BreastStroke

by NOapps
Breaststroke is a popular swimming style. In Hannover pools (and probably elsewhere) not all swimmers are performing equally well. For later inspection, the BreastStroke app records on the watch how the swimmer swims. It exploits duration, acceleration and angles of the watch on the wrist.

BreastStroke follows a process model of breaststroke swimming. As breaststroke swimming is symmetrical and coordinates arm and leg moves, the watch sensors track the rowing and gliding of the arms, the duration of strokes, glides and rows, the turns of the palms, the pull of the rowing arms and the push of the kicking legs.

With the data observed during a sample, BreastStroke aggregates key features - averages or min/max values - of the swimming style, such as the turn of the hands while rowing or the strength of the leg kick while gliding.

The values of the current sample can be glimpsed on the watch. Up to six samples a time can be downloaded and saved to the user’s iPhone. There the swimming samples are displayed for a closer check. Just in case users are not happy with their performance, they find some links to breaststroke advice, often with video demonstrations.

The BreastStroke app was tested on a watch series 2, 38 mm with an iPhone 7 in pools of 25 m / 50 m size.
