To be objective and scienti
fi
c, qualitative analysis needs to use a structured approach,
moving from preparation, through observation, diagnosis
–
evaluation, to intervention
(and review)
–
this approach will be explained fully in Chapter 2. From the outset, the
movement analyst should involve the coach, or whoever commissioned the analysis, in
a
‘
needs analysis
’
, and should keep the coach in the loop at all stages. Qualitative
analysis requires applying basic biomechanical principles to the movement. We need to
know what to observe; coaches have important knowledge and contributions to make
here too.
Qualitative analysts need an excellent grasp of the techniques
–
or movement inter-
actions
–
in a speci
fi
c sport or exercise; coaches have great depth and breadth of that
knowledge. Deterministic models (see Chapter 2) can give a theoretical basis to the
analysis, which can otherwise become discursive. This modelling approach can be
represented graphically so as to be coach-friendly.
Good-quality digital video cameras are needed, with adequate frame rates and
shutter speeds. This equipment is familiar to coaches and extra equipment is rarely
necessary. Qualitative analysis should uncover the major faults in an unsuccessful
performance by an individual or a team; it is the approach actually used by most
coaches and teachers
