Adherence
Kinovea video analysis software does not provide interchangeable or accurate measurements of barbell velocity, duration, or range of motion compared to the validated Open Barbell System (OBS) for free-weight resistance training exercises.
Do not use Kinovea to prescribe weights or determine when to stop a set based on velocity. It systematically overestimates speed and range of motion in free-weight lifts because it tracks the total path of the bar (including horizontal movement) rather than just vertical displacement. Use a validated linear position transducer (like the Open Barbell System) or percentage-based training if you cannot afford velocity equipment.
Based upon these findings and the previous validation of the OBS, these devices should not be used interchangeably.
Why this rating
High-quality agreement study using multiple statistical methods (Bland-Altman, Mountain plots, ICC) on a validated comparator.
