Metric validation and reliability
How accurate is Metric VBT?
Metric has been tested against the gold standard in movement velocity tracking 3D motion capture systems, traditional stringed (Linear positional transducer)velocity based training devices, alternative camera-based apps, and accelerometers both internally and externally.
The Metric tracking system matches performance of these commercially available hardware devices and outperforms other smart device applications when used in normal training conditions.
2022 - Internal validation of Metric v0.4 against 3D motion capture found Metric to be reliable and valid.
2023 - Metric v0.5.4 was been externally validated by Taber et al against 3D motion capture and found the Metric app to be a reliable and useful training tool.
2024 - Metric v4.0 was compared with Vitruve Linear positional transducer and found to correlate strongly with that technology for both mean and peak velocity
