Study Notes
Role of Exercise Physiology and Prescription in Physiotherapy
- Exercise Physiology: Focuses on the body's responses to physical activity, including respiratory and cardiovascular systems to aid rehabilitation, assess fitness levels, and manage chronic diseases.
- Exercise Prescription: Involves creating personalized exercise programs for rehabilitation, sports, and chronic disease management, emphasizing progressive overload and functional improvement. Adjustments are based on patient responses to enhance quality of life.
Acute Effects of Exercise Modalities
-
Aerobic Training:
- Heart Rate (HR) increases proportionally with intensity and plateaus during steady-state.
- Blood Pressure (BP) rises due to increased cardiac output; systolic BP (SBP) increases more so than diastolic.
- Respiratory Rate (RR) elevates to meet oxygen demands.
-
Resistance Training:
- HR increases but remains lower than during aerobic activities.
- BP significantly increases for both SBP and diastolic BP (DBP), due to muscle contractions and peripheral resistance.
- RR increases less than during aerobic but rises with higher intensity efforts.
-
High-Intensity Resistance Training:
- HR shows rapid fluctuations with increases during high-intensity intervals and decreases during rest.
- BP elevations include both SBP and DBP.
- RR fluctuations occur, reflecting changes in exercise intensity.
Definitions
- Physical Activity: Any skeletal muscle movement resulting in energy expenditure above resting levels, encompassing exercise, sports, and everyday activity.
- Sedentary Behavior: Any waking behavior involving energy expenditure of 1.5 METs or lower, such as sitting or reclined activities.
- Exercise: Planned and structured physical activity aimed at improving or maintaining physical fitness.
- Physical Fitness: Capacity to perform daily tasks with vigor, without fatigue, and with energy for leisure activities.
Health Burdens of Sedentary Behavior and Inactivity
- Increased risk of cardiovascular diseases, type 2 diabetes, obesity, depression and anxiety, musculoskeletal problems, and osteoporosis.
Mechanisms Underpinning Health Benefits of Physical Activity
- Enhances physical and mental health and overall quality of life.
- Reduces the risk of various health conditions and aids in managing weight.
- Helps maintain and improve blood pressure, cholesterol levels, and blood glucose levels.
- Crucial for rehabilitation relating to injuries, chronic conditions, enhancing functional capacity for daily activities.
Guidelines and Barriers to Physical Activity
-
WHO Guidelines: Provide recommendations for physical activity but need to consider barriers:
- Common obstacles include lack of time, financial constraints, low energy, motivational challenges, insufficient knowledge, and concerns about health risks.
- Addressing barriers can involve reassuring patients about safe exercise levels and developing strategies to incorporate activity into busy schedules.
Exercise Types in Physiotherapy
- Soft Tissue Extensibility: Utilized for muscle tightness or spasticity; promotes flexibility and injury prevention.
- Range of Motion (ROM): Used in rehabilitation post-surgery or for maintaining movement when immobilized.
- Strength Training: Focuses on muscle activation and improving movement patterns; applicable in recovery and enhancing performance in sports.
