Dolphin Kick Wave Screen
Compare measured dolphin-kick amplitude and frequency with caller-supplied ranges.
Description
Dolphin-kick screening checks wave amplitude and frequency independently against supplied windows.
Dolphin-kick screening checks wave amplitude and frequency independently against supplied windows. Both must pass the composite gate.1
Compare measured dolphin-kick amplitude and frequency with caller-supplied ranges.
When to use Dolphin Kick Wave Screen
Use this tool to compare measured dolphin-kick amplitude and frequency with caller-supplied ranges.
Prepare the measured movement, timing, load or preassigned score requested. Keep protocols, units, paired measurements and caller-selected thresholds consistent.
How to use Dolphin Kick Wave Screen and understand its results
- Prepare the measured movement, timing, load or preassigned score requested. Keep protocols, units, paired measurements and caller-selected thresholds consistent.
- Enter amplitudeCentimeters, frequencyHertz, minimumAmplitudeCentimeters, maximumAmplitudeCentimeters, minimumFrequencyHertz, maximumFrequencyHertz using the field table and calculation rules, then run the tool.
- Read amplitudeWithinRange, frequencyWithinRange, bothWithinRange. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| amplitudeCentimeters | Wave amplitude (cm) | number; minimum: 0 | Required |
| frequencyHertz | Wave frequency (Hz) | number; minimum: 0 | Required |
| minimumAmplitudeCentimeters | Minimum amplitude (cm) | number; minimum: 0 | Required |
| maximumAmplitudeCentimeters | Maximum amplitude (cm) | number; minimum: 0 | Required |
| minimumFrequencyHertz | Minimum frequency (Hz) | number; minimum: 0 | Required |
| maximumFrequencyHertz | Maximum frequency (Hz) | number; minimum: 0 | Required |
Enter nonnegative measured values and ordered nonnegative bounds. Return inclusive amplitude/frequency flags and conjunction.
both=(amplitude in range) AND (frequency in range) Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| amplitudeWithinRange | Amplitude within range | boolean |
| frequencyWithinRange | Frequency within range | boolean |
| bothWithinRange | Both within range | boolean |

}Limitations and assumptions
No wave propagation, propulsion, technique quality or optimal swimming values are inferred.
Numeric inputs must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors. A successfully returned false flag is an evaluated outcome; its meaning is explained above.
Alternative or Complementary methods
Use Swim Golf Score: Compute per-lap SWOLF from seconds plus strokes, for like-for-like lap distances. For a complementary task, use Rowing Drive-to-Recovery Ratio: Calculate rowing drive-to-recovery ratio from the supplied measurements.
