Content Details

Domain 1: Basic and Applied Sciences and Nutritional Concepts

  • Human Movement System: Integrates muscular, skeletal, and nervous systems.
    • Kinetic Chain: Impact of joint movement on the entire chain.

Nervous System

  • Central Nervous System (CNS): Brain and spinal cord.
  • Peripheral Nervous System (PNS): Nerves branching off the CNS.
  • Functions: Sensory, motor, and integrative.
  • Subdivisions:
    • Somatic Nervous System: Voluntary control.
    • Autonomic Nervous System: Involuntary control (sympathetic and parasympathetic systems).

Mechanoreceptors

  • Muscle Spindle: Measures stretch and rate of muscle length changes.
  • Golgi Tendon Organ (GTO): Measures tension changes; facilitates autogenic inhibition.
  • Reciprocal Inhibition: Contraction of one muscle relaxes its antagonist.
  • Stretch Shortening Cycle: Eccentric load followed by rapid contraction.

Skeletal System

  • Functions: Provides shape, protection, movement, blood production, mineral storage.
  • Divisions:
    • Axial Skeleton: Skull, rib cage, vertebral column.
    • Appendicular Skeleton: Limbs, shoulder and pelvic girdles.
  • Types of Bones: Long, short, flat, irregular, sesamoid.

Joints

  • Synovial Joints: Movement and shock absorption.
  • Kinetic Chain: Movement at one joint affects others.

Muscular System

  • Purpose: Generates force for movement.
  • Composition: Muscle fibers and fascia.
  • Types:
    • Type 1 (Slow-twitch): Endurance, slower fatigue.
    • Type 2 (Fast-twitch): Power, quick fatigue.
  • Excitation-Contraction Coupling: Electrical signal from CNS triggers muscle contraction.

Conclusion

  • Revisiting Content: Beneficial for both test-takers and experienced trainers.
