MOVEMENT ANALYSIS ( analysis of throwing and racket strokes)

2.  Detailed analysis of movement is a complex
activity requiring sophisticated equipment.
However, 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 range of the muscle action
(inner, middle, outer)

3. Analysis of throwing
 Throwing comprises
of two phases, the
preparatory phase
and the throwing
phase.
 Most actions are
rotational in the
transverse plane
and longitudinal axis
and the two joints
primarily involved
are the elbow and
shoulder.

4.  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.

5. Preparatory phase
Joints involved Articulating bones

Posterior deltoids and latissimus dorsi

7.  There are two phases to
striking a ball with a
racket, the preparatory
phase and the striking
phase.
 Most actions are
rotational in the
transverse plane and
longitudinal axis and the
three joints concerned
are the wrist, elbow and
the shoulder
Analysis of racket strokes

8.  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
