Download the validation research that proves Vitruve's high accuracy.
Our Vitruve encoder has established itself as one of the most reliable devices available. It's crucial to emphasize that linear position transducers are the only truly accurate Velocity-Based Training devices. Reliability is defined as follows:
- Never misses a rep.
- Provides consistent data—each repetition yields the same value with minimal error.
Technologies relying on different sensors like accelerometers or cameras may be "validated," but scientific validation doesn't necessarily equate to accuracy in Velocity-Based Training—they typically fall short. The Bland-Altman analysis in the referenced paper demonstrates the unit's consistency.
The reliability document serves as an essential reference, detailing the trustworthiness, consistency, and processes within the system. It outlines measures taken to ensure accurate, repeatable, and dependable data. This document is critical for assuring stakeholders of the system's reliability and integrity, instilling confidence in its outputs and supporting informed decision-making processes.
The document provides a comprehensive summary of Pérez-Castilla et al.'s (2019) study, which assessed the reliability and validity of seven commercially available devices for measuring movement velocity during bench press exercises. The study involved fourteen male participants who completed two testing sessions: one to determine their one-repetition maximum (1RM) in the bench press and another with repetitions against various loads. Movement velocity was measured simultaneously using both an optical motion sensing system (Trio-OptiTrack) and the seven designated devices. The study's findings underscored varying levels of reliability among the devices, with implications for their practical application in assessing movement velocity during weightlifting exercises.
