  1. Counter Movement Jump Squats By: Nathan Boylan, Bryden Burrell, Hilary Graham

  2. What We’ll Cover • Hypothesis • Analysis Method • Collection Method • Jump Analysis • Errors • Methods • Conclusion

  3. Hypothesis • In the duration of one minute, jump height will continually decrease as more jumps are performed.

  4. Analysis Method • Subject 1 performed task while subject 2 records video • Subject 2 performed task while subject 1 records video • Video files analyzed using Kinovea • Data manually inputted into Microsoft Excel Document • Graphs created to indicate relationship between time and jump height

  5. Collection Method • Equipment • iPad (Camera Application) • Desktop computer • Kinovea • Microsoft Excel

  6. Subject 1

  7. Subject 1 - Data

  8. Subject 2

  9. Subject 2 - Data

  10. Subject 1 – Knee Angle

  11. Subject 2 – Knee Angle

  12. Errors • Subject 1 had 53.2% of his jumps rejected • Subject 2 only completed 56 seconds of the 1 minute requirement. • There is approximately a 5° margin of error on all knee angles

  13. Methods • Have the video recording device on a tripod. • Correct orientation of video file. • Have more visible tracking points on subjects body. • Working with a more advanced software.

  14. Conclusion • Our data and results support our original hypothesis that “In the duration of one minute, jump height will continually decrease as more jumps are performed”
