Comparison of expert scoring of form on a plank-like exercise versus performance as measured using wearable sensors

In analyzing the accuracy of trainer form scores as a quantitative assessment of athletic form, wearables were used to compare the individuals’ form score to their biomechanics. The Lock and Load drill, one that requires control to lift the opposite leg and hand simultaneously off the ground from push-up position, was used for this comparison. Eighteen athletic males were recruited for this study and completed the task while wearing an Xsens motion capture system. There was little to no correlations found between the scores given by an expert trainer and stabilization of the body measured by the Xsens. There was no trend in synchronisation of limbs.
