Years ago, using video or film for training and improvement in technique required expensive, bulky equipment. This meant that it was limited to colleges and elite swimmers. For everyone else, coaches and trainers relied on dive masks and underwater windows in the pool. Everything was real-time. Swimmers had to rely on what the coach saw and their suggestions for improvement.
Now we have access to two new tools that make it possible for swimmers to see themselves and others in action:
- Small, relatively inexpensive video cameras such as the “GoPro” with an underwater lens.
- The Internet video sites, such as Vimeo, YouTube, and the Internet Archives.
