The aim of this study was to determine the most frequent technical errors, and their associated behavioural sequences, in the judo throw osoto-gari, proposing improvements to the way in which judo is taught and learnt. Inexperienced students (n=55, 30 males and 25 females; M=24.8 years, SD=2.3) from the Faculty of Educational and Sports Science at the University of Vigo (Spain) were recorded on digital video while performing the technique. The results of this systematic observational study based in descriptive statistics and the sequential analysis of temporal patterns were obtained via the THEME v.5 software, revealing a series of typical errors when learning the osoto-gari. Specific sequences of errors were identified being able to propose motor tasks and teaching-learning processes to ensure that novices successfully learnt the osoto-gari technique. Recommendations about the use of feedback are also provided.
