Glenn Mills explains to swimmers how to add their own data using an app, emphasizing the importance of athlete engagement in the process. He demonstrates using the annotation toolbar to mark strokes, turns, and speeds, and how to set the start and finish times by identifying strobe lights. Mills highlights the need for athletes to review their races to understand stroke length and rate, as coaches can only track one swimmer live at a time. He also shows how to adjust 15-meter marks for accuracy and how to save the data, which is then automatically sent to coaches. The summary data can be checked for accuracy, ensuring athletes have an active role in their training.

**Action Items**

*   Set the start of the race by tapping the screen when the strobe light is visible in the reflection.
*   Click the stroke button every time the swimmer takes a stroke.
*   Click the turn button when the swimmer completes a turn.
*   Set the finish of the race by holding down on the finish button and scrubbing to the end of the race.
*   Adjust the 15-meter marks by holding down on the mark and moving the swimmer's head to the correct position.
*   Save the data by exiting the video in the upper left corner.
*   Review the data, including the number of strokes taken, and make any necessary corrections.
*   The saved data will automatically be sent to the coach.

**Adding Data Using the App**

*   Glenn Mills explains the process of adding data using the app, starting with the annotation toolbar located in the upper right-hand corner.
*   The toolbar allows for various markups, including voice recordings, which automatically sends feedback to the coach.
*   Glenn introduces the stroke button, which is used to track strokes in different swimming styles: freestyle, backstroke, butterfly, and breaststroke.
*   The turn button is used to mark turns, and the speed button allows adjusting the playback speed to improve data accuracy.

**Setting the Start and Finish**

*   Glenn demonstrates setting the start by focusing on the strobe light and holding down the start button until the strobe is visible in the water's reflection.
*   Once the strobe is identified, the user taps the screen to set the start time.
*   The process for setting the finish is similar, with the user holding down the finish button and scrubbing until the finish of the race is visible.
*   Glenn emphasizes the importance of accurately setting the start and finish times for data collection.

**Tracking Strokes and Turns**

*   Glenn explains that athletes should add their data after the race to engage with the race better and understand their stroke length and rate.
*   The stroke button is used to track strokes, and the turn button is used to mark turns during the race.
*   Glenn mentions that this process can be done live by coaches at the pool, but only for one swimmer at a time.
*   The importance of athletes adding their own data to understand their performance is highlighted.

**Adjusting 15-Meter Marks**

*   Glenn discusses the need to adjust the 15-meter marks due to variations in filming locations.
*   The user holds down on the 15-meter mark and adjusts the athlete's position until the head is right at the mark.
*   This process is repeated for each length of the pool, ensuring accurate data for each 15-meter mark.
*   Glenn emphasizes the importance of zooming in to get as close as possible to the 15-meter mark for accurate data.

**Saving and Reviewing Data**

*   Glenn explains how to save the data by exiting the app in the upper left-hand corner, which reorients the screen.
*   The user can see the data, such as the number of strokes taken, by clicking the clipboard at the bottom of the screen.
*   Glenn demonstrates checking the data by counting strokes and ensuring accuracy.
*   The saved data is automatically sent to the coach, giving athletes an active role in their own training.

**Final Remarks and Encouragement**

*   Glenn concludes the session by encouraging athletes to use the app to add their own data and engage with their races.
*   He emphasizes the importance of understanding stroke length and rate to improve performance.
*   Glenn wishes the athletes a great season and hopes the session was helpful.
*   The session ends with Glenn's positive encouragement for the athletes.
