| Summary: | The purpose of this study was to investigate the validity of linear position transducers (LPTs), The Open Barbell System (OBS) and Tendo Weightlifting Analyzer System (TWAS), in comparison to criterion measure Optotrak Certus (OC3D). Further, we aimed to compare LPTs against each other. Twenty-five resistance-trained males were recruited, and reported to the laboratory for one day of data collection. Subjects performed one-repetition maximum (1 RM) testing of the squat, then had a standardized rest before completing one set to failure with 70% 1 RM. There was no significant difference in average velocity (AV) between either LPT vs. OC3D. T-tests revealed significant differences between LPTs and OC3D peak velocity (PV) (OBS: p=0.02080; TWAS: p<0.01). A significant difference was detected between OBS and TWAS PV (p<0.01). OBS and TWAS demonstrated concurrent validity compared to OC3D for AV (OBS: p=0.2014; TWAS: p=0.5466). Neither LPT was a valid measure ofPV (OBS: p=0.0208; TWAS: p<0.01). | |
