Study Notes
Five Component Functions Model of Exercise Physiology
- This model describes the physiological systems involved in exercise, from rest to movement.
- The model focuses on five key functions: signaling of tissue, force production, energy production, substrate supply, and waste removal.
Physiological Systems of the Human Body
- The following systems contribute to the five component functions:
- Neural System
- Endocrine System
- Lymphatic System
- Muscular System
- Skeletal System
- Digestive (Metabolic) System
- Cardiovascular System
- Respiratory System
- Renal System
- Integumentary System
- Reproductive System
5 Component Functions
- Signaling of Tissue: Neural, endocrine, and lymphatic systems coordinate responses.
- Force Production: Muscle and skeletal systems (including ligaments) generate the force.
- Energy Production: Digestive (metabolic) and endocrine systems play crucial roles.
- Substrate Supply: Primarily driven by circulatory and respiratory systems.
- Waste Removal: Integrated function of circulatory, respiratory, renal, integumentary, and lymphatic systems.
From Rest to Walking
- The neural system initiates muscle contraction and increases heart rate and ventilation.
- ATP (energy) is utilized for muscular force, boosting bioenergetic activity.
- Cardiovascular and respiratory systems deliver nutrients and eliminate waste from the process.
- The process continually adjusts based on activity and feedback.
Physiological Status at Rest
- The information presented investigates how the body's physiological systems function at rest compared to their maximum capacity, across signalling, force production, energy production, substrate supply, and waste removal.
Key Exercise Physiology Concept
- Exercise physiology examines rates and the degree to which body systems are utilized.
Exercise Intensities and Physiological Responses
- Exercise Zones and associated factors, including % FTP, max HR, threshold HR, and RPE are presented. Extensive data charts are included. (refer to page 8).
- EMG activity increases with the intensity of exercise. A data plot shows this relationship. (refer to page 9).
- VO2 (oxygen consumption) and VCO2 (carbon dioxide production) increase with exercise intensity. This is graphically demonstrated. (refer to page 10).
- Heart rate (HR), directly linked to resource delivery and waste removal, displays a correlation with exercise intensity. (refer to page 11)
- Ventilation (VE) directly correlates with CO2 production and waste removal, increasing with exercise intensity. A graph shows this. (refer to page 12).
Deeper Dive into Exercise Physiology
- Signaling: Changes in intensity alter the rate of signal delivery.
- Force Production: Intensity increases internal force requirements; neural and muscular systems adapt.
- Energy Production: Energy utilization increases as more muscle activity demands are placed on the body. Metabolic pathways deliver ATP.
- Substrate Supply: The need to deliver more resources like glycogen, triglycerides, etc., increases with the intensity of exercise. Delivery systems accommodate increased demands.
- Waste Removal: Waste product accumulation escalates with increased intensity. The body responds to effectively remove waste.
Summary
- Each physiological system is intricately interconnected in order to adapt and execute the required tasks during movement. This encompasses all stages from signalling, through force production and energy production, substrate delivery and waste removal. System integration allows for seamless physiological functioning within the context of an organism's external environment.
