Quick Data Quality Check in ForceDecks
When possible, it is recommended to run some quick checks after each test to ensure you are capturing high-quality and reliable data.
By checking, you may identify errors within a recording caused by any of the following:
- Individual being distracted
- Poor technique
- Lack of effort
- Plate instability/placement
- Noise generated by nearby impacts (e.g. weights being dropped)
- Cross-talk from plates touching each other or surrounding materials
Errors commonly occur during the following:
- Start of movement
- Take-off
- Landing
The above errors may lead to inaccuracies which are summarised in the table below:
| Metric affected / direction | Time point / phase | Causes |
| Flight time: Contraction time/Eccentric duration ↓ Contraction time ↑ Eccentric duration ↑ Start time to peak force/Power ↑ Average eccentric: Concentric time/Force ratio ↑ |
Start of movement | Excessive movement in pre-jump phase Large impact near platforms prior to jump |
| Jump height (Flight time) ↑ ↓ Flight time: Contraction time/Eccentric duration ↑ ↓ |
Take-off | Large impact near platforms during late concentric phase |
| Jump height (Flight time) ↓ Flight time: Contraction time/Eccentric duration ↓ |
Flight | Large impact during flight triggering landing identifier Contact between plates/surround |
