Brief Summary

This study aims to evaluate the concurrent validity of a wearable motion sensor (BTS G-sensor) in measuring countermovement jump (CMJ) height. Healthy female volunteers between 18 and 35 years of age will perform CMJ tests. Jump height will be measured simultaneously using the BTS G-sensor and the My Jump smartphone application, which has previously demonstrated validity and reliability. The study will assess the level of agreement between the two measurement methods.

Outcome Measures

Primary Outcomes (2)

• Jump Height Measured with BTS G-sensor Compared to My Jump Application

  Countermovement jump (CMJ) height measured simultaneously with the BTS G-sensor and the My Jump smartphone application. Agreement between the two methods will be analyzed using correlation and Bland-Altman plots.
