Abstract | This study aimed to assess the validity and reliability of a commercially available inertial measurement unit (Enode) for measuring barbell kinematics and kinetics during the snatch. In order to assess validity and within and between session reliability, thirteen competitive weightlifters con-ducted two snatches on two separate occasions at 85% of their one-repetition maximum. The Enode sensor was attached to the barbell, with each lift recorded via the devices native application concurrently with an 11-camera motion capture system. Passing-Bablok regression indicated fixed and proportional bias in some horizontal measures of barbell mechanics, but showed no bias in all but one vertical variable. Collectively this suggests that the Enode is a valid tool in the measurement of vertically derived variables from barbell kinematics, but not horizontal. Within and between session reliability showed moderate to excellent ICC’s, with trivial to small differences between repetitions and between sessions. However, between session reliability showed lower levels of variability and thus may help coaches identify changes in technique over time (between sessions) with good accuracy. Overall the Enode offers a practical and affordable option for coaches seeking to monitor weightlifting technique in training environments. |
