The Swim Analysis Sessions take place in an Endless Pool. This is a swim flume where you swim against a current, so are effectively swimming in one spot. The swimmer being stationary makes it very easy for the coach to observe the swimmers technique and take video footage of the aspects of their stroke the coach wants to work on.
The sessions themselves involve spending a short time getting warmed up and finding a 'flow rate' that feels comfortable for the swimmer. After that some baseline footage is taken, to show the swimmer exactly what they are doing as it stands.
From there, corrections are discussed and are worked through during the session with additional footage being taken throughout. The swimmer gets to take all footage home and after the session notes are emailed through detailing the corrections to keep them on the right path. All the swimmer needs to bring is regular swim kit and a USB memory stick for videos.
