Breaststroke (Beta) is now available for recording breaststroke data, but there’s a few conditions that need to be met to ensure your data comes through cleanly. These will likely feel completely natural to a competitive breaststroker but may be unfamiliar to recreational swimmers.
Lap Detection Requirements:
- Each lap must begin with an underwater pull-out.
- During the pull-out, hands must be at least 35cm / 14 inches below the surface for a minimum of 1.5 seconds.
- Avoid rubbing or squeezing the handsets between your palms too tightly, as this can cause pressure fluctuations and interfere with lap detection.
Turns & Finishes:
- Turns and final touches must be completed with both hands touching simultaneously, as required in racing.
- If a swimmer drops one hand (which is common to do in practice), it could cause detection issues.
Hand Motion & Stroke Data:
- Breaststroke involves continuous underwater sculling, so all hand movements are treated as part of the stroke.
- Any extra motions between laps that aren’t proper breaststrokes can affect hand path alignment and force distribution.
- Upon finishing, avoid sculling - lift the hands out of the water and stop recording immediately to keep your data as clean as possible.
Breaststroke recordings require extra attention to detail. As we continue refining the algorithm, we aim to introduce more validation checks within the technology to help swimmers get the most accurate data possible.
