The validity/reliability/accuracy of sensors used in sport are important to allow for confidence in the quantitative changes in values measured and recorded. The use of first principle physical techniques for evaluating the values recorded by sensors allows for both tracing measures back to known standards and easy replication by others.
This document outlines a seiers of measures designed to assess the accuracy and reliability of the IMU sensors in eo SwimBETTER to detect displacement (distance) ini a controlled condition.
