Imaging procedures
The researcher verified the photography procedures and the experiment was carried out on Thursday, May 5, 2019 AD at the International Swimming Academy in Menoufia Governorate, taking into account the following:
- Preparing the filming location in terms of lighting, as well as determining the most appropriate place to place the cameras so that the player's image appears in an appropriate and clear size
- Determine the beginning and end of performing the skill with the player so that it is within the camera frame
- Photographing the calibration unit inside the frame for five seconds before the performance begins.
- The teen camera was synchronized using a “sound" effect.
Experiment implementation:
- The player performed 3 attempts, taking into account the rest periods between attempts.
