What This Document Is
This study guide is designed to help students prepare for the fourth exam in KIN 3515, The Physiological Basis Of Activity, at Louisiana State University. It focuses on the cardiorespiratory adaptations that occur in response to training, covering both structural changes and functional responses to exercise. It was created for a Summer 2016 course.
Why This Document Matters
This guide is essential for students needing to review key concepts related to how the cardiovascular and respiratory systems change with physical training. It’s most useful during exam preparation, serving as a concentrated review of material likely to be tested. Understanding these adaptations is fundamental to grasping the physiological principles underlying exercise performance and training program design.
Common Limitations or Challenges
This study guide is a *review* tool, not a comprehensive textbook replacement. It highlights core concepts but doesn’t provide in-depth explanations of all underlying physiological mechanisms. It also doesn’t include practice questions or detailed problem-solving examples. Students will still need to refer to course lectures, readings, and potentially supplemental materials for a complete understanding.
What This Document Provides
The full study guide includes information on:
* Structural and anatomical changes to the heart, blood vessels, and blood volume with training.
* Cardiovascular responses to both submaximal and maximal exercise, including cardiac output, blood flow, heart rate, stroke volume, blood pressure, and efficiency.
* Ventilatory adaptations, including lung volumes and responses to exercise.
* The relationship between oxygen consumption, cardiac output, and the arterio-venous oxygen difference.
* Detailed explanations of cardiac hypertrophy ("athlete's heart") and muscle capillarization.
* The role of the renin-angiotensin system and ADH in regulating blood volume during exercise and dehydration.
* An explanation of hemodilution and sports pseudoanemia, including how to differentiate it from true iron deficiency.
* An introduction to the sympathoadrenal system.
This preview does *not* include detailed explanations, practice questions, or a complete discussion of the adrenal systems. It is intended to provide an overview of the topics covered in the full study guide.
