  1. Exercise Assessment & Prescription – Theory and Application:Individualizing Exercise Prescription PHE 419 Fall 2010

  2. Revisiting the context What is ‘physical activity’? • Includes all forms of activity that are performed without the specific purpose of fitness or health - occupational - recreational - sports-related What is ‘exercise’? • An activity for the express purpose of improving fitness or health

  3. Revisiting the context Different types of exercise: • Aerobic (e.g., walking, swimming) • Anaerobic (e.g., sprinting) • Isotonic (e.g., lifting weights) • Resistance training - provides some form of resistance to the contracting muscles to stimulate strength increase • Stretching (should always be part of the exercise plan)

  4. Revisiting the context Terminology: • Aerobic - use of oxygen in the body’s metabolic process - glycogen is broken down to produce glucose, which then reacts with oxygen to produce carbon dioxide and water - reaction releases energy • Anaerobic - initial phase of exercise or short bursts of intense exertion - glycogen is respired without oxygen (far less efficient process

  5. Revisiting the context Different types of exercise: • Aerobic (e.g., walking, swimming) • Anaerobic (e.g., sprinting) • Isotonic (e.g., lifting weights) • Resistance training - provides some form of resistance to the contracting muscles to stimulate strength increase • Stretching (should always be part of the exercise plan)

  6. Revisiting the context Benefits of exercise: • Improves insulin sensitivity • Improves glycemic control in people with type 2 diabetes • Decreases blood pressure • Decreases low-density lipoprotein and triglyceride levels • Increases high-density lipoprotein levels

  7. Exercise Prescription Exercise prescription generally includes the following recommendations: • Type of exercise or activity (e.g., walking, swimming, cycling) • Specific workloads (e.g., watts, walking speed) • Duration and frequency of the activity or exercise session • Intensity guidelines - target heart rate (THR) range - estimated rate of perceived exertion (RPE) • Precautions regarding orthopedic or other concerns

  8. General Guidelines Type of exercise: • Type of exercise or activity (e.g., walking, swimming, cycling) • Specific workloads (e.g., watts, walking speed) • Duration and frequency of the activity or exercise session • Intensity guidelines - target heart rate (THR) range - estimated rate of perceived exertion (RPE) • Precautions regarding orthopedic or other concerns
