![]() ![]() The mean differences between instruments were 1.11 mm for RB, 0.03 m/s for MV, 0.05 m/s for Vmax and 65.91 ms for CPT, all p <. 964) for RB, MV, Vmax and CPT, respectively. The intra-class correlations coefficient between LPT and SHSC-Kinovea showed almost perfect agreement for consistency (.992. ![]() High-speed video recordings with a smartphone at 240 fps were used against a criterion linear force transducer (LPT) for measuring displacement of the barbell (RB), mean velocity (MV), maximum velocity (Vmax) and concentric phase time (CPT). Fifteen athletes were voluntarily recruited for the study (age 22.8 ± 2.9 years, height 182.9 ± 8.9 cm, body mass 79.5 ± 9.6 kg). ![]() The aim of this study was to validate the combination of smartphone high-speed camera and motion analysis software Kinovea methodology (SHSC-Kinovea) to measure kinematic variables of velocity-based training during back squat exercises. ![]()
