SWOLF

The SWOLF value (also SWOLF) is a made-up or suitcase word from swimming and golf and represents a unit of measurement for swimming efficiency . The calculation is based on the number of strokes per lane in relation to the time required. The lower the SWOLF value, the higher the efficiency of the swimmer. The SWOLF value is used to measure individual performance or to document training development and cannot be used for direct comparison between swimmers. The SWOLF value is always a personal value. It is already used in many sports watches and fitness trackers. The measurement method and the recording of the counting of swimming strokes and time measurement required for the calculation by means of devices worn on the body (e.g. watches) is currently the subject of several patent applications.

calculation

The SWOLF is calculated from the sum of the strokes per lane and the time required in seconds.

Example: 25 moves in 40 seconds results in a SWOLF value of 65.
