Problems studied in Biomechanics - continued
PROBLEMS can be QUALITATIVE or QUANTITATIVE
and INFORMAL or FORMAL(using operations/formulae to arrive at the answer from given information)
Qualitative Analysis (involving non-numeric description), performance is described as:
Good, poor, long, heavy, flexed, rotated,
Quantitative Analysis (involving the use of numbers), performance is described as:
Six meters, three seconds, fifty turns, two players, ten dollars
GOLF PROBLEM EXAMPLES:
Qualitative
– Is the swing on plane
– Is the sequencing of body movements (timing) appropriate
– Is the lead wrist in flexion or extension at ball contact
Quantitative
What is the club’s velocity at impact
What is the ground reaction force through each leg
What is the angle between the hip-line and shoulder-line at early downswing
