Vertical Loading Rate
Calculate vertical loading rate from the supplied measurements.
Description
Average vertical loading rate divides a force change expressed in bodyweights by its time interval.
Average vertical loading rate divides a force change expressed in bodyweights by its time interval. It is a finite-difference rate rather than a trace derivative.1
Calculate vertical loading rate from the supplied measurements.
When to use Vertical Loading Rate
Use this tool to calculate vertical loading rate from the supplied measurements.
Prepare the measured movement, timing, load or preassigned score requested. Keep protocols, units, paired measurements and caller-selected thresholds consistent.
How to use Vertical Loading Rate 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 forceChangeBodyweights, loadingTimeSeconds using the field table and calculation rules, then run the tool.
- Read loadingRateBodyweightsPerSecond. 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 |
|---|---|---|---|
| forceChangeBodyweights | Force change | number | Required |
| loadingTimeSeconds | Loading time | number | Required |
Enter finite values with nonzero time. Signed force changes and times are accepted by the shared ratio calculation; return BW/s.
rate=forceChangeBW/loadingTimeSeconds Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| loadingRateBodyweightsPerSecond | Vertical loading rate (BW/s) | number |

},
"output": {
"loadingRateBodyweightsPerSecond": 30

}Limitations and assumptions
Use a positive physical interval and a documented force convention. No impact trace, peak loading rate or injury assessment is supplied.
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.
