Running Vertical Oscillation Screen
Compare running vertical oscillation to stride length and a chosen ceiling.
Description
Vertical oscillation relative to stride length expresses bounce as a percentage of horizontal length.
Vertical oscillation relative to stride length expresses bounce as a percentage of horizontal length. A caller ceiling defines the comparison.1
Compare running vertical oscillation to stride length and a chosen ceiling.
When to use Running Vertical Oscillation Screen
Use this tool to compare running vertical oscillation to stride length and a chosen ceiling.
Prepare the measured movement, timing, load or preassigned score requested. Keep protocols, units, paired measurements and caller-selected thresholds consistent.
How to use Running Vertical Oscillation 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 verticalOscillationCm, strideLengthCm, maximumOscillationPercent using the field table and calculation rules, then run the tool.
- Read oscillationToStridePercent, withinTarget. 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 |
|---|---|---|---|
| verticalOscillationCm | Vertical oscillation cm | number | Required |
| strideLengthCm | Stride length cm | number | Required |
| maximumOscillationPercent | Maximum oscillation percent | number | Required |
Enter nonnegative oscillation/maximum percentage and positive stride length using cm. Return ratio percentage and inclusive ≤maximum flag.
percentage=100oscillation/strideLength Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| oscillationToStridePercent | Oscillation to stride percent | number |
| withinTarget | Within target | boolean |

}Limitations and assumptions
No running economy, technique causality or stride-length convention is validated.
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 Cadence Stride Speed Solver: Solve one missing gait speed, step cadence, or step length from the other two. For a complementary task, use Cadence Change Prescription: Translate a planned cadence increase into target steps/min and step-length factor.
