Movement Analysis
2

• Basic analysis of movement can be done visually
  and should involve the following
• A description of the actual movements which occur
  at the joints involved
• The plane(s) in which the movement occurs
• The muscles producing the movement
• The function of the muscles involved (agonists,
  antagonists, synergists fixators)
• The type of contraction (isotonic -concentric or
  eccentric, isometric)
• The range of the muscle action (inner, middle,
  outer)

Analysis of racket strokes

• There are two phases to striking a ball with a
  racket, the preparatory phase and the striking
  phase

4

• Most actions are rotational in the transverse
  plane and longitudinal axis and the three joints
  concerned are the wrist, elbow and the shoulder
• The elbow is a hinge joint formed by the humerus
  and ulna.
• The shoulder is a ball and socket joint formed
  between the humerus and the scapula
• The wrist forms a condyloid joint between the
  ulna and carpal bones

Preparatory Phase
Joints involved Articulating bones Action Agonist Muscle
Wrist Ulna and carpalRadius and ulna Supination Supinator
Elbow Humerus and ulna Extension Triceps brachii
Shoulder Humerus and scapula Hori. hyper extension Posterior deltoid and latissimus dorsi
6
Striking Phase
Joints involved Articulating bones Action Agonist Muscle
Wrist Ulna and carpal Radius and ulna Pronation Pronator teres
Elbow Humerus and ulna Flexion Biceps brachii
Shoulder Humerus and scapula Horizontal flexion Pectoralis major and Anterior deltoid
Trunk   Rotation External obliques
