Abstract
In order to understand the complexity of punches, measurement under realistic conditions in a training environment is necessary. A crucial element to achieving valid results is a reliable instrument. The aim of the study was to evaluate the metrical characteristics and reliability of kinematic sensors (KS) in specific karate testing as a novel method in the training process. Fourteen male competitors, members of a Serbian national senior and cadet karate team, participated in the study. Segmental acceleration in the different modalities of reverse punch (Gyako tsuki) were measured using KS placed on the hand and body. In relation to the qualitative criterion of the intraclass correlation coefficient (ICC) significance, good reliability (ICC = 0.75–0.90) was observed for eight kinematic variables, while excellent reliability (ICC > 0.90) was confirmed for ten kinematic variables. KS can be considered sophisticated measuring tools providing a reliable base of information for the objectification of assessment as the primary approach to top-level athletes.
