I started competitive swimming as a 10 year old in 1960 and I received limited coaching in swimming technique at the Kiwi Swimming Club - see my full account here. I saw no need to swim breaststroke any less vigorously than freestyle, so I ignored how senior swimmers in Otago swam a sedate, and unbeknownst to me at the time, an outdated style of breaststroke. The breaststroke I developed was similar to the modern technique used today apart from a difference in timing. I used to pull to breathe, whereas the modern approach is to pull to stretch to a streamlined position with one's head full submerged enabled by changes in the FINA rules in 1987 which allowed complete submerging during each stroke. Lack of coaching turned out to be to my detriment in butterfly, backstroke, and freestyle, the full extent of which I didn't realise until some 30 years later in 2000 when I first saw video clips of myself swimming. I was horrified at my serious stroke defects in butterfly and especially backstroke and freestyle. I still have major defects in these swimming strokes.
In the year 2000, I developed a dual screen utility using Macromedia Authorware to compare two video clips at different speeds. I now use Camtasia 2022 to display 4 video clips simultaneously on screen and save as an MP4 file. The quality of the video is much superior the simultaneous video clips taken at the Otago University flume in 2013. As an aside, videos of swimming in a flume does not necessarily refect that of how one swims in a pool. I have found that one concentrates on staying in the same position for the sake of the cameras. There are natural accelerations and decelerations, especially in breaststroke and butterfly, when swimming in a pool. If a flume video shows a swimmer in a constant postion on screen, then it is likely that the swimmer is not swimming his or her natural stroke.
The quality of the video clips that Barry Young and I took of each other in 2000 was poor due to limited indoor lighting. In 2008, I took poolside and underwater video clips of David Murphy at the Mosgiel Swimming Pool and he returned the favour by taking video clips of my own swimming technique. Video clips of my swimming at the age of 59 are shown below.
