Identify the anatomical factors
affecting your sport code.
The anatomical analysis of a movement should include an
examination of the skeletal joint action, a description of segment
motion, an account of the muscle participation, and an
identification of the neuromuscular mechanisms involved.
Anatomical analysis involves analysis of a process rather than a
product. That is, it is a review of how the body accomplishes the
task rather than an in-depth examination of the results. .

Which joint are involved, and what
are their exact movements in the
motor skill?
For each phase of the technique and for each joint participating in the phase, as was done
for the sample analysis of the force phase of the standing long jump.

Which muscles are responsible for
the joint actions, and what is the
nature of their contraction?
The muscular action is identified for each joint movement and recorded
next to the joint actions on the chart (table 1.2). This implies identifying
not only the muscles that are contracting but also their precise function
in the movement and the kind of contraction they are undergoing.
Identification of the force causing the motion facilitates the subsequent
identification of the muscle and type of contraction involved.

Which neuromuscular
mechanisms are likely to help or
hinder the action, and what is the
nature of their involvement?
The muscle-response patterns of well-learned motor skills
involve the integrated action of many reflexes and the inhibition
of others. After repeated viewing of the performance “live” or
film, the student should name and discuss the reflexes that
could be acting at various points in each phase.

Which principles are directly related
to the avoidance of injury?
In any analysis, a set of anatomical principles governing the
safe and effective performance of the movement skill must
be considered. These principles take into account the
structure and function of the human body, human tolerance
of both internal and external stresses, and the efficiency of
movement patterns. Hudson (1995) has also suggested that
it is critical to examine such core concepts as range of
motion, the number of body parts involved, the nature of the
body parts involved, and the coordination of the movement.
In addition, it is important to look at the alignment of the body,
and the reflexes that might be utilized. Anatomical principles
of motion then stipulate the way in which each of these core
concepts apply to a specific movement. In particular,
anatomical principles speak to the qualities associated with
each of these concepts.
