Page 12 - Anatomical Terminology, Planes, and Axes of Movement

Anatomical Terminology

Key terms for describing movement and injury locations:

  • Anterior / Posterior
  • Medial / Lateral
  • Proximal / Distal
  • Superior / Inferior

Page 13 - Planes of Movement

  • Sagittal Plane: Involves flexion and extension.
  • Example Activities: Running, squatting.
  • Frontal (Coronal) Plane: Involves abduction and adduction.
  • Example Activities: Jumping jacks.
  • Transverse Plane: Involves rotation.
  • Example Activities: Throwing, twisting.

Page 14 - Axes of Movement

Axes of Movement:

  • Transverse Axis: Movements in the sagittal plane.
  • Anteroposterior Axis: Movements in the frontal plane.
  • Vertical Axis: Movements in the transverse plane.

Page 15 - Functional Anatomy Concept

Overview

Functional anatomy investigates how anatomical structures cooperatively yield movement rather than merely their static forms.

Key Concepts
  • Muscles categorize into prime movers, antagonists, synergists, and fixators.
  • Joint structure dictates the range and type of movement.
  • Muscle actions analyzed in the context of actual sports activities.
  • Example: Consideration of shoulder abduction involving the deltoid (prime mover), rotator cuff (stabilizers), and scapular muscles (synergists).

Page 16 - Principles of Movement and Levers in Sports

Principles of Movement
  • Movement occurs at joints.
  • It is induced by muscle contraction.
  • Movement is under neurological control.
  • Movement efficiency relies on coordination, balance, and posture.
Levers in the Human Body
  • Definition: A lever is a rigid bar moving around a fixed point (fulcrum) when force (effort) is applied to overcome a resistance (load).
  • Components:
    • Bone (lever arm)
    • Joint (fulcrum)
    • Muscle force (effort)
Types of Levers
  1. First-class lever (Fulcrum between effort and load).
    • Example: Neck extension at Atlanto-occipital joint (Nodding).
  2. Second-class lever (Load between fulcrum and effort).
    • Example: Standing on toes (Foot = F, Body weight = L, calf muscle = E).
  3. Third-class lever (Effort between fulcrum and load; most prevalent in sports).
    • Example: Elbow flexion while throwing.
  • Significance: Third-class levers maximize speed and range of motion, vital for agility in sports, biomechanics, and physiotherapy.

Page 17 - Mechanical Advantage of Levers in the Human Body

  • Mechanical Advantage (MA) = extEffortArmextLoadArm\frac{ ext{Effort Arm}}{ ext{Load Arm}}
    • MA = 1: Balance achieved (1st Class levers)
    • MA < 1: Speed & Range of Motion (ROM) benefits (3rd Class levers).

Page 18 - Importance of Levers in Sports Anatomy

  • Enhancement of Movement Efficiency: Efficient movement patterns reduce energy expenditure.
  • Clarification of Muscle Function: Understanding how levers operate elucidates muscle-joint mechanics.
  • Performance Optimization: Guides tailored training programs and technique adaptations.
  • Injury Prevention and Rehabilitation: Leverages anatomical insights to mitigate risk and assist recovery.
