Video Motion Analysis

• The separation movement of a whole into its
  constituent parts for individual study using
  video technology.

3
Video Motion Analysis

• The difference between winning and losing is now
  frequently measured in thousandths of a second or
  fractions of an inch
• Motion analysis is the next frontier in athletic
  training
• Helps analyze the biomechanics of sports

4
Video Motion Analysis

• Reinforce good motion
• Students will have a much better understanding of
  what you are trying to convey, and you can keep
  their motions on file for future comparison
• A picture is worth 1000 Words

5
Video Motion Analysis

• Coaches and athletes have to begin looking
  towards the next true evolutionary step in
  training techniques. That step is technology.
  Technology has dominated every aspect of our
  lives and it will now play an even more important
  role in the making of future athletes.
