To develop a quantitative and qualitative analysis pattern of a record athletic or a sports activity and identify the major movements of upper and lower extremity through open source motion analysis software .

Developing a quantitative and qualitative analysis pattern of a record athletic or sports activity using open-source motion analysis software is a great way to gain insights into the movements of the upper and lower extremities. Here's a step-by-step guide to achieve this:

• Select Open-Source Software: Choose an open-source motion analysis software, we use Kinovea here.

• Data Acquisition: Obtain quality video footage of the athletic or sports activity. Ensure that the video is shot from multiple angles to capture the complete range of motion.

• Calibration: If using an analysis tool, calibrate the software by adding reference markers to the scene. This allows the software to understand the spatial relationships in the video.

• Data Import: Import the video footage into the software. Set the frame rate and resolution appropriately.

• Marker Placement: place markers on key anatomical landmarks on the athlete's body. These markers will help the software track the movement of body parts accurately.

• Analyze the Video: Use the software to track the motion of the athlete's upper and lower extremities. To perform the following analyses:

  • Quantitative Analysis: Measure angles, distances, and speeds of limb movements. The software should provide numerical data about joint angles and trajectories.

  • Qualitative Analysis: Observe the athlete's technique and form. Note any deviations from ideal movements.

• Data Visualization: Create visual representations of the motion data. This could be in the form of graphs, stick figure animations, or 3D reconstructions.

• Identify Major Movements: Review the data to identify major movements of the upper and lower extremities. This might include actions like running, jumping, throwing, or specific sport-related movements like a tennis serve or basketball dribble.

• Iterate: Motion analysis often requires multiple iterations to fine-tune the analysis and improve accuracy.
