Description
The biomechanical analysis required videotaping two subjects performing the cartwheel to the best of their ability. Strict protocols were followed to ensure the analysis was accurate. In order to measure distances in the Dartfish program, an object of known length had to be recorded. Subjects were asked to hold a scaling rod for ten seconds before beginning their trials. Subjects recorded four trials each and all data was imported into the Dartfish program. Average trials for both subjects were chosen to be analyzed extensively for strengths, weaknesses and most importantly the overall biomechanics of the cartwheel. The subjects’ video was then broken down into separate frames to show the different phases of the cartwheel. The Dartfish drawing tools were used to illustrate the incorrect positions and form. An explanation was also offered to explain the illustrations and provide feedback on how the corrections were to be made. Basic physics and biomechanical principles were used to explain why the subject was struggling to complete the skill successfully; as well as explain why the corrections were beneficial. A DVD was created of each subject’s analysis so the subjects could watch and apply the corrections to improve their cartwheel.
