Snatch Catch Stability Screen
Compare snatch catch depth and sway with caller-defined stability limits.
Description
Snatch-catch stability screening requires acceptable catch-depth percentage and lateral sway.
Snatch-catch stability screening requires acceptable catch-depth percentage and lateral sway. Its composite flag reflects these two supplied criteria.1
Compare snatch catch depth and sway with caller-defined stability limits.
When to use Snatch Catch Stability Screen
Use this tool to compare snatch catch depth and sway with caller-defined stability limits.
Prepare the measured movement, timing, load or preassigned score requested. Keep protocols, units, paired measurements and caller-selected thresholds consistent.
How to use Snatch Catch Stability 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 catchDepthPercent, minimumDepthPercent, maximumDepthPercent, lateralSwayCentimeters, maximumSwayCentimeters using the field table and calculation rules, then run the tool.
- Read depthWithinRange, swayWithinLimit, stableCatch. 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 |
|---|---|---|---|
| catchDepthPercent | Catch depth (%) | number; minimum: 0; maximum: 100 | Required |
| minimumDepthPercent | Minimum depth (%) | number; minimum: 0; maximum: 100 | Required |
| maximumDepthPercent | Maximum depth (%) | number; minimum: 0; maximum: 100 | Required |
| lateralSwayCentimeters | Lateral sway (cm) | number; minimum: 0 | Required |
| maximumSwayCentimeters | Maximum sway (cm) | number; minimum: 0 | Required |
Enter depth/bounds 0–100%, ordered bounds and nonnegative sway/max cm. Return depth and sway flags and their conjunction.
stable=(minDepth≤depth≤maxDepth) AND sway≤maximum Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| depthWithinRange | Depth within range | boolean |
| swayWithinLimit | Sway within limit | boolean |
| stableCatch | Stable catch | boolean |

}Limitations and assumptions
No balance dynamics, bar path, load or injury risk is modeled.
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.
