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

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

Analysis Method 1. Subject 1 performed task while subject 2 records video 2. Subject 2 performed task while subject 1 records video 3. Video files analyzed using Kinovea 4. Data manually inputted into Microsoft Excel Document 5. Graphs created to indicate relationship between time and jump height

Collection Method Equipment i. Pad (Camera Application) Desktop computer Kinovea Microsoft Excel

Subject 1

Subject 1 - Data

Subject 2

Subject 2 - Data

Subject 1 – Knee Angle

Subject 2 – Knee Angle

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

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.

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”
