In this module you will learn about the various metabolic pathways (carbohydrates, fats and proteins) that are activated in order to supply the necessary energy required for the mechanical work of skeletal muscles during exercise. How these pathways are regulated, the methods for assessing the extent to which specific fuels are being utilized and the overall estimation of your metabolic rate will be addressed. Additionally, the importance of the chemical energy stored in ATP and its requirement for muscular work will be discussed.

In this module you will learn how a number of key physiological systems (muscular, respiratory, cardiovascular, endocrine and immune systems) are regulated during exercise to help maintain homeostasis. These adjustments are critical for exercise to continue for any significant duration. This will include: how the respiratory system adjusts during exercise to ensure proper oxygen delivery and carbon dioxide removal from active muscles; how the cardiovascular system responds to ensure adequate blood flow to various organs, including muscle, during exercise; how the endocrine system plays a major role in regulating key biochemical and physiological responses to exercise and; how exercise influences the immune system and your ability to fight infections.

This module will teach you about the training guidelines needed to optimize your endurance and strength adaptations associated with a regular exercise program. Important nutritional requirements for both endurance and strength training will be addressed. The causes of both muscle soreness and fatigue will be explained. Finally, the effectiveness and mechanisms whereby performance enhancing drugs exert their effect will be covered.
