Scientific Validity and Reliability Of An IMU-based App To Track Barbell Velocity

Scientific Validity and Reliability Of An IMU-based App To Track Barbell Velocity

INTRODUCTION – Scientific Validity After validating and testing with real users the measurement of running speed with the mobile camera (you can read the presentation here and the validation here), we realized that reliability was not everything when developing technology for athletes. The scientific validity and reliability of Computer Vision to track barbell velocity is …

Spleeft is a valid and reliable app to measure movement velocity at resistance training

INTRODUCTION Quantifying movement velocity is the only way to control intensity and level of effort at the gym. Each velocity is hugely correlated with a percent of the repetition maximum (%RM) (1). Moreover, by monitoring velocity loss during the series you can control the level of effort and fatigue levels during the series (2). Thus, …
