purpose of the Course: The classroom and laboratory experiences of this course are intended to provide the student with an opportunity to discuss, observe and become aware of the acute and chronic responses of the human body to physical activity. Mechanisms of neuromuscular, respiratory, cardiovascular, and metabolic control and adaptation during and following activity will be studied. Course Objectives: Upon successful completion of this course, the student should have achieved the following: I. Developed an understanding of the immediate and long-term responses of the systems of the body to physical activity. II. Developed an understanding of the body’s physiological abilities and limitations. III. Developed an understanding of the research processes and limitations, procedures and interpretation of physical performance measurement. IV. Familiarization with the physiological basis of physical training and the practical application of these techniques to teaching and coaching.2Subject Matter to be Presented: I.
