oHuman movement or any of its aspects described without
measuring or quantifying those characteristics
oInvolves breaking down the movement into its basic elements
then examining those elements from a mechanical perspective
Quantitative
oThe resulting analysis if human movement or any of its aspects
are described with numbers
oInvolves actual measurements of human movement and the
underlying causes of movement
Resolution
Roll
Sagittal Plane
Scaling Factor
oConverting the distances in the pictures to real world distances
oAlso known as conversion ratio
oEqual to the real world distance/measured distance
Systematic
oSystemic Approach Steps:
Describe: what the ideal techniques look like
Observe: how the individual actually moves
Evaluate: the performance based on ideal technique
Provide feedback and instruction to the individual
oMovement is divided into phases on task sheet (preparatory,
movement, and follow-through)
oThe body is divided into different segments on a task sheet –
examines how the athlete puts everything together

Time Stamp
oThe time interval between pictures
Transverse Plane
Yaw
Sample Questions
What are the strengths and weaknesses of qualitative and
quantitative biomechanical analysis?
Explain why reflective markers are places on the body before
recording the performers movements
Describe the orientation of the body in the anatomical reference
position
Why would you choose to analyze movement using a fixed reference
as opposed to a moving reference?
What types of actions occur in the sagittal plane?
What is the scaling factor? What is the purpose of calculating a
scaling factor?
Explain how you would go about determining the time stamp
If a biomechanist wanted to analyze a gymnast doing a cartwheel,
explain where the high speed camera should be places relative to
athlete. What other steps need to be taken in order to be able to
analyze the movement?
