The Body 3 – Health & Physiology
The chapter covers the anatomy and physiology of the muscular, cardiovascular, and respiratory systems as they relate to physical activity, highlighting their acute and chronic adaptations to exercise. It also presents methods to monitor wellness and performance, effective stress management strategies, and approaches to enhance recovery. Moreover, it addresses common performance issues among adolescents and suggests evidence-based corrective actions.

What we have learnt
- The muscular, cardiovascular, and respiratory systems work in coordination to support physical activity.
- Thermoregulation, recovery strategies, and monitoring techniques are vital for optimizing performance.
- Adaptations to exercise include improvements in muscle strength, cardiovascular efficiency, and respiratory function.
Key Concepts
- -- Muscle Fiber Types
- Muscle fibers are categorized into Type I (slow-twitch), Type IIa (fast oxidative-glycolytic), and Type IIb (fast glycolytic), each serving different functional roles in physical activities.
- -- Cardiac Output
- Cardiac output is the volume of blood pumped by the heart per minute, calculated as heart rate multiplied by stroke volume.
- -- Recovery Strategies
- Effective recovery strategies include active recovery, nutritional replenishment, and soft tissue therapy to enhance the body's ability to recuperate from exercise-induced stress.
